Description

SJ-S-112DM is PCB 12V, Relay. A relay allows a low-power electrical signal, such as from a microcontroller or sensor, to control a much larger current or voltage, such as required to drive a motor or light bulb. This allows a small electronic device to control a much larger one, or to isolate the low-power circuit from the high-power one. Relays are used in a wide range of applications, including automotive systems, HVAC systems, and computer power supplies.

Features

1. 1Pole, 12V, 0.45W, 1form a ( SPST NO )

2. Small size at a 3, 5 or 10amp switching capacity

3. Surge resistance of 5000v

4. Washable available
