Series 25

Compact, reliable, cost-effective

Series 25B offers a high level of flexibility. All operating principles – from the throughbeam photoelectric sensor to the scanner with background suppression – are optimised for the different applications. Protection classes IP 67 and IP 66 as well as active ambient light suppression enable use in a wide range of industrial sectors. A number of different options, such as activation input or warning output, facilitate a high level of process reliability and, thus, system availability.

Advantages and benefits at a glance:

  • With brightVision®: Fast and easy alignment through the use of a very bright light spot; bright, 360° visible indicator diodes facilitate full control;
  • With an additional status display on the front side of the sensor (scanner with background suppression);
  • Insensitive against soiling due to very high performance reserve;
  • Robust, compact housing;
  • Low ambient light sensitivity through A²LS;
  • High resistance to environmental influences: IP 67, IP 66;
  • Large operating temperature range: -40°C – +60°C;
  • Increased availability through warning output and activation input.
