Turck BI8-M18-LIU-H1141 1535561 M18 inductive sensor

Industrial sensing

The Turck BI8-M18-LIU-H1141 is a flush-mount inductive sensor built for industrial automation tasks that require continuous position feedback. Its threaded M18 × 1 brass barrel installs directly into machine frames, while the M12 × 1 male connector provides a secure, vibration-resistant link to control cabinets. Engineers specify this unit when a discrete on-off signal is insufficient and an analog representation of target distance is needed.

Thermals noise power

The sensor operates from a 15 to 30 VDC supply and draws only the current required by its internal signal conditioning, so heat generation remains minimal inside sealed enclosures. With no moving parts and a fully potted metal housing, acoustic noise is effectively zero, making it suitable for noise-sensitive production lines. The analog electronics deliver a stable 0 to 10 V or 0 to 20 mA output across the entire measuring range without external cooling.

Upgrade path

This model replaces two-wire proximity switches that only indicate presence or absence, giving programmers a proportional signal for closed-loop control. The jump is worthwhile when a process demands variable-speed actuation, thickness monitoring or precise end-position damping rather than simple go-no-go detection. Buyers who need a purely digital output or a larger sensing distance should consider alternative sensor types.
