Photoelectric sensors

Precise, durable and powerful solution for a wide range of applications

Your Benefits

  • Quick and easy commissioning due to a highly visible red PinPoint LED
  • PinPoint technology can replace laser photoelectric proximity sensors in some applications. No laser safety regulations and a longer operating life due to PinPoint technology
  • Resistant to ambient light, optical reflections, and crosstalk from other photoelectric devices
  • Less contamination due to high operating reserves, reducing downtime
  • Resistant to vibrations, reducing downtime
  • Operation in harsh environments with temperatures as low as –40 °C
  • IO-Link provides easy data access from the PLC
  • Quick and easy configuration


Precise, durable and powerful solution for a wide range of applications

The W27 family is designed for harsh industrial environments where it copes easily with heavy vibrations, shocks and extreme temperature fluctuations. The photoelectric proximity sensor is a leader in its class, especially through its reliable detection at long ranges. A sensor with PinPoint LED or a laser photoelectric proximity sensor is available for detection of small targets. The retro-reflective and through-beam versions reduce downtime due to high operating reserves. A diverse range of features further enhance application-specific functionality including, Teach or potentiometer adjustment, time delays, front lens heating, IO-Link, ASi, and universal voltage DC or AC/DC.
