All metal sensors
Factor 1 inductive sensors switch with the same switching distance without reduction factor for different metals. Proximity sensors are based on the proven inductive principle - switches con tactless when metallic objects come close due to the inductive dampening of a resonant circuit.
Factor 1 sensors are used where different metals from steel to aluminium should be detected. They are, for example, used for the occupation control of presses, where different metals are used.
