Elettromagneti Latching Solenoids > Type RM1
Typical use as holding solenoid.
Type RM1 solenoid is a magnetically latching solenoid designed for DC coil supply. To close its plunger, the coil is pulse energised at nominal voltage (Vn) for at least 50 milliseconds. The solenoid will maintain its plunger closed as long as required, even interrupting the supply voltage, due to the action of a permanent magnet. Hold force is 1200 grams. To release the plunger, the coil must be fed by an inverted polarity current pulse at a given release voltage.
Typical use as (low consuming) linear pull solenoid.
This solenoid develops a pull action force of 200 grams at 3 mm, when suitably energised by a 2.5 Vn pulse not exceeding 100 milliseconds. The solenoid will maintain the plunger closed as long as required, even interrupting the supply voltage, due to the action of a permanent magnet (virtually reducing down to zero both current consumed and heat). To release plunger, coil must be fed by an inverted polarity current pulse at the release voltage.
