Overview
The Allen-Bradley 872C-D8NE18-D4 is a WorldProx™ series 3-wire DC inductive proximity sensor designed for non-contact detection of metallic targets in industrial automation systems. This 18mm tubular sensor operates from 10–30 V DC, providing an 8mm sensing range suitable for compact machine installations and assembly applications. With metal construction and an unshielded design, it delivers reliable performance in general-purpose industrial environments.
Key Features
- 18mm Barrel Diameter: Compact tubular housing fits standard M18 threaded openings
