Applications of sensor magnets
Nothing works without them: sensor magnets are essential components for reliably detecting positions, rotational movements or fill levels. In combination with reed switches, Hall or TMR sensors, they enable contactless switching operations and precise measurements – across a wide range of applications from automotive engineering to medical technology.

How sensor magnets work
Sensor magnets are the invisible heroes in countless applications – they provide the decisive magnetic field for the reliable operation of reed switches, Hall sensors and TMR sensors. But how exactly does the interaction of these components work?
The principle: magnetic field as a switching signal
Sensor magnets generate a defined magnetic field that is detected by various sensors:
1. Reed switches: These mechanical switches consist of two ferromagnetic contact reeds in a glass capsule. When a sensor magnet approaches, the reeds attract each other magnetically and close the circuit – contactless, wear-free and highly reliable.
2. Hall sensors: These semiconductor components measure the magnetic field strength and convert it into electrical signals. They are ideal for precise position detection and speed measurement.
3. TMR sensors (Tunnel Magneto Resistance): These sensors use quantum-mechanical effects to measure magnetic fields and offer maximum sensitivity with low energy consumption – perfect for demanding applications.
