Turck Inc. BI5-M18-LIU Inductive Proximity Sensor

Description:

The Turck BI5-M18-LIU inductive proximity sensor is used in industrial metal detection and analog position sensing systems. Commonly installed in material handling equipment, conveyor systems, machine tools, packaging machinery, and automated production lines requiring continuous distance measurement rather than simple on/off switching. Maintenance teams and system integrators use this part for replacement, retrofit, process monitoring, and automation system upgrades.

Applications:

The Turck BI5-M18-LIU is designed for contactless analog measurement of metallic targets in industrial automation environments. It is commonly used for position monitoring, level measurement, displacement sensing, and continuous feedback applications where a proportional analog output is required by PLCs, HMIs, or process controllers. Unlike standard proximity switches, the LIU series provides a linear output signal corresponding to target distance throughout the sensing range.
