Free light path - clean air


Interrupted light path – contaminated air


Application: Air filter system - particulate matter detection


The state of an air filter is monitored with the aid of the ISD-2XC-IDX-OP retroreflective light barriers with teach-in function and a triple mirror (40mm). If the filter breaks, the retroreflective light barrier detects the dirt particles in the air.
