Leuze Sensor DMU418B-1300.X3/LTC-M12 Ultrasonic distance sensor

Description

The DMU418B-1300.X3/LTC-M12 is designed for precise, non-contact distance measurement. The “X3” indicates a standard straight-beam orientation, while the “LTC” suffix signifies its current-based output capabilities.

The 4–20 mA analog signal is the industrial standard for long cable runs, as it is highly resistant to electromagnetic interference (EMI) compared to voltage signals. Built with IO-Link integration, this sensor is “Industry 4.0 ready,” allowing maintenance teams to monitor signal quality and precise millimetric distance data digitally while the analog loop handles real-time control.

Features

1.3-Meter Mid-Range: Provides a powerful acoustic pulse in a compact M18 footprint, suitable for medium-sized containers and conveyor widths.
LTC Hybrid Output: Delivers a continuous 4–20 mA current signal for distance monitoring and a switching output for limit/threshold alerts.
IO-Link 1.1 Integrated: Enables “Smart Sensor” capabilities, including remote parameter cloning, digital distance values, and diagnostic “Signal Quality” feedback.
Metal Housing: The 418B series typically utilizes nickel-plated brass, providing superior mechanical durability and better heat dissipation than plastic alternatives.
Advanced Temperature Compensation: Automatically adjusts for air density fluctuations to ensure the measurement remains accurate ( $pm 1%$ ) even as factory temperatures change.
Teach-In Capability: Can be calibrated via a physical teach-in input or the IO-Link interface to define custom measurement windows.
