Product description

The Allen Bradley 42KL-RLB-A2 is a photoelectric sensor from the 42KL series, employing polarized retroreflective technology for reliable object detection. This sensor is designed to detect objects by sensing the reflection from a dedicated retroreflector, with the polarized beam minimizing false signals from shiny surfaces. It offers a robust sensing solution for various industrial automation needs.

This sensor is ideal for applications in manufacturing, material handling, and packaging where consistent and accurate detection of objects is required. Typical uses include verifying part presence on assembly lines, counting items on conveyors, or as part of machine guarding systems.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the Allen Bradley 42KL-RLB-A2, providing access to quality industrial automation components. We aim to deliver value and reliability, ensuring you can source the parts needed to keep your operations running efficiently.
