Functional principle

Inductive sensors detect metal objects

contactless and wear-free. For this purpose

they use a high-frequency electromagnetic AC

field that interacts with the target. The sensors

hosting a ferrite core coil generate the AC field

through an LC resonant circuit.

Special versions are available for ambient

temperatures between ‐60°C and +250°C.
