Description
The 42CS family of sensors offers a wide range of sensing
modes in a smooth 316L stainless steel housing, designed for
food, beverage and pharmaceutical applications.
The ferromagnetic teach feature makes the sensor easy to
program by simply placing a ferromagnetic metal object on a
section of the sensors housing to initiate the teach process.
The smooth and clean design minimizes the collection and
accumulation of undesired particles and allows for a fast
cleanup.
