Overview
The Allen-Bradley 872C-D4NP12-E2 is a 3-wire DC inductive proximity sensor designed for reliable object detection in industrial automation and control systems. This 12mm tubular sensor combines a nickel-plated brass barrel with cost-effective operation, delivering stable performance across machine control, material handling, and packaging applications.
Key Features
- 12mm Barrel Diameter: Compact tubular form factor fits standard M12 mounting locations
- 4mm Sensing Distance: Non-shielded design provides standard detection range for most industrial applications
- 3-Wire DC Configuration: +12/24VDC supply with independently sourcing output
- Normally Open (N.O.) Output: PNP source (M type) connection for direct controller integration
- 200mA Load Current: Supports relay coils and small logic circuits without additional drivers
- PVC Cable Connection: 2-meter cable with 5-conductor design for flexible wiring
