Allen-Bradley 42EF-D1MNAK-A2 Diffuse Photoelectric Sensor

Allen-Bradley 42EF-D1MNAK-A2 PHOTOSWITCH diffuse photoelectric sensor delivers 500 mm detection with a 11-30 VDC supply, making it well-suited for inline sensing on conveyors, packaging lines, and assembly stations. As a diffuse-mode device, it detects nearby targets by reflected infrared light without physical contact, a setup that simplifies mounting in tight spaces and reduces alignment requirements compared with through-beam sensors. The unit is part of the PHOTOSWITCH family and ships with a 2 m (6.5 ft) cable for straightforward integration into control cabinets and machine wiring. Designed for DC operation, it supports standard industrial control schemes and can be used anywhere a compact, non-contact presence detector is needed within its 0.5 m sensing range. Common applications include verifying part presence on conveyors, detecting features during assembly, and controlling processes in packaging and manufacturing lines, where quick response and repeatable sensing are critical. This Allen-Bradley catalog entry reflects a diffuse sensor designed for industrial environments and compatibility with Rockwell Automation control architectures.
