The autosen diffuse reflection sensor AO020 offers reliable position detection ranging from 1mm to 80mm. The red light detects objects of any size, shape and surface finish reliably and precisely. The sensor is light-on, i.e. it provides a switching signal when an object is detected. AO020 communicates with the master via IO-Link and the parameters can be set using autosen:io software.

The main strength of AO020 is its suitability for installation in confined spaces. The diffuse reflection sensor is characterised by its compact structural shape. The M8 connector can be routed out of the confined installation space with the integrated 30cm cable to facilitate installation. The three-wire cable is a PUR cable and, like the sensor, has a protection rating of IP67.

If you have questions regarding the IO-Link parameterization or want to use the parameterization service of autosen, please do not hesitate to contact us. Or start directly with the IO-Link starter kit ADS01.
