Elettrostart Solenoids double coil 12V

Dual coil solenoids have two windings. One as an intermittent-service pulling winding involved in the initial phase for approximately 150 ms, with the function of moving the plunger. The second as a continuous-service holding winding, with the function of maintaining the plunger in position.

For a proper operation of the solenoid, it’s indispensable for the plunger to reach the end of and to obtain the perfect adherence to the bottom.
