Functional principle

Magnetic-inductive proximity switches are actuated by magnetic fields. They detect permanent magnets through non-ferromagnetic materials such as wood, plastic, non-ferrous metals, aluminum or stainless steel. Turck magnetic field sensors obtain a particularly high switching distance using the actuation magnets. As they are available in a number of sizes and versions, they enable a wide range of possibilities for detection, particularly in constructions where mounting space is limited or other difficult conditions prevail. The diagram shows a typical characteristic curve of the magnetic flux density [in mT] based on the distance in the axial direction and at room temperature.
