Description
Simple effect linear solenoids of the ERD serie have got a double coil, one of them with low resistive value (pulse coil) and the other one with high resistive value (holding coil).
It is used when a 100% duty cycle and a huge force at the begining of the stroke are needed.
Working
Before the performance, when the solenoid is off (see fig.3), the holding coil must be off by an external microswitch.
The solenoid is fed at its standard voltage Un (between 1 and 2 terminals) and only the pulse coil works (as it has got low resistive value, it will demand much power), and the solenoid shaft moves due to the forces indicated in chart 2.
When total stroke is completed the solenoid shaft must push the microswitch and quit short-circuit of the holding coil, so both serie coils start to work, adding its resistive value and getting little demand of power.

Holding coil
- Power: 4 W
- Duty cycle (ED%): 100%
- Holding force: 60N
Drawing (Solenoid off)
All the solenoids are tested at 20ºC. The force will decrease due to the standard temperature rising, decreasing a 30% at 65ºC. When the temperature is -10ºC, standard current will increase a 15%.
