Allen-Bradley 871TM-B5NP18-H2 Thermocouple Input Module

The Allen-Bradley 871TM-B5N18-H2 is a tubular stainless steel proximity sensor in Rockwell Automation’s 871TM family of tubular sensors. Its stainless steel housing and slender cylindrical form are designed for durable, compact metal sensing in industrial environments where space is tight and wiring routes are restricted. The B5N18-H2 variant represents a specific configuration within the 871TM lineup and is documented by Rockwell Automation in official catalogs and installation materials. This sensor provides noncontact detection of metal targets, making it suitable for applications such as sensing part presence on automated production lines, fixture monitoring, and other machine-automation tasks that require a small, rugged proximity device. As a Rockwell/Allen-Bradley product, 871TM-B5N18-H2 is listed in distributor catalogs and is supported by Rockwell’s product configurator and cut-sheet resources for the 871TM family.
