SP RELAYS
FEATURES
Taking advantage of the 4-gap balanced
armature mechanism, S relays have met
a number of relay needs and earned a
reputation for the characteristics that they
provide. Building on the same structure,
the SP relay was introduced as a highsensitivity power relay to provide nominal
operating power of 300 mW and
minimum operating power of 150 mW
(single side stable and 2 coil latching
types). Even so, with the nominal
switching capacity for the 2 Form C at 15
A, and for the 4 Form C at 10 A, highcapacity switching is possible with small
input. Moreover, taking full advantage of
the excellence of the 4-gap balanced
armature mechanism, we have realized a
small, slim form factor that also has
superior resistance to vibration and
shock. This power relay is often chosen
for NC machines and electrical power
remote monitoring control panels, and for
power supplies used in computers and
other equipment. The SP also often
provides power control for high-end
business and industrial equipment.
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. 2 coil latching types also 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.
