Long-range sensor with a metal housing for harsh environments

Your Benefits

  • Rugged metal housing that has passed IP 69K testing offers reliability and a long service life
  • Immune to ambient light and crosstalk, which improves detection security
  • Long-range retro-reflective and through-beam versions have a very high operating reserve, which ensures reliable operation even when if sensor is contaminated
  • Ensuring reliable operation in environments with temperatures fluctuation due to standard or high-power front lens heating (prevention and reduction of condensation water on the front lens)
  • Variants with DC voltage and universal AC/DC voltage provide installation flexibility


Long-range sensor with a metal housing for harsh environments

The W24 features a rugged metal housing that has passed IP 69K testing, which ensures reliability in harsh industrial conditions. These sensors are highly resistant to ambient light and offer a very long sensing range with a high operating reserve. As a result, there are optional a standard front lens heating or a high-power front lens heating versions, similar to automotive rear window defrost, for use in environments with extreme temperatures fluctuation. An alarm output option enables early detection of contamination, reducing downtime that results from contamination interruptions. Variants with DC voltage and universal voltage DC/AC and multiple connectivity options provide additional flexibility within the W24 family.

The sensors are conform with the 2G category for explosive zones, which enhances their range of applications even further.
