The combination of an electromagnetic solenoid and permanent magnets is known as latching Solenoids. It closes when electrical pulse is applied on it. Once the pulse has finished the permanent magnets continue to hold the plunger in the closed position. A low current pulse of opposite polarity is supplied to the solenoid coil to release the plunger. The ability to hold in the closed position without the use of power makes the latching solenoid ideal for applications requiring low power consumption or battery operation. We manufacture 12V & 24V Dc Solenoids. We can also provide DC voltages according to the customer requirements.
