Overview
The Allen-Bradley 872C-D10NP30-D4 is a WorldProx 3-wire DC inductive proximity sensor designed for reliable ferrous metal detection in industrial automation. This 30mm barrel sensor delivers consistent performance in machine guarding, part presence detection, and position sensing applications where space constraints require compact mounting.
Key Features
- 30mm tubular barrel design fits confined installation spaces
- 10mm sensing distance for close-proximity ferrous metal detection
- 10–30V DC supply range for flexible circuit integration
- PNP (source) output with normally-open switch logic
- Micro QD quick-disconnect connector for rapid installation and replacement
- Non-shielded design suitable for open-air mounting
Technical Specifications
Compact form factor and standard operating parameters make this sensor suitable for OEM equipment retrofits and new system integration. The 3-wire configuration minimizes wiring complexity while the Micro QD connection reduces changeover time during maintenance.
Typical Applications
- Material presence and position sensing on conveyor systems
- Machine safety interlocks and part-count verification
- Packaging and filling equipment guarding
- Hydraulic and pneumatic cylinder rod position detection
- Part detection in confined spaces requiring small-diameter sensors
