Product Description

The Keyence PR-MB30P3 is a compact, self-contained photoelectric sensor designed for precise detection in tight spaces. With a detection range of 1 to 30 mm and a spot diameter of approximately 5.5 mm at 30 mm, it ensures accurate sensing of small objects. The sensor features two control outputs: Output 1 operates in Light-ON mode, while Output 2 functions in Dark-ON mode, both with fast response times. It is equipped with a 3-meter cable and is housed in a mini-slim body, making it ideal for applications with limited installation space. The PR-MB30P3 is built to withstand harsh industrial environments, offering high resistance to vibration and shock, and is compliant with IP67 and IP69K standards.​
