Object detection of the first rank

Reliably detecting the smallest details has always been a major challenge. This is where our new sensor demonstrates its class-leading performance. The BOS 21M photoelectric High Precision Laser sensor from the product family of diffuse sensors with background suppression, impresses with outstanding precision in all detection tasks and displays numerous useful additional features.

Different detection and processing modes enable you to detect even complicated objects with exactness. When other sensors reach their limits, the laser precision sensor handles even complex applications with aplomb.
Two different sensor modes can be selected:
In background suppression mode the sensor is taught for the object to be detected, which is then detected with high precision.
In background processing mode the background is learned. Objects in front of the background are detected. This means the BOS 21M HPL reliably detects highly reflective or shiny parts.

Thanks to these two sensor modes you always achieve the maximum precision and reliability. Depending on the object you use IO-Link to simply switch over to the best and most reliable detection method for the task at hand.

If you are using the sensor in critical environments with much stray light, the intelligent ambient light suppression provides for even greater improvement. The sensor uses this function to reliably filter out interference and ambient light, so that false switching and the resulting equipment stoppage can be prevented.


  • Extremely precise object detection even in difficult conditions
  • Background suppression/background evaluation selectable
  • Intelligent data pre-processing in the sensor
  • Smart, efficient diagnostics
