Allen-Bradley 871TH-BH8N18-A2 Temperature Transmitter

Allen-Bradley 871TM-BH8N18-A2 Metal Face Inductive Proximity Sensor provides non-contact metal sensing in a compact 18 mm tubular housing with an 8 mm sensing distance, making it well-suited for inline detection on automated equipment. Designed as a 2-wire AC/DC (PLC Interfacer) device, it operates on 20–250 V AC/DC and delivers a normally open output for straightforward integration with control logic. The tubular stainless steel body with a metal face supports mounting in harsh industrial environments while maintaining repeatable sensing of metal targets within its 8 mm range. The model carries a temperature rating of -25 to +70 °C, enabling operation across typical factory floors and assembly lines. As part of Allen-Bradley/Rockwell Automation's 871TM family of metal-face inductive sensors, this 871TM-BH8N18-A2 emphasizes dependable proximity sensing in a compact form factor for conveyors, machinery, and packaging lines.
