Locking solenoid ERB series

bistablemagnetic latching

ERB serie electromagnets are bistable linear solenoids, where the stroke movement from initial (unlocked) to final position (locked) is made by electromagnetic forces, the return to initial position takes place by an inverse polarizing pulse combined with external forces or by an incorporated spring. When it is off, the bistable solenoids has got two working and maintained positions. One will be held by a permanent magnet system and the other one by a return spring or external forces. Its specifications makes this solenoid perfect to use when both unlocking and locking position are kept for a long time.
