High Reliability Relay for
Various Applications
DS RELAYS
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 2 coil
latching relays.
FEATURES
1. Breakthrough height of 9.8 mm
.386
inch
beats the 10 mm
.394 inch
limit
1c and 2c 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.
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.
