IC DRIVABLE PC BOARD  
RELAY FOR INDUCTIVE  
LOAD SWITCHING  
ST RELAYS  
2. High switching capability  
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.  
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.  
RoHS Directive compatibility information  
8.To improve soldering efficiency,  
preapplication of solder to the  
terminals is recommended.  
4. Improved stability  
Conforms to all types of safety  
standards.  
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.  
About Cd-free contacts  
FEATURES  
We have introduced Cadmium free type  
products to reduce Environmental  
Hazardous Substances.  
(The suffix “F” should be added to the  
part number)  
Please replace parts containing  
Cadmium with Cadmium-free products  
and evaluate them with your actual  
application before use because the life of  
a relay depends on the contact material  
and load.  
1. Even with small form factor,  
sensitive enough for direct IC-driving  
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.
