Diffuse Reflective Photoelectric Sensor

Diffuse reflective photoelectric sensor consists of light projector and light receiver in one, can distinguish transparent or opaque reflective object. The supply voltage is DC 12V-24V (6-36V) or AC 110V-220V (90-250V). Infrared photoelectric sensor can be compensated for longer distance with sensitivity controller, less susceptible to interference, fast reaction, long life, high resolution and high reliability.

Overview

Diffuse reflective photoelectric sensor with reverse power protection, short circuit protection, current overload protection, can be directly connected with PLC.

Applications: Photoelectric sensors have been used as position detection, liquid level control, product counting, width discrimination, speed detection, fixed length cutting, holes recognition, signal delay, automatic door sensing, color scale detection, punching and cutting Machine and security and many other areas. In addition, using the stealthiness of infrared, photoelectric sensors also can be used as a burglar alarm in banks, warehouses, shops, and offices.

Tips: Detection distance of diffuse reflection photoelectric sensor
The effective detection distance of the diffuse reflection photoelectric sensor is determined by the reflection ability of the detection object. The specific influencing factors are the distance between the detection object and the photoelectric sensor, the color, the size, the surface structure and the surface inclination of the detected object.
Through adjusting the potentiometer or mechanical adjustment knob in the photoelectric sensor, to improve the receiving sensitivity for reflected light. In the case of a fixed detection distance at the scene, if there is a strong reflected light background. In order to avoid photoelectric switch malfunction, it's better to use a background suppression diffuse photoelectric sensor. Or directly keep away from the background, remove the background, paint the background to be matt black, make the background to be rough or gray and other methods to eliminate bad effect.
