ZLS Series Global Limit Switches
STANDARDS
IEC 947-1 explains the general rules relating to Low-voltage
GENERAL INFORMATION
ZLS series limit switches are specifically designed for world-
wide applications and is supported by Honeywell global
resources for sales and after sales service.
ZLS series limit switches are designed to the latest IEC
standard are available and include a wide range of EN50041
and EN50047 type switches. Miniature EN50047 limit
switches are available in metal and double insulated
enclosures and a metal enclosed 3-cable entry version
(EN50047 mounting compatible) is also offered.
Standard ZLS switch circuit variations include 2 and 3-circuit
versions with forced disconnect mechanism. ZLS includes
features to make quick installation easier and safer.
Customers will benefit from Honeywell’s vast experience in
serving world industries over many years.
switchgear and controlgear. The purpose of this standard is to
harmonize as much as possible the product performance and
test requirements for equipment where the rated voltage does
not exceed 1,000 VAC or 1,500 VDC.
IEC 947-5-1 is part 5 of the general rules which relates to
Controlcircuit devices and switching elements. Also within this
part there is a section which considers Special Requirements
For Control Switches With Positive Opening Operation. Any
control switch which has this positive opening operation and
conforms to these special requirements will be marked on the
outside of the product with this symbol:
The Contact Element Form defines the configuration of the
contacts and the number of contacts within the switch. e.g.
Form Za – both contact elements have the same polarity.
Form Zb – the two contact elements are electrically separated.
Most ZLS versions are interchangeable with almost all other
makes of EN50041/47 switches.
The Utilization Category defines the type of current carried (AC)
Alternating current, (DC) Direct current and the typical application
in which the switch is used e.g.
AC15 – Control of Electromagnetic Loads (less than 72VA)
DC13 – Control of electromagnets.
TYPICAL APPLICATIONS
□ Machine tools: metal fabrication equipment, presses,
transfer lines and special machinery
□ Material handling equipment: conveyors, elevators, cranes
and hoists
The contact rating Designation relates to the utilization
categories and defines the conventional thermal current lth (A),
rated operational current le (A) at rated operational voltages Ue
□ Packaging machinery and process equipment
□ Textile machinery
and the VA rating e.g.
A600 – The ‘‘A’’ denotes the maximum VA rating (AC) and the ‘‘600’’
□ Construction machinery and equipment, vehicles and lift
trucks
denotes the maximum rated (AC) voltage.
Q300 – The ‘‘Q’’ denotes the maximum VA rating (DC) and the ‘‘300’’
denotes the maximum rated (DC) voltage.
FEATURES
□ Designed to the new IEC standard for world-wide
applications
□ Positive opening of normal closed contact meets IEC947-
5-1-3 safety standard.
These IEC standards have been adopted by CENELEC (The
European Commitee for Electrotechnical Standardization) and
have been identified by replacing IEC with EN 60 e.g.
IEC 947-5-1 then becomes EN 60947-5-1.
□ UL, CSA, and CE
□ Sealing up to IP/65/ IP 67
□ International conduit sizes
□ Design for ease of installation
□ Eleven basic switch versions, Wide choice of actuators
CENELEC has defined the dimensions and characteristics of two
types of limit switch in the standards EN 50041 and EN 50047.
These standards relate to Low voltage switchgear and
controlgear for industrial use and define the enclosure
dimensions, the operating point for various head actuators, the
earth terminal requirement, the terminal marking and the
minimum degree of IP protection.

How to read and understand the bar chart
Look at Figures A and B as examples. Actuator type
The following example relates to a unit which has a snap action
basic and which has a roller pin plunger actuator i.e. ZLCB01C.
When reading these bar charts follow these rules:
1. Check what type of actuator was used to test the product, this is
on the drawings which show the head style available. It will be one
of two types:
used for test is the linear Cam travel type (b) shown
left. The start point is at the arrow marked ‘‘A’’ (See fig.
B). This shows the free position to be 5.3mm from the
vertical center line of the unit. At this stage there is a
circuit between the terminals 21-22 but no circuit
between terminals
a) Vertical travel plunger
13-14. The unit can be actuated until it reaches the
operating position which is 10.5 mm from the center
line – a travel distance of 10.5 – 5.3 =5.2 mm from the
free position. At this point the circuit arrangement
changes – no circuit between 21-22 but making a
circuit between 13-14. If, however, the contacts of
terminals 21-22 weld together and will not separate, a
mechanical safety feature will take effect if the switch is
travelled past the point from which positive opening is
assured, 13.9 mm. Actuator can continue to travel to
the end position (O.T. Overtravel Position) at total
travel position 17.3mm. As the switch returns it
reaches the release position at 8.9 mm from the center
line. The circuit will change back to the original state
and the difference between the operating position and
the release position gives what is known as the
differential travel i.e. 10.5 – 8.9 = 1.6 mm. The asterisk
(*) indicates the point from which the positive opening
is assured.
b) Linear cam travel
2. Start reading from top left of figure B, at the arrow labeled ‘‘A’’.
3. Follow the black arrows and the black strip on the chart. The
black strip indicates that there is a circuit between the terminals
whose numbers are shown on the left and when white there is no
circuit.
All dimensions are in mm/(inches).
