Introduction:
- Background suppression photoelectric sensor is a diffuse reflection sensor, which can only detect objects within its sensing range while avoiding the influence of the background.
- Compared with the common diffuse photoelectric sensor, the background suppression sensor is able to work effectively in application environments with a strong reflected light background, avoiding false operation caused by background reflected light.
- Our miniature background suppression diffuse photoelectric sensor is very compact and detection distance is 10-300 mm adjustable by a knob at the top of this product. Here below is the dimension of it:
- It uses 660 nm visible red light to detect the presence of an object, easy to calibrate the detecting point.
- Output is available in 3-wire PNP NO, PNP NC, or NPN NO, NPN NC(What is the difference between PNP and NPN sensor? See our article:PNP VS NPN Sensor: The Ultimate Showdown – Which One Wins?), its light emitter and receiver are integrated in one product.
Where you can use this sensor:
- Automatic assembly line product counting: On the assembly line, by installing background suppression bar-shaped photoelectric switches, bar-shaped objects can be detected and counted. For example, on the bottle production line, the number of bottles can be counted by installing photoelectric switches on the bottle caps.
- Â Positioning and sealing of packaging materials: In packaging machinery, background suppression photoelectric switches can be used to detect the position of packaging materials to accurately control the position and time of sealing.
- Detection and control of material height: In the automated production line, the background suppression bar photoelectric switch can be used to detect the height of the material and realize the control of the material flow.
