H-Tronic 1114505 Water Sensor with 30 m Cable

Monitor hard-to-reach areas for water leaks with this conductive water sensor from H-Tronic. The 30-meter cable lets you place the sensor head in basements, laundry rooms, or near heating systems while keeping the detector unit accessible. When the gold-plated probes come into contact with water or another conductive liquid, the resistance changes and triggers the connected H-Tronic water detector.

Why choose it

The long cable gives you flexibility to monitor distant or awkward spots without moving the main detector. Gold-plated probes resist corrosion and ensure reliable detection over time. The sensor is passive, so no separate power supply is needed—it draws power from the connected H-Tronic water detector.

Ideal use cases

• Leak detection in basements and cellars
• Monitoring laundry rooms and bathrooms
• Protecting server rooms and IT equipment
• Checking heating systems and boilers
• Detecting water in sumps, tanks, and on flat roofs

Good to know

The sensor head is rated IP68, making it suitable for submersion in water. It connects via a 3.5 mm stereo jack plug, which is compatible with several H-Tronic water detector models. The cable is PVC-insulated for durability.
