Overview
The Turck BI8-M18-RP6X-H1141 is a compact inductive proximity sensor designed for metal object detection in industrial automation applications. With an 8mm rated sensing distance and flush-mount M18 barrel housing, this sensor delivers reliable, contactless target detection using a high-frequency electromagnetic field. The cylinder detects ferrous and non-ferrous metals without wear, making it ideal for positioning control, counting, and part inspection in space-constrained environments.
Key Features
- 8mm sensing distance with flush-mount M18×1 threaded barrel for easy integration
