Product description

The Allen Bradley 42KL-E1QZB-A2 is a photoelectric sensor from the 42KL Series, featuring polarized retro-reflective sensing. This technology effectively reduces false triggering from shiny surfaces. It uses visible red light for detection, with a sensing range of up to 7 meters when paired with a reflector. The sensor is equipped with an NPN output and a Quick Disconnect (QD) connector for convenient installation and maintenance.

This sensor is ideal for detecting objects in environments with challenging surfaces, such as detecting parts on metallic conveyors or differentiating between similar-looking items. It is widely used in automotive manufacturing, packaging, and material handling systems.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the 42KL-E1QZB-A2. We are dedicated to providing reliable and affordable industrial automation solutions.
