The BWPK series area sensors feature a flat and compact body (10 mm) made of high strength PC/ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) plastic. Picking indicators on the emitter and receiver allow clear identification of job status. Installation and wiring is made easier with the removal of synchronization wiring. DIP switches are available to switch between various functions and modes including long/short sensing distance mode, mutual interference prevention function, Light ON/Dark ON switching and picking indicator ON/FLASHING options.
