Latching Solenoid

This latching solenoid is energized to move to the latched position with a short voltage pulse. Once the voltage is removed, the permanent magnet maintains the solenoid in the latched position. The solenoid is spring returned to the de-latched position with a short, reverse polarity pulse that cancels the permanent magnet field. Strokes and forces are flexible depending upon solenoid size.
