GEEPLUS Inc. TO Series Open Frame Solenoid Model TO-0420

Latching solenoids are solenoids with permanent magnet; they are mainly manufactured as Open Frame Solenoids. Latching Solenoids exhibit magnetic attraction between plunger (moveable iron component) and pole piece (fixed iron component) with no electrical power applied. Latching solenoids are ideally suited to applications where the "moving" time is very short compared to holding time in the closed position, and where the system may be required to maintain either the open position or the closed (pulled in) position for a prolonged period of time. General characteristics of Latching Solenoids: stroke up to 15mm (depending on type) holding force up to 36N (in endposition, deenergised (no current)) bistable versions (dual coil) available special version for higher actuation force (lower holding force): Leakage Pole Type life time up to >5 million cycles miniature versions: standard dimension from 4 x 8 x 15mm, custom design even smaller! many mechanical options
