Description
The Allen‑Bradley 872C Series are industrial-grade inductive proximity sensors designed for reliable non-contact detection of metallic objects. These robust sensors feature threaded metal barrels (nickel-plated brass) with IP67 protection, making them suitable for harsh environments like machine automation, material handling, and packaging. The series includes various models differing in size (12 mm or 18 mm diameter), sensing distance, output configuration (2-wire AC/DC, N.O./N.C.), and connection type (cable or quick-disconnect). Known for their durability and precise switching, they are a staple in Rockwell Automation control systems.
