The slim body aesthetically fits in your equipment,since it is just 10mm thick.Both the receiver and the emitter feature job indicators,102mm wide,which use red bright LEDs.When the sensor output and the job indicator input are connected,the job indicator can be used as a large size operation indicator.With 20mm beam pitch (minimum sensing object Ø30mm)and sensing renge 5m,it can meet various needs.Setting different emission frequencies for two sensors together covers a wider detection area.The set frequencies can be identified by the number of emitting indicators which light up.
