Photoelectric sensors

Multifunctional sensor under a rugged “optics cover”

Your Benefits

  • Very good chemical resistance increases the service life
  • Control elements under the “optics cover” provide flexibility as well as best possible protection in the application and reduce the variety of devices and therefore storage requirements
  • Operational safety in ambient light and when devices are mounted opposite one another
  • Highest availability thanks to the very high operating reserve of the photoelectric sensors and through-beam photoelectric sensors
  • Assembly compatibility - DC devices and DC/AC devices available in the same design


Multifunctional sensor under a rugged “optics cover”

A distinguishing feature of the W34 product family is the rugged ABS plastic housing where all control elements are in a protected location under the “optics cover”. As a result, these sensors can also be used for outdoor applications. Especially for harsh and extreme ambient conditions, we recommend using the zinc die cast housing (W24-2 product family). The sensors are equipped with a minimum set of functions to reduce the variety of devices and consequently the storage requirements. Furthermore, this device design comes in DC and DC/AC variants. The W34 product family includes photoelectric proximity sensors with background suppression, photoelectric retro-reflective sensors, and a through-beam system. The photoelectric proximity sensors are characterized by their high precision at long distances as well as their high ambient light immunity.
