2c 15A, 4c 10A polarized
power relays SP RELAYS
Protective construction: Dust cover type
RoHS compliant
FEATURES
1. Small, slim form factor
Facilitating the form factor reduction of
devices, the overall height of the relay
package is less than half that of our HP
relay.
2. High sensitivity
The high-efficiency polarized
electromagnetic mechanism in
conjunction with our exclusive spring
alignment method achieves levels of
sensitivity higher than relays that have
been available up to now. For both the
2 Form C and 4 Form C single side
stable and 2 coil latching types, the
150 mW minimum operating power
level allows direct driving by transistor
or chip controllers.
3. High reliability and long life
With a structure that ensures almost
perfectly complete twin contact and
minimal contact bounce, you get
greater reliability than has so far been
provided by power relays.
4. Latching types also available
1 coil latching and 2 coil latching types
are available. In cases where it was
formerly unavoidable to use plural
relays for large power memory, you
can now use a single SP relay.
5. Strong resistance to vibration and
shock
Our balanced armature technology
well withstands vibration and shocks. It
provides strong resistance to vibration
and shock.
6. Terminals and mounting boards are
available
TYPICAL APPLICATIONS
1. Electrical power device
2. Robots
3. Railway signal equipment

Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
