FEATURES
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.

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.
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.
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.
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.
8. To improve soldering efficiency, 
preapplication of solder to the 
terminals is recommended.
About Cd-free contacts
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.
