Photoelectric switch (photoelectric sensors) is the abbreviation of photoelectric proximity switch. It uses the occlusion or reflection methods of the detected object to the speed of , and the circuit is connected by the synchronous circuit to detect the presence or absence of the object. Objects are not limited to metal, detect all objects that reflect (or block ) can be detected. 

Features:
Elements: Selected quality elements, high sensoring sensitivity, with fine stability and durability.
ABS Lens: Diaphanous lens, made of ABS material, wear-resistant, scratch-resistant, and can provide long service .
Beam Diameter: 3mm diameter infrared beam with high precise.
Indicator : Equipped with induction indicator, NPN type, it will up when induction object.
Working Methods: It uses the occlusion or reflection methods of the detected object to the speed of , and the circuit is connected by the synchronous circuit to detect the presence or absence of the object. 
Applicable Object: Objects are not limited to metal, detect all objects that reflect (or block ) can be detected. 
Wide applications: it can be widely used in supermarket, assembly line, metallurgical industry, lift well and etc..
