Product Description

The Keyence PZ-M72 is a compact M8 connector-type photoelectric sensor designed for precise detection in industrial automation applications. Featuring a multi-reflective sensing method, it offers a detection range from 20 to 900 mm using a 300 x 300 mm white matte paper target. The sensor utilizes an infrared LED light source and provides a response time of up to 1 ms, ensuring rapid detection. It supports both LIGHT-ON and DARK-ON operation modes, selectable via wiring, and includes visual indicators for output and stable operation. With a built-in sensitivity adjustment trimmer and robust environmental resistance, the PZ-M72 is ideal for applications requiring reliable and fast detection in compact spaces.​
