What is a Beam sensor?

A beam sensor is a type of sensor used for detecting objects or confirming positions. It uses light or lasers to sense the distance to a target or the presence of an object. The sensor works by having a transmitter and a receiver pair, where the light beam is reflected by an object and reaches the receiver. When the beam is interrupted by an object, the sensor sends a signal to trigger an action. Beam sensors are capable of non-contact object detection, providing high accuracy, reducing machine failure, and offering efficient control. They are widely used in logistics, manufacturing, and security systems.

Application of Beam sensor

✅ Object Detection on Production Lines
In manufacturing production lines, beam sensors are used to confirm that parts are correctly positioned on conveyor belts. By detecting the position of the objects, the sensor can manage the timing of machine stops and transitions to the next process.
✅ Intrusion Detection in Security Systems
Beam sensors are installed in security systems around fences or doors to detect intruders when they interrupt the beam. This method allows quick detection of intrusions and triggers alarms.
✅ Automated Sorting Systems in Logistics Warehouses
Beam sensors track the movement of goods in logistics warehouses, ensuring accurate sorting. When the beam is interrupted by an object, instructions are sent to proceed to the next step, facilitating efficient sorting operations.
✅ Automatic Door Opening and Closing Detection
Beam sensors placed near automatic doors detect when a person approaches by interrupting the beam, causing the doors to open automatically. This method is touchless and hygienic.
