G18-3A1na/PA Retroreflective Photoelectric Sensor, 1m Sensing Distance M18 Infrared Photocell Switch

Product Description

G18-3A1NA/PA M18 cylindrical retroreflective photocell sensor, max 1m detection range. Available NPN NA / PNP PA output, IP67 metal housing, work with reflector for industrial non-contact object detection.

G18-3A1NA/PA retroreflective photoelectric sensor is M18 threaded cylindrical type. It works together with reflector plate. The sensor emits infrared beam and receives light reflected back from reflector. When an object blocks the light path, switching signal will be triggered. Sensing distance up to 1 meter. Two versions optional: NPN NA and PNP PA. Built-in potentiometer to adjust sensitivity conveniently on site. Compatible with PLC and other industrial control systems. Built-in reverse polarity and short-circuit protection circuit. Nickel-plated brass cylindrical housing with IP67 dustproof & waterproof rating, stable performance in dusty and humid factory environment. LED indicator for quick working status inspection. It is widely used for object counting, product presence detection, material passing monitoring on conveyor belts, packaging machinery, automatic assembly lines and logistics sorting equipment.

WORKING PRINCIPLE PHOTOELECTRIC SWITCH

The working principle of the photoelectric switch is that when the beam emitted by the emitter is blocked or partly reflected by the object, the beam receiver whereby makes a judgment and reacts.The working principle of the photoelectric switch is that when the beam emitted by the emitter is blocked or partly reflected by the object, the beam receiver whereby makes a judgment and reacts.
