NAFSA
NAFSA - ER series
The ER series of electromagnets are a single acting solenoid.
Â
When an electrical connection is made to to coil, the plunger moves through the magnetic field and pushes the shaft along its designated stroke.
Â
Upon removing the electrical connection, the shaft is retracted to its rest position using either a mechanical spring or the load applied.
Â
Many different standard versions are available (please see catalogue PDF below) and application specific designs can be provided for larger volume requirements.
- Single acting, spring or load return
- Up to class F winding (155°C)
- Duty cycle from 0 to 100%
- Up to 234N force
- Customer specific version available
