The sensors are divided into diffuse reflection type, feedback reflection type and opposite reflection type. They are used together with PLC programmable controller, single chip microcomputer, non gate circuit electronic counter, solid state relay, small relay and other products. The transmitting type aiming target uninterrupted transmitting beam receiver converts the received optical energy into current and transmits it to the following detection line, which can filter out the effective signal and apply the signal..Package List:5 xInfrared Photoelectric Switch
