VERTICAL TYPE
LIMIT SWITCHES
(INCLUDES LAMP TYPE)
AZ5
Limit Switches
General use vertical limit switch. Type with a lamp which makes maintenance
convenient; either a neon AC powered lamp or an LED DC powered lamp.
2. Lamps that can be used with a wide
range of voltages
• Lead wiring type <Current leakage: 0>
(LED type only)
• Neon lamp
Because the wiring can be made parallel
to the load, current leakage from the
lamp can be reduced to 0. Even with a
slight leak, the electronic circuit incurring
the leak can be used safely.
Comes in two types: 100V AC and
200V AC , sufficient luminosity is
achieved through the diamond-cut lens.
Also with a long lifespan of more than 20
thousand hours.
4. Corrosion-proof, oil-resistant con-
struction
• LED lamp
Covers 6V to 48V and comes in three
types, 6V AC/DC , 12V AC/DC , and
24 to 48V AC/DC . Uses two highly lumi-
nescent LEDs and in addition, sufficient
luminosity is achieved through the dia-
mond-cut lens.
3. Lamp connection can be either
spring type or lead wire type
• Spring type (wiring unnecessary)
(With neon or LED lamp type)
Wiring is unnecessary because the lamp
is directly connected to the terminals. By
simply changing the direction of the lamp
cover, it is possible to display both lights
during operation (normally closed side)
and no operation (normally open side.)
The protective construction is corrosion-
proof (conforms to IP67.) Also, the lens
and cover are formed simultaneously
with the lamp type, and moreover, a
nameplate is affixed to the upper sur-
face, thereby improving the already-
excellent waterproof capabilities.

LAMP LIGHTING CIRCUIT
1. Spring type
1) When connecting load to N.O. side:
When the switch is at free position, the
lamp is lit, and when the switch operates,
the lamp turns off.
(Use the lamp holder in the same condi-
tion as when it was at the time of ship-
ment.)
2) When connecting load to N.C. side:
When the switch is at free position, the
lamp turns off, and when the switch
operates, the lamp is lit.
(Use the lamp holder, changing it dire-
cion by 180°.)
3) When connecting loads to both N.O.
and N.C. sides:
Same as in 1).
(Use the lamp holder in the same condi-
tion as when it was at the time of ship-
ment. In this case, it is impossible to use
it, changing its direction by 180°.)

CAUTIONS
1. Please use the lamp connection circuit
within the lamp ratings.
2. Nylon is used for a lamp cover. Avoid
using in the atmospheres containing acid
substance.
3. The lamp cover cannot be installed on
previous limit switches.
4. Remove the lamp holder with a v dri-
ver, and insert it in the opposite direction.

CAUTIONS
1) This model uses silver terminals.
Therefore, if used at relatively low fre-
quencies for long periods of time, or if
used with very small loads, the oxidiza-
tion that forms on the contact surfaces
will not wear away and eventually cause
improper contact. For such applications,
use limit switches with gold/metal con-
tacts (e.g. VL limit switches) or ones
meant for small loads (e.g. HL limit
switches).
4) To improve reliability during actual
use, it is recommended that the opera-
tion be checked under installation condi-
tions.
5) If OT is too big, the life of limit switch
will be shortened switching friction. Use it
with enough margin of OT. 70% of OT
standard value will be good for use.
6) Do not use the switch in a silicon
atmosphere. Case should be taken
where organic silicon rubber, adhesive,
sealing material, oil, grease or lead wire
generates silicon.
8) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
9) When used outdoors (in places where
there is exposure to direct sunlight or
rain such as in multistory car parks) or in
environments where ozone is generated,
the influence of these environments may
cause deterioration of the rubber materi-
al. Please consult us if you intend to use
a switch in environments such as these.
10) Do not store in places where organic
gas might be generated or in places of
high dust content or high humidity.
2) This switch is not designed for under-
water use. Do not use the unit under-
water.
3) Do not use the switch where it may
come in direct contact with organic sol-
vents, strong acids, strong alkaline liq-
uids or stream, or in atmospheres con-
taining flammable or corrosive gases.
7) To protect against entry of foreign
matter from the outside, we recommend
sealing as much as possible using con-
duit connectors.

of the limit switches, and is effective in detecting
when direction and conditions are uneven. In order
to absorb the movements after operation in the actu-
ator part, work slippage tolerances are also large.

CAUTIONS FOR USE
ꢀ DESIGN OF OPERATING DOG AND OPERATING SPEED
Pay attention to the following points
when designing the dog for limit switch
operation.
1. Make the dog faceplate as smooth
as possible.
5) Roller plunger type
3) 0.5m/s ! V&2m/s
α

2. Adjust both the dog angle and the
set arm angle as below, depending on
the operating speed.
3. The depth (h) of the dog effects the
lifespan of the limit switch. Therefore,
set the depth to a maximum of 80% of
the Total Travel (T.T.)
4. The relationship between the speed
of the dog (V = m/s) and the tip angle
(α) is as follows:
θ

Even if overriding the dog, set the for-
wards and rearwards motion exactly
the same, and avoid any settings that
make the actuator accelerate rapidly
from the dog.
The maximum tolerable speed can be
extended by further reducing the dog
rise angle from 45° when 0.5m/s !
V&2m/s. It is necessary to set the arm
so that the dog’s cutting surfaces are
always parallel (θ o = 90°– α)
1) V&0.2m/s
5. Operation speed
α = 45° to 90°
1) When the operation (acting and
reverting) speed is exceedingly slow,
switching of the contacts will become
unstable and this could cause prob-
lems such as failure to make contact
and welding. As a guide, the speed
should be at least 1mm/s.
2) When the operation (acting and
reverting) speed is exceedingly fast,
be careful because the violent motion
could cause breakage and with
increased frequency, contact switching
will not be able to keep up. As a guide,
the switching frequency should be
within 20 times per minute.

As a rule, α = 45° is optimum.
If overriding the dog, set the arm per-

is increased.
2) V&0.5m/s

Because the arm jiggle is as a mini-

so that it travels perpendicularly and
the arm angle to 45° is optimum.

CAUTIONS FOR USE
ꢀ PROTECTION CIRCUIT
1. The ON/OFF circuit for the guidance
load may suffer contact damage due to
surges or inrushes when the power is
turned either ON or OFF.
Consequently, insertion of a protective
circuit as per the following diagram is
recommended, in order to protect the
contacts.
2. Do not connect either irregular poles
or power sources to a switch contact.
Power connection examples (irregular
pole connection)
3. Avoid circuits where power may find
a way between the contact points (as
this may cause welding.)

CAUTIONS FOR USE
ꢀ CAUTIONS FOR USE
1) Do not attempt to physically alter
any part of the switch itself, such as
the actuator, or switch attachment
vent, as this may cause alterations to
both characteristics and performance,
and damage the insulation.
2) Do not pour any lubricants such as
oil or grease onto the moving parts of
the actuator, as there is a possibility
that this will cause a malfunction due
to seepage into the inside, and impair
the motion. Silicon-based grease in
particular affects the contact points
badly.
3) If the switches are not to be used for
an extended period of time, their con-
tact reliability may be reduced due to
oxidation of the contact points.
Because accidents may result from the
impaired conductivity, always imple-
ment a check beforehand.
4) Prolonged continuous use of the
switch hastens deterioration of the
parts (especially the seal rubber) and
may cause a malfunction in the
release. For this reason, always imple-
ment a check beforehand.
5) Usage in the vicinity of either the
switch operating position (O.P.) or the
release position (R.P.) results in unsta-
ble contacts. If using the NC contact
point, set the actuator to return to the
free position (F.P.) Also, is using the
NO contact point, hold the ratings val-
ues down to 70 to 100% for the over-
travel (O.T.)
7) Do not apply unreasonable force to
the actuator, as this may result in dam-
age and impaired movement.
12) Long term storage (including dur-
ing transport) in high temperature or
high humidity environments or where
the atmosphere contains organic or
sulfide gas, will cause sulfide or oxide
membrane to form on the contact sur-
faces. This in turn will cause unstable
or failed contacting that may lead to
functional malfunction. Please verify
the atmosphere when storing and
transporting.
13) Packaging should be designed to
reduce as much as possible the poten-
tial influence of humidity, organic gas,
and sulfide gas, etc.
14) Please avoid sudden changes in
temperature. This is a cause of switch
deformation and encourages the seal
structure to breathe, which may lead to
seal failure and operational malfunc-
tion.
8) The switch, if dropped, may break
due to excessive vibration and impact.
Therefore, please use extra caution
when transporting and installing.
9) Condensation inside the switch may
occur if there are rapid ambient tem-
perature changes when the switch is in
a high temperature and humidity.
Since this occurs easily during marine
transport, be extra cautious of what the
environment will be when shipping.
Condensation is the phenomenon in
which water vapor condenses into
switch-adhering water droplets when
the temperature rapidly drops in a
high-temperature, high-humidity
atmosphere or when the switch is
quickly moved from a low temperature
location to a place of high temperature
and high humidity. It is the cause of
insulation deterioration and of rust.
10) Be careful of freezing in tempera-
tures below 0°C. Freezing is the phe-
nomenon in which moisture adhering
to the switch from condensation or
when in unusually high-humidity envi-
ronments freezes onto the switch
when the temperature drops below the
freezing point. Please extra caution
because freezing can lock moving
parts, cause operational delays, or
interfere with conductivity when there
is ice between the contacts.
15) If installing a thermoplastic resin
case, the use of a spring washer tight-
ened directly against the case will
cause the case to collapse and
become damaged. Therefore, please
add a flat washer before tightening.
Also, be careful not to install if the
case is being twisted.
16) For the purpose of improving quali-
ty, materials and internal structure may
be changed without notice.
17) When used outdoors (in places
where there is exposure to direct sun-
light or rain such as in multistory car
parks) or in ambient temperature envi-
ronments where ozone is generated,
the influence of these environments
may cause deterioration of the rubber
material. Please consult us if you
intend to use a switch in such environ-
ments.
6) If the actuator is forced beyond its
total travel (T.T.), the internal mecha-
nism may be damaged. Always use
within the T.T.
11) In low-temperature, low-humidity
conditions, plastic becomes brittle and
the rubber and grease harden, which
may lead to malfunction.
ꢀ PRECAUTIONS RELATING TO THE INSTALLATION ENVIRONMENT
Avoid using in silicon environments
such as organic silicon-based rubber,
solvents, sealants, oil, grease, or
wiring.

FOREIGN STANDARDS OVERVIEW
1. International Standards

3. Europe
EN standard
International Electrotechnical Commission
By promoting international cooperation toward all
problems and related issues regarding
standardization in the electrical and electronic
technology fields, the IEC, a non-governmental
organization, was started in October, 1908, for the
purpose of realizing mutual understanding on an
international level. To this end, the IEC standard
was enacted for the purpose of promoting
international standardization.
European Standards/Norme Europeennee
(France)/Europaishe Norm (Germany)
Abbreviation for European Standards. A unified
standard enacted by CEN/CENELEC (European
Standards Committee/European Electrical
Standards Committee). EU and EFTA member
nations employ the content of the EN standards into
their own national standards and are obligated to
abolish those national standards that do not agree
with the EN standards.

(1) Germany
UL (Underwiters Laboratories Inc.)
VDE (Verband Deutscher Elektrotechniker)
The VDE laboratory was established mainly by the
German Electric Technology Alliance, which was
formed in 1893. It carries out safety experiments
and passes approval for electrical devices and
parts. Although VDE certification is not enforced
under German law, punishment is severe should
electrical shock or fire occur; therefore, it is, in fact,
like an enforcement.
This is a non-profit testing organization formed in
1894 by a coalition of U.S. fire insurance firms,
which tests and approves industrial products
(finished products). When electrical products are
marketed in the U.S., UL approval is mandated in
many states, by state law and city ordinances. In
order to obtain UL approval, the principal parts
contained in industrial products must also be UL-
approved parts.
LISTING MARK
VDE
Fig. 1
RECOGNITION MARK
UL approval is divided into two general types. One
is called “listing” (Fig. 1), and applies to industrial
products (finished products). Under this type of
approval, products must be approved
unconditionally. The other type is called
“recognition” (Fig. 2), and is a conditional approval
which applies to parts and materials.
TÜV (Technischer Überwachungs-Verein)
TÜV is a civilian, non-profit, independent
organization that has its roots in the German Boiler
Surveillance Association, which was started in 1875
for the purpose of preventing boiler accidents. A
major characteristic of TÜV is that it exists as a
combination of 14 independent organizations (TÜV
Rheinland, TÜV Bayern, etc.) throughout Germany.
TÜV carries out inspection on a wide variety of
industrial devices and equipment, and has been
entrusted to handle electrical products, as well, by
the government.TÜV inspection and certification is
based mainly on the VDE standard.
Fig. 2
CSA (Canadian Standards Association)
Certification
This was established in 1919 as a non-profit, non-
governmental organization aimed at promoting
standards. It sets standards for industrial products,
parts, and materials, and has the authority to judge
electrical products to determine whether they
conform to those standards.The CSA is the ultimate
authority in the eyes of both the government and the
people in terms of credibility and respect. Almost all
states and provinces in Canada require CSA
approval by law, in order to sell electrical products.
As a result, electrical products exported from Japan
to Canada are not approved under Canadian laws
unless they have received CSA approval and
display the CSA mark. Approval is called
TÜV certification can be obtained from any of the 14
TÜVs throughout Germany and has the same
effectiveness as obtaining VDE certification.

“certification”, and products and parts which have
been approved are called “certified equipment”, and
display the mark shown in Fig. 3. The mark shown
in Fig. 4 is called the “Component Acceptance”
mark, and indicates conditional approval which is
applicable to parts. The C-UL mark shown in Fig. 5
(finished products) and Fig. 6 (parts) indicates that
the product has been tested and approved in UL
laboratories, based on UL and CSA standards,
through mutual approval activities.

CE MARKINGS OVERVIEW
The EN standards were established as
universal EU standards in order to facili-
tate EU directives. These standards
were merged with the international IEC
standards and henceforth reflect the
standards in all countries. Also, the CE
markings show that products conform to
EC directives, and guarantee the free
flow of products within the EC.
Limit switches conforming to EN/IEC standards
The limit switches shown below conform to both EN and IEC standards, and may dis-
play the CE markings.

What are EN standards? CE markings and EC
An abbreviation of Norme Europeenne
(in French), and called European
directives
The main EC directives that are to do
with machinery and electrical equipment
are the machinery directive, the EMC
directive, the low voltage directive, and
the telecom directive. Although these
directives have already been issued, the
date of their enactment is different for
each one. The machinery directive was 1
January 1995. The EMC directive was 1
January 1996, and the low voltage direc-
tive was enacted from 1 January 1997.
The telecom directive was established by
the separate CTR (Common Technology
