Rectangular Photoelectric Sensor, 25-120mm/100-350mm/5m

Square photoelectric sensors detect target presence by emitting a light beam and monitoring whether it is obstructed by an object. When light reaches the receiver, the sensor outputs a stable signal. When an object enters the light path and blocks the beam, the output state changes, enabling detection.

Rectangular photoelectric sensors are widely used in automated production lines, logistics conveyance, packaging machinery, electronics manufacturing, and access control systems. Their square housing facilitates mounting and is suitable for confined spaces or applications requiring lateral detection. Multiple detection modes—transmissive, reflective, and diffuse reflective—accommodate diverse target materials like cardboard boxes, metal parts, plastic bottles, and transparent objects.

The primary advantages of rectangular photoelectric sensors lie in their flexible mounting options, simplified alignment, and high mechanical strength. Compared to cylindrical sensors, the square structure is easier to secure to equipment mounts, preventing rotational misalignment. Its optical axis is typically more stable, making it suitable for applications requiring precise position control. The larger size also allows integration of more powerful light-emitting components or more complex circuitry, enhancing detection range and anti-interference performance. For equipment requiring side mounting or with limited space, square sensors are generally easier to wire and mount than cylindrical ones.
