ST Sensor 871TM-BH8N18-A2 - Proximity Sensor

The 871TM-BH8N18-A2 is a high-performance proximity sensor built for reliability in tough industrial environments. With a rugged stainless steel housing and durable metal sensing face, it stands up to heavy-duty use where plastic-face sensors may fail.

This 2-wire AC/DC sensor supports a wide voltage range (20–250V AC/DC) and delivers a normally open (N.O.) output, ideal for seamless integration with PLCs and control systems. Its 8mm sensing distance, 18mm barrel size, and unshielded design offer flexible installation options, especially where space is limited or shielding isn't required.

Whether you're automating machinery, detecting metal objects, or upgrading existing sensors, the 871TM-BH8N18-A2 offers proven performance and durability.

Key Features:

• Robust stainless steel body with metal face for demanding environments
• 8mm sensing distance for reliable object detection
• 2-wire AC/DC operation (20–250V), PLC-compatible
• Normally Open (N.O.) output
• Unshielded, 18mm diameter barrel
• PVC cable (2 conductors) for easy wiring
• Also available in 5mm sensing distance
