SP Relay

Caution
Product Description
2c 15 A, 4c 10 A polarized power relay.
[Features]
· High sensitivity: Rated power consumption is 300 mW.
· Plug-in terminal / Printed circuit board terminal.
· Latching types also available.
· Mounting boards are available which can be directly mounted to a chassis as well as a DIN rail.
· Terminal blocks are also available.
[Applications]
· Ideal for power equipment / industrial equipment.
- UL, CSA, TUV approved. Protective structure: dust cover type.
- Small, slim structure. Size of relay is Width (25.6 mm) × Length (50 mm) × Height (22 mm), facilitating reduction of device size.
- The high-efficiency polarized electromagnetic mechanism in conjunction with an exclusive spring alignment method achieves levels of sensitivity higher than relays that have been available up to now. Minimum operating power is 150 mW for both 2c and 4c, single and 2 coil latching types, so direct drive by transistor/IC is possible.
- Constructed with twin contact and minimal contact bounce, offering high reliability. Long operating life.

- *1: Micro load level at estimated value for lowest limit at which opening/closing is possible. This value can change depending on the opening/closing frequency, environmental conditions and expected reliability standards, so when using, we recommend checking with the actual load.
- *2.: Ambient operating temperature upper limit level is the highest temperature that accommodates the maximum temperature for increase in coil temperature value.
