BWM Series - Through-beam Mapping Sensors

BWM Series Through-beam Mapping Sensors

The BWM series mapping sensors are optimized for ultra thin glass substrate detection with low levels of light reflection using double scan method. Users can install the sensors easily with a variety of functions. Users can set light reception levels to minimize the effects of defused reflection. The sensors support CC-Link and EtherCAT communication protocols.
