Latching Solenoids

Our latching solenoids utilize a permanent magnet in conjunction with the solenoid coil to maintain the position of the plunger with no current applied. The latching solenoid can perform push, pull, hold and release operations with only an instantaneous pulse of current, thus offering a significant power-saving efficiency and maximum life. Latching solenoids are also found in bi-directional magnetic latching open frame versions. These models electromechanically power the load in both directions, and hold it magnetically latched in either position indefinitely, without power. These features make a latching solenoid ideally suited to continuous duty applications, since even without power, the armature and load will remain latched in the energized position. Applications for latching solenoids include automatic door closers, locks, latching mechanisms, medical equipment, security devices, and battery powered equipment.
