Abstract
An electromagnet and plunger assembly including a ring-shaped solenoid coil having a fixed pole component which extends from the one end into the interior of the solenoid coil. Movable in the axial direction, the plunger extends from the other end into the interior of the solenoid coil. A control device serving the adjustment of the armature pull comprises a sensor element measuring the magnetic induction. The pole component is subdivided in two pole parts which are coaxially nested and between which an annular gap is formed. The annular gap is sealed with a magnetically nonconductive material on its end facing toward the plunger. The sensor element is located in the annular gap in the interior of the solenoid coil.
