Sensor device for detecting a magnetic field, and magnet-based sensor system for detecting a movement of a movable object

Abstract

A sensor device for detecting a magnetic field. The sensor device includes a Wiegand sensor unit and a Wiegand trigger unit. The Wiegand sensor unit includes at least two Wiegand wires and a coil arrangement which is arranged to radially surround the at least two Wiegand wires. The coil arrangement provides a sensor element and a trigger element which generates a trigger magnetic field. The Wiegand trigger unit includes a Wiegand wire and a sensor coil which is arranged to radially surround the Wiegand wire. A first end of the sensor coil of the Wiegand trigger unit is electrically connected to a first end of the trigger element of the Wiegand sensor unit, and a second end of the sensor coil of the Wiegand trigger unit is electrically connected to a second end of the trigger element of the Wiegand sensor unit.
