Photoelectric sensors
W2 Flat

Your Benefits

  • High-performance solutions for very tight spaces provide increased application flexibility
  • Fast response times with a high level of accuracy and precise switching points
  • The high enclosure rating and the rugged housing offer a long service life that withstands harsh environmental conditions
  • Quick and easy installation since sensors can be mounted directly on machine parts


The W2 Flat photoelectric sensor family is enclosed in a housing only 3.5 mm high, enabling it to fit in nearly all machine parts for reliable object detection. These sensors, which are one of the smallest photoelectric sensor families in the world, enable thin and compact machine designs. Their rugged housing includes metal-reinforced fixing holes that simplify machine integration. This flat design enables even a milling recess to be used to integrate the sensor safely in the machine.
