Product description

The Allen Bradley 42MRA-5000-FO is a photoelectric proximity sensor system that utilizes a separate fiber optic cable for sensing. This configuration allows the main sensor body to be mounted away from harsh environments, with the fiber optic cable providing flexibility in tight or demanding spaces. It features a normally open (NO) output.

This sensor is perfect for applications in high-temperature areas, corrosive atmospheres, or where space is extremely limited. Common uses include metal fabrication, welding environments, and precision assembly machines where remote sensing is critical.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the 42MRA-5000-FO to provide a robust sensing solution for challenging industrial settings.

Frequently asked questions

How does the Allen Bradley 42MRA-5000-FO fiber optic sensor work?

The 42MRA-5000-FO uses a separate fiber optic cable to transmit light to a target and receive the reflected light back to a main sensor body. This allows the main unit to be placed in a less demanding location, while the fiber optic cable handles sensing in tight or harsh spots.
