ST RELAYS
2. High switching capability
High contact pressure, low contact
bounce, and forced separation
structure that radically improves
resistance to contact welding
(1 Form A 1 Form B type equivalent to
TV-3). Strong against lamp inductive
loads, maximum switching capacity
has reached 3,040 VA (8A 380V AC).
3. High breakdown voltage – Optimal
for control in 250 V power circuits
High breakdown voltage has been
achieved. Between contacts and coil of
3,750 Vrms; Surge breakdown voltage
between coil and contact of 6,000 V,
and between open contacts of 1,200
Vrms mean that these relays are
suitable even for 250 V power circuit
control.
6. Automatic cleaning possible
The sealed design means that these
relays can undergo immersion in
automatic washing systems and are
suitable for automatic soldering. Even
in difficult environments, the contacts
remain reliable.
7. Easy to design PC board patterns
Features 4/10 dual-in-line terminals.
Because the lead spacing has a pitch
greater than 7.54 mm .297 inch,
designers can make easy adjustments
with the width of the land size. This,
along with the large insulation
distance, simplifies the drawing of PC
board patterns.
RoHS compliant
8. To improve soldering efficiency,
preapplication of solder to the
terminals is recommended.
4. Improved stability
9. Sockets are available.
Conforms to all types of safety
standards.
FEATURES
1. Even with small form factor,
sensitive enough for direct IC-
driving
Insulating distance of more than 3 mm
secured. Complies with Japan
Electrical Appliance and Material
Safety Law requirements for operating
200 V power supply circuits, and
conforms with UL, CSA and VDE
standards.
The dimensions of this high-density 4-
gap balanced armature are 31 mm ×
14 mm × 11 mm 1.220 inch × .551 inch
× .433 inch. Despite this small size,
high sensitivity is achieved by a
mechanism that incorporates high-
efficiency polarized magnetic circuits
along with our exclusive spring
alignment method. With an minimum
operating power of about 150 mW,
nominal operating power of 240 mW,
this relay can be directly driven by
transistor or chip controllers.
5. Latching types available
In addition to single side stable types,
convenient 2 coil latching types with
memory functions are also available.
Moreover, we offer 2 Form A
specifications which, with double pole
switching for applications such as 250
V power circuit switching, can enable
safer designs.

NOTES
1. PC board patterns for 2 coil latching
types
2. Soldering should be done under the
following conditions:
1)
3. When using, please be aware that
the a contact and b contact sides of 1
Form A and 1 Form B types may go on
simultaneously at operate time and
release time.
When applying relays in power supply
operation circuits for finished products
regulated by the Electrical Appliance and
Material Safety Law, use the pattern
shown below.
250°C 482°F within 10s
300°C 572°F within 5s
350°C 662°F within 3s
2) For automatic cleaning, the boiling
method is recommended. Avoid
ultrasonic cleaning which subjects the
relays to high frequency vibrations, which
may cause the contacts to stick.
It is recommended that a fluorinated
hydrocarbon or other alcoholic solvents
be used.
