RS PRO Retroreflective Photoelectric Sensor, Block Sensor, 150 mm → 10 m Detection Range

You can use this RS PRO retroreflective photoelectric block style sensor to detect and measure physical objects and quantities. It emits a beam of electromagnetic radiation that detects alterations in the return signal.
The sensor features a nickel-plated brass housing for resistance to wear and corrosion. The housing is made from polymethyl methacrylate (PMMA) and Acrylonitrile Butadiene Styrene (ABS) material to ensure it's strong, resistant to corrosion and lightweight. It has an Ingress Protection (IP) rating of IP67, which means it's protected against dust and temporary immersion in water.
You can adjust the sensing distance via a teach-in button. The sensor comes with reliable M12 lock nuts, so you have the elements you need for installation.
