A light curtain sensor is a safety device commonly used in industrial automation to protect workers from hazardous machinery and ensure safe operation of automated systems. It consists of a transmitter and receiver that work together to create an invisible barrier of infrared light beams. When any object, such as a hand or body part, interrupts one or more of these beams, the system triggers an immediate response—typically shutting down the connected machine to prevent injury.

A light curtain sensor works by creating an invisible barrier of infrared light beams between a transmitter and a receiver. These beams form a “curtain” of light that monitors a specific area—typically near hazardous machinery or automation zones. When any object, such as a person’s hand, limb, or even a tool, breaks one or more of the beams, the system immediately sends a stop signal to the connected machine, halting its operation to prevent injury.

The light waves in the universe are only about 370nm to 760nm wavelengths visible to humans.

The working principle of the laser range measurement sensor is based on the time of flight ranging technology TOF (Time-of-Flight).

The laser displacement sensor is a measurement system composed of high linearity and tiny light spots, with up to 1536 micron-level linear CMOS photosensitive components as the reception.
