MDT KNX Leakage Sensor

MDT Leakage Sensor – Reliable detection of water ingress in KNX systems

The MDT SCN-LSEN1.01 leakage sensor was specifically developed for the early detection of water damage in KNX systems . Thanks to its precise electrolytic AC voltage measurement, the sensor detects even the smallest amounts of conductive liquids and reliably protects against costly water damage – ideal for residential buildings, utility rooms, and commercial applications.

Key features

• Precise leak detection
  • Detects conductive liquids from a minimum detection height of only 1 mm .
  • Electrolytic AC voltage measurement for safe and long-lasting detection.
• Alarm and control functions
  • Integrated alarm channel for immediate forwarding of warning messages to the KNX system.
  • Visual alarm indication via a red LED directly on the sensor.
  • Adjustable on/off delay to adapt to different environments.
  • Automatic or manual reset of the alarm via KNX commands.
• Easy installation and flexible application
  • Suitable for floor mounting – ideal for use under washing machines, heaters or hot water boilers .
  • 1.4 m connection cable for flexible positioning.
• Robust construction
  • Protection class IP66 – dustproof and protected against powerful water jets.
  • Operating temperature range from -20 to +70 °C for diverse application conditions.

Technical details

• Measurement method: Electrolytic AC voltage measurement.
• Detection height: From 1 mm of liquid.
• Power supply: KNX bus, typical consumption < 0.3 W.
• Dimensions: Ø 70 mm × 24 mm.
• Connection cable: 1.4 m KNX cable.
• KNX specification: TP-256, compatible with ETS 5 and ETS 6.
