Frequently bought together:



This area sensor of the BW series is another successor of Autonics’ area sensors. The tedious task of object sensing along with hits and trials and continuous human intervention has been reduced to almost negligible with this piece of technology. This sensor works in a way that it minimizes the non-significant area’s detection (the area which is not desired to be detected) making the desired sensing more stable and convenient. 

The BW20-44P has a quite decent range for area sensing (up to 7 meters). It can identify and distinguish between different perspectives of the target object, for example front view or the side view of an object is identified by high luminance twin operation indicator. It comes with a self-diagnosis function (reduced human intervention meaning less number of human and environmental errors). Also, the external diagnosis is also available in the sensor in case of self-diagnosis feature failure.   

Some Features of this product are given as under

  • It comes with an easy-to-use sensing technology (simple transmitting beam type sensing)
  • It gives an overall adequate sensing area (see details in the additional information)
  • It is durable and robust because of its waterproof IP65 rated structure (IEC standard)

Internal circuit’s protection is ensured by utilizing reverse polirty protection technique.
