Overview
The Allen-Bradley 871C-DT8NP18-D4 is a miniature small barrel inductive proximity sensor engineered for industrial automation and motion control systems. This sensor uses inductive sensing technology to detect the presence and position of ferromagnetic materials without physical contact, making it ideal for harsh manufacturing and assembly environments where reliability and precision are essential. The compact 18mm form factor allows for flexible mounting in space-constrained applications.
Key Features
- Miniature barrel design for compact system integration
- Inductive sensing technology for non-contact metal detection
- 18mm barrel diameter with standardized mounting interface
- Designed for industrial automation and positioning control
