Overview
The Allen-Bradley 875C-M10NP30-A2 is a 3-wire DC capacitive proximity sensor designed for industrial automation and material detection applications. Featuring a shielded nickel-plated brass barrel with 30mm threaded diameter, this sensor delivers reliable detection of both metallic and non-metallic materials. Although discontinued in April 2021, the 875C-M10NP30-A2 remains in demand for legacy system maintenance and spare parts inventory.
Key Features
- Capacitive sensing technology – detects dielectric and metallic materials
- PNP source output (N.O.) – normally open configuration with micro QD (DC) connector
- 30mm threaded mount – standard industrial cylinder mounting
- Shielded construction – reduces false triggering and EMI sensitivity
- Built-in protection – short circuit, overload, reverse polarity, and transient noise protection
- 2–10mm sensing distance – adjustable sensitivity for precise target detection

Typical Applications
Capacitive proximity sensors are widely used in conveyor systems, packaging machines, assembly lines, and automated manufacturing environments. The 875C-M10NP30-A2 is suitable for detecting presence/absence, counting, and level sensing applications across food processing, automotive, pharmaceutical, and general industrial sectors. The plastic face and shielded design make it ideal for environments requiring minimal electromagnetic interference.
Compatibility & Replacements
The Allen-Bradley 875C-M10NP30-A2 was officially discontinued on April 9, 2021. Rockwell Automation’s direct replacement is the 875L-M16NP30-A2, which offers improved performance and extended lifecycle support. When sourcing this discontinued model, verify pin compatibility, voltage requirements, and output configuration with your control system before installation. Legacy units remain valuable for system maintenance and spare-parts provisioning in existing installations.
