Electromagnet under tension.

* On request, it can be supplied in any other dimension.


  1. Voltage under demand: They can be manufactured at any voltage between the maximum and minimum voltage values shown in the chart.
  2. To feed in alterning current the solenoid will have a rectifier incorporated in the coil.
  3. The duty cycles described in the chart are standard, they can be manufactured in any intermediate cycle.
  4. If any variation from the original is needed, please ask us.
  5. The terminals can be changed by leads.
  6. Earthing is recommended if the metallic parts are accessible..

Ordering code: ER21/C --V ED---% - Mounting position - Spring


  • Standard voltage:24Vdc Duty cycle: ED100%: Mounting position A: With spring : ER21/C 24Vdc ED100% A RS
  • Standard voltage:12Vdc Duty cycle: ED15%: Mounting position C: Without spring : ER21/C 12Vdc ED15% C RN

ATTENTION: When using for lifting and handling loads must choose a minimum safety factor of 3, the weight of the load must be at least one third of the holding force.
