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 1,200Vrms 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

.118 inch 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

9. Sockets for PC board and soldering are available
