DC Latching Solenoids

DC Latching Solenoids are a combination of an electromagnetic solenoid and permanent magnets. DC Latching Solenoids electrical pulse is applied to the solenoid coil causing it to close. Once the pulse has finished the permanent magnets continue to hold the plunger in the closed position. To release the plunger, a low current pulse of opposite polarity is supplied to the DC Latching Solenoids coil. A return force is required for this operation, and the fitting of a return spring can assist with this opening. 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.
