Features: _x000D_ Photoelectric Switch uses the blocking or reflection of the detected object to the beam, to detect the existence of the object. _x000D_ Photoelectric Switch converts the input current into a light signal on the transmitter, and the receiver detects the target object according to the strength or presence of the received light. _x000D_ Objects are not limited to metal, and all objects that reflect light (or block light) can be detected. _x000D_ It uses infrared light to detect objects without contact or damages. _x000D_ High precision, quick response, strong anti-interference capability. _x000D_ _x000D_ _x000D_ Specification: _x000D_ Detection Range: 70cm10% _x000D_ Detection Range Adjustment: sensitivity regulator _x000D_ Detection Target: transparent/opaque object _x000D_ Response Time: 1ms _x000D_ On-delay: 1.5ms _x000D_ Light Source: infrared light 660nm _x000D_ Supply Voltage: DC12-24V(6-36V) impulse (P-P)
