Rated Current 40A Universal Automotive Relay Sealed BM940-C-12VDC Large Capacity

Universal Automotive Relay Description:

BM940 series universal automotive relay has a large contact load, and a rated current is 40A, but the maximum is 45A at 14VDC, which can suffer a big inrush current. Small size, PCB mounting,11mm pin pitch for EU type,8mm pin pitch for USA type, SPST and SPDT to option, especially use in automatic control equipment and automobile industry.

Universal Automotive Relay introduces:

The relay is kept in the released state by the permanent magnet. After the working voltage is applied, the electromagnetic induction makes the armature and the permanent magnet generate an attractive and repulsive torque, resulting in a downward movement, and finally reaches the state of attraction. When the relay is working, the electromagnet is energized, the armature is sucked down to contact, and the working circuit is closed. When the electromagnet is powered off, it loses its magnetism, and the spring pulls up the armature to cut off the working circuit. Therefore, the relay is a switch that uses an electromagnet to control the on-off of the working circuit.
