ABS housing E3JK-DS30C2 Diffuse type photoelectric sensor / switch output DC type NPN-NC
Photoelectric switch is a photoelectric proximity switch for short, it is the use of the object to be detected on the beam occlusion or reflected by the gating circuit, synchronous circuit, so as to detect objects without. Can be a photoelectric switch objects are not limited to metal, all reflect light objects can be detected. Photoelectric switch input current conversion injection into optical signals on the transmitter,receiver,and then according to the received light intensity and with or without detection of target objects. Photoelectric switch smoke alarm common security system, sports often use it to count the number of industrial mechanical arm.
