Leuze Sensor DMU430B-3000.X3/LTC-M12 Ultrasonic distance sensor

A robust M30-threaded ultrasonic sensor with a 3000 mm (3-meter) sensing range. It features a hybrid 4–20 mA analog current output and a PNP switching output, integrated with IO-Link for advanced diagnostics and remote configuration.

Description

The DMU430B-3000.X3/LTC-M12 is engineered for demanding industrial environments where long-distance, non-contact measurement is required. The “X3” designation indicates a standard straight-beam configuration, while the “LTC” suffix identifies its current-based output capabilities.

Using Time-of-Flight (ToF) technology, this sensor is particularly effective at measuring bulk material levels or large object positions. Because it relies on sound rather than light, it is unaffected by dust, steam, or the optical transparency of the target. The 4–20 mA analog signal is ideal for long cable runs in large facilities, as it is highly resistant to electromagnetic interference compared to voltage-based signals.

Features

  • Extended 3-Meter Range: Suited for large-scale applications like silo level monitoring, wide conveyor tracking, or vehicle positioning.
  • M30 Metal Housing: The nickel-plated brass body provides superior mechanical durability and a larger transducer face for a stable acoustic beam over long distances.
  • LTC Hybrid Output: Provides a continuous 4–20 mA current loop for distance tracking and a PNP switching output for threshold/limit alerts.
  • IO-Link 1.1 Integrated: Enables “Smart Sensor” functionality, allowing for digital distance value transmission, remote parameter setting, and health monitoring.
  • Onboard Teach-In: Can be calibrated via the physical teach-in input or the IO-Link interface to define specific measurement “windows.”
  • Advanced Temperature Compensation: Since the speed of sound varies with air temperature, an internal sensor real-time-corrects the measurement to maintain accuracy across the full 3-meter span.
