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 light, 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 light (or block light) 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 time. Laser Beam Diameter: 3mm diameter infrared laser beam with high precise. LED Indicator Light: Equipped with LED induction indicator, NPN type, it will lights up when induction object. Working Methods: It uses the occlusion or reflection methods of the detected object to the speed of light, 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 light (or block light) can be detected.? Wide applications: it can be widely used in supermarket, assembly line, metallurgical industry, lift well and etc..
