Introduction:
- Lorentzzi® background suppression photoelectric sensor is a diffuse reflection sensor, which can detect objects within its sensing range while avoiding the influence of the background.
- Compared with the common diffuse photoelectric sensor, this background suppression sensor can not only detect black objects, but also accurately distinguish the target object from the background in the presence of highly reflective background, avoiding false detection.
- 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 620 nm visible red light to detect the presence of an object, easy to calibrate the detecting point.
- Output is available in 4-wire PNP NO+NC, NPN NO+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.
Application Scenario:
- Automatic assembly line product counting: By installing background suppression photoelectric switches on the assembly line, objects of different colors can be accurately detected and counted, eliminating the impact of high background brightness or dark objects on counting accuracy.
- Packaging material positioning and sealing: In packaging machinery, background suppression photoelectric switches can be used to detect the position of packaging materials, allowing precise control of sealing location and timing.
