Overview
The Allen-Bradley 871C-N10A30 is a tubular inductive proximity sensor built for precise, non-contact detection of metallic objects in manufacturing and process control environments. This Series A sensor provides dependable performance in confined spaces where standard sensors cannot fit. The compact form factor and quick response time make it ideal for high-speed automation applications, conveyor systems, and position feedback loops.
Key Features
- 10mm Sensing Distance – Detects metallic targets up to 10 mm away, suitable for tight machine geometries
- 10–30 VDC Operating Voltage – Compatible with most industrial 12 VDC and 24 VDC control systems
- Fast Response Time – Typical 1 ms switching speed for high-speed production lines
- Compact Tubular Design – Space-saving form factor fits in confined mounting locations
- N.O. / N.C. Output Options – Flexible wiring configurations for different control architectures
- Mini Quick-Disconnect Connector – Simplifies installation and replacement without rewiring
