Product description

The Allen Bradley 42KL-U2TC-A2 is a miniature retro-reflective photoelectric sensor designed for reliable object detection in compact industrial applications. It offers a sensing range of up to 10 meters and utilizes a polarized beam to prevent false triggering from shiny surfaces. This model features an NPN output and a quick disconnect (QD) connector for simplified installation and maintenance.

This sensor is well-suited for use in automated machinery, packaging systems, and material handling where space is limited but reliable detection with a reflector is required. The polarized beam ensures consistent performance when detecting various object types, including reflective ones.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Allen Bradley 42KL-U2TC-A2. We provide high-quality, surplus components to help you maintain your automation systems cost-effectively and efficiently.

Frequently asked questions

How does the polarized beam on the 42KL-U2TC-A2 improve detection?

The polarized beam on the 42KL-U2TC-A2 sensor helps to filter out reflections from shiny objects and the reflector itself, ensuring more reliable detection of targets by differentiating them from the background or the reflector.
