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
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, approx. 4 mm. 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.
9. Sockets are available.
