Slot-type limit photoelectric switch sensor (photoelectric switch proximity sensor) is actually a kind of through-beam photoelectric switch, also known as U-shaped photoelectric switch, which is an infrared sensor photoelectric product.
The slot photoelectric switch is usually a standard U-shaped structure, and its transmitter and receiver are located on both sides of the U-shaped slot, and form
An optical axis. When the detected object passes through the U-shaped groove and blocks the optical axis, the photoelectric switch generates the detected switching signal. The slot photoelectric switch is safer and more suitable for detecting high-speed changes and distinguishing transparent and semi-transparent objects.
It should be noted that the slot-type photoelectric switch has a four-wire output
The colors of the four wires are brown, blue, black, and white. These four wires are brown to +V power supply, blue to 0V, black and white are signal wires.
Photoelectric switches have been used for level detection, liquid level control, product counting, width discrimination, speed detection, fixed-length cutting, hole recognition, signal delay, automatic door sensing, color mark detection, punching and shearing machines, and Security protection and many other fields. In addition, the use of infrared concealment can also be used as an anti-theft warning in banks, warehouses, shops, offices and other occasions where it is needed.
