The Light Curtain Sensor
II. Working Principle
A light curtain sensor is a safety protection device based on the photoelectric principle, capable of preventing personnel from entering dangerous areas and automatically detecting objects. Its basic working principle: at the transmitter end, an infrared LED light source emits multiple invisible beams; at the receiver end, each beam transmitted by the transmitter is received. When any one of the beams is blocked, the detector issues an alarm signal and outputs it, achieving object detection and personnel-entry safety protection.

III. Application Cases
01
Light curtain sensors on turntable loading/unloading equipment
A turntable loading/unloading device is a piece of equipment that continuously and evenly transfers materials from one station to another. When an operator enters the turntable's working range to load or unload materials, the light curtain sensor promptly detects the presence and outputs a signal, ensuring the turntable does not operate while personnel are inside — effectively protecting operator safety.
02
Light curtain sensors on automated stamping equipment
With a light curtain sensor installed on automated stamping equipment, when an operator intrudes into a working stamping machine, an alarm signal is promptly sent to the machine to stop it. This not only effectively prevents crushing, striking, rolling and other accidents to operators, but also ensures safe production while improving production efficiency. Installation and use are simple, it occupies little space, and it offers excellent cost-effectiveness.
03
Light curtain sensors on automated assembly equipment
After installing a light curtain sensor on an assembly production line, multiple parallel infrared beams form a safety wall protecting workers. Once a worker intrudes into the dangerous area, the machine immediately stops working to protect the worker's safety.
04
Light curtain sensors on automated cutting equipment
When cutting plates, the cutting machine operates at a very high speed. With a light curtain sensor installed, once an object blocking the infrared beams of the light curtain sensor is detected, the entire cutting machine immediately stops working to protect the operator's personal safety.
05
Light curtain sensors on automated assembly equipment
Installing a light curtain sensor on assembly equipment in an automated production line can, to a certain extent, reduce the risk of injury to operators during machine operation. Combined with the equipment control system, the machine can automatically stop in dangerous situations.
