Laser Through Beam Photoelectric Sensor, 30m, NPN/PNP

A laser through-beam photoelectric sensor consists of an emitter and a receiver. When the laser beam emitted by the emitter is blocked by an object, the light intensity at the receiver decreases, causing the sensor to output a switching signal. Utilizing a laser beam provides a more concentrated light source with strong anti-interference capabilities, making it suitable for long-distance and high-speed detection.

Laser through-beam sensors utilize a laser light source, producing a smaller spot size with stronger directionality, enabling stable detection over distances exceeding several tens of meters. Standard through-beam sensors typically employ infrared LEDs, offering shorter detection ranges and being more sensitive to bright light environments. Laser through-beam sensors demonstrate significant advantages in precision, detection distance, and interference resistance.

Laser through-beam photoelectric sensors are widely used in logistics conveyance, packaging production, workpiece positioning, vehicle inspection, counting systems, high-speed sorting equipment, and industrial scenarios requiring reliable long-distance detection. They are particularly well-suited for detecting small objects, transparent materials, or high-speed moving items.
