PM photoelectric sensor

  • PM photoelectric sensor

U-shaped type microphotosensors

This series is only available until March 2017! Please use the successor products from our PM-25/45/65 series.

Not only their small size, but also the 17 different sensor shapes mean flexibility, space savings and quick installation on machinery. PM sensors are alternatively available as a cable type or as a crimp-connector version. They are equipped with two independent transistor outputs for light ON or dark ON operation.
