NAFSA

NAFSA - ER series

The ER series of electromagnets are a single acting solenoid.

 

When an electrical connection is made to to coil, the plunger moves through the magnetic field and pushes the shaft along its designated stroke.

 

Upon removing the electrical connection, the shaft is retracted to its rest position using either a mechanical spring or the load applied.

 

Many different standard versions are available (please see catalogue PDF below) and application specific designs can be provided for larger volume requirements.
