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

Description

The DMU418B-1300.X3/LTV-M12 is designed for precise, non-contact distance measurement. The “X3” indicates a standard straight-beam orientation, while the “LTV” suffix signifies its dual-function output: a linear 0–10 V signal for continuous tracking and a digital switching signal.

Built with IO-Link integration, this sensor is “Industry 4.0 ready,” allowing maintenance teams to monitor signal quality, internal temperature, and precise millimetric distance data digitally. Its ultrasonic nature makes it the ideal choice for detecting transparent objects (glass/plastic), liquid levels, or highly reflective metal surfaces that typically cause errors in optical sensors.

Features

1.3-Meter Mid-Range: Provides a balance between a powerful acoustic pulse and a compact M18 footprint, suitable for medium-sized containers and conveyor widths.
LTV Hybrid Output: Delivers a 0–10 V analog 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: Unlike the plastic 318 series, the 418B often utilizes a nickel-plated brass housing, providing superior mechanical durability in high-vibration environments.
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 and switching points.
