The W280 family of photoelectric sensors includes three types – energetic proximity, retro-reflective and through-beam.

Ready-to-mount installation kits cable preconnected to the sensor include a mounting bracket and a reflector (for retro-reflective versions only). Other device options include rotatable plugs for space-restricted conditions and terminal chambers for individual wiring. This family is particularly well suited for door and gate applications due to its compliance with EN-61000-6-3.

Devices with potentiometer and light/dark switching provide application flexibility. In addition, these sensors are available in DC and AC/DC versions.


  • Visible red light
  • Light/dark switching (DC devices only)
  • Rotatable connector, cable connection or terminal chamber
  • Versions for 10 – 30 V DC or 24 – 240 V DC/AC voltage supply
  • AC/DC devices are compliant with EN61000-6-3 (electromagnetic interference for “residential, commercial and light-industrial environments”)
  • Stainless steel mounting bracket and P250 reflector (for WL280 only) are included in delivery
  • UL recognized
