Turck RU30-M18-LIX-H1141 Inductive Proximity Sensor

Turck RU30-M18-LIX-H1141 is an ultrasonic diffuse-mode sensor in a cylindrical M18 housing that provides a 4–20 mA analog output for direct integration into process control loops. It detects non-contact objects across a 5–30 cm range with a 6° acoustic cone, and is powered from 20–30 VDC via a male M12 x 1 connector. The rugged CuZn nickel-plated housing delivers IP67 protection and operates from -25 to +70 °C, with compact dimensions of Ø18 x 101 mm. Key electrical specs include a no-load current of ≤50 mA, load resistance ≤300 Ω, and built-in protections for short-circuit, reverse polarity, and wire breakage; it also supports synchronization for multi-device applications. The analog output is adjustable in range using the RU-PDI programming device, allowing the 4–20 mA signal to be matched to the desired measurement window. Typical applications include presence/absence checks on conveyors, level or distance sensing in packaging lines, and non-contact detection in environments with dust, moisture, or spray, where a continuous current-loop signal is advantageous. This RU30 family sensor combines a compact M18 form factor with reliable IP67 sealing for industrial automation tasks requiring a precise, continuous analog distance signal.
