18 mm Metal General Purpose Sensors

Bulletin 42CM 18mm Metal Cylindrical General Purpose Sensors are intended for heavy duty industrial applications requiring an industry standard 18 mm cylindrical housing. Five possible modes of sensing include transmitted beam, diffuse, retro-reflective, polarized retro-reflective, and background suppression, allowing the 42CM to be used in a variety of complex applications. Outputs are short-circuit protected to provide continuous operation even under unexpected conditions.
