VOLTAGE MINIATURE RELAY DS RELAYS

FEATURES

1. Breakthrough height of 9.8 mm .386

inch beats the 10 mm .394 inch limit

1c, 2c, and 4c all have the same height

(9.8 mm .386 inch). The width of the relay

is also the same (9.9 mm .390 inch).

Since the only size variable is the length,

the shared form makes mounting on

printed printing wiring boards easy.

2. Suitable for use in difﬁcult

environments

Epoxy resin seals the parts and cut off

the external atmosphere, thus enabling

use in difﬁcult environments.

3. Can be used with automatic solder

and automatic wash systems

Automatic soldering and automatic

washing can be carried out once the

parts are mounted on PC boards.

4. Gold-clad twin contacts ensure high

reliability

Highly stable gold cladding on the

contacts ensures that contact resistance

changes little over time. Furthermore, the

use of twin contacts, a conﬁguration that

performs with superior contact reliability,

ensures extremely low contact failure

rates even under low level loads.

5. Polarized magnetic circuits realize

resistance to shock and vibration

High-performance polarized magnetic

circuits that utilize the energy of

permanent magnets have made it

possible to create relays with strong

resistance to shock and vibration.

6. DIL terminal array enables use of IC

sockets

7. Widening scope of application with

multicontact latching

In addition to single side stable types, you

can take advantage of the memory of

functions of convenient 1 coil or 2 coil

latching relays.

TYPICAL APPLICATIONS

Besides telecommunications, measuring

devices, ofﬁce equipment, computers

and related equipment, DS relays are

also recommended for a broad range of

applications including business devices,

audio systems, and industrial equipment.

1. Coil connection

When connecting coils, refer to the wiring

diagram to prevent mis-operation or

malfunction.

2. External magnetic ﬁeld

Since DS relays are highly sensitive

polarized relays, their characteristics will

be affected by a strong external magnetic

ﬁeld. Avoid using the relay under that

condition.
