The safety light curtain sensor is a type of photoelectric safety protector (also known as safety grating sensor, punch protector, infrared safety protection device, etc.) installed on some potentially dangerous mechanical equipment

The grating consists of two parts: a projector and a receiver. The projector emits modulated infrared light, which is received by the receiver, forming a protective net. When an object enters the protective net and light from it is blocked by the object, the receiver circuit immediately responds by outputting a signal in the output section for emergency braking of machine tools such as punches and presses.

The safety light curtain sensor is a safety protection device that ensures the normal operation of equipment while ensuring the safety of workers' operations;
