A Photoelectric Sensor is an essential component in industrial automation, designed to detect the presence or absence of objects using a light transmitter and receiver. These sensors play a crucial role in various applications such as warehouse automation and machine guarding, ensuring efficient and safe operations.
What is the CMOS laser displacement sensor?
CMOS laser displacement sensor is a high-precision, non-contact measurement device that uses a laser beam and a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor to measure the distance to a target surface. These sensors are widely used in industrial automation and quality control where precise, real-time distance or thickness measurement is required.
