Through Beam Photoelectric Sensor, 0-0.5m/0-1m/0-1.5m

When installing a through-beam photoelectric sensor, ensure the transmitter and receiver are precisely aligned along the same optical axis. Failure to do so may cause detection instability. It is recommended to perform a rough alignment first, then fine-tune using the device's indicator lights or adjustment screws. Additionally, avoid direct sunlight on the receiver, strong light interference, or obstruction by other obstacles.

The through-beam photoelectric sensor consists of an emitter and a receiver. The emitter continuously emits an infrared beam, while the receiver detects whether the beam is obstructed. When the beam is unobstructed under normal conditions, the receiver stably receives the signal. When an object passes through and blocks the beam, the receiver signal immediately changes, thereby outputting a switch signal or analog signal to detect the object.

Due to their separate transmitter and receiver placement, through-beam sensors deliver strong, direct light energy. This design minimizes susceptibility to background color, object material, or reflectivity variations. Unlike diffuse or specular reflection sensors, through-beam operation does not rely on reflected light. Consequently, they maintain high stability and low false-trigger rates in dusty, smoky, or outdoor environments with intense sunlight, as well as over extended distances.
