In almost all
sizes two different armature shapes are available: flat and conical
armature; flat armature is used for short strokes, the conical one for strokes
approx. twice as great. Adaptation of the armature shape to
customer-specific applications is possible, for example for a decreasing solenoid force-stroke curve.
The initial position of the armature shaft must be determined at the time of installation, and the final position is limited in the magnet. The return of the armature shaft is generally made possible by an externally installed return spring.
Preferable nominal voltage 24 VDC, coils for many other nominal voltages are deliverable. In some cases connection to 230 VAC is possible by means of a bridge rectifier plug.
