LIHTNE Wired Water Leak Detector Sensor Probe 12V – L-W10
LIHTNE Wired Water Liquid Leak Detector Sensor Probe – 12V DC
Stay one step ahead of costly water damage with the LIHTNE L-W10 Wired Water Leak Detector Sensor Probe. Designed for reliable, continuous monitoring in commercial and industrial environments, this fully isolated flood-detection sensor triggers an alarm the moment unwanted water is detected — giving you time to act before damage spreads.
Whether you're protecting a server room, communications base station, hotel utility space, library, warehouse, or precision machinery area, the L-W10 delivers fast, accurate detection through its dedicated integrated chip that amplifies, shapes, and compares impedance changes at the detection electrode. The result: instant dry-contact or high/low signal output the moment flooding is sensed.
Made in Mainland China.
Key Features
- High Sensitivity & Fast Response: Detects the presence of water rapidly for timely alerts, minimizing risk to equipment and property.
- Fully Isolated Design: Power supply, sensor input, and relay output are completely isolated (opto-isolated and transformer-isolated) for safe, interference-free operation.
- Integrated Fully Sealed Enclosure: Rugged, fully sealed plastic housing ensures long-term reliability in demanding environments.
- Selectable Output Modes: Relay output supports Normally Open (NO) or Normally Closed (NC) configuration — choose what works best for your alarm or control system.
- Expandable Detection: Main electrode features a spacer layer design; optional auxiliary electrodes can be added to broaden the detection coverage area.
- CE Certified: Meets CE safety and performance standards for peace of mind.

Frequently Asked Questions
Q: Can the LIHTNE L-W10 water leak detector work with a 24V DC system?
A: Yes. While the standard model operates on 12V DC, a 24V version is available. Simply leave a note specifying 24V when placing your order and the unit will be configured accordingly.
Q: What output modes does this wired water leak sensor support?
A: The L-W10 supports both Normally Open (NO) and Normally Closed (NC) relay output modes, selectable via the J1 jumper. It also provides high/low signal output, making it compatible with a wide range of alarm panels and control systems.
Q: How sensitive is the leak detector, and can I expand the detection area?
A: The sensor is highly sensitive and responds quickly to the presence of water at the probe electrode. The main electrode includes a spacer layer for precise detection, and optional auxiliary electrodes can be connected to extend the detection coverage area for larger spaces.
Q: Is the L-W10 water leak sensor suitable for outdoor use?
A: The L-W10 is designed primarily for indoor environments such as server rooms, utility spaces, and warehouses. Its operating range is 0°C–50°C and 20%–100% RH. While the enclosure is fully sealed, it is recommended for controlled indoor installations rather than direct outdoor exposure.
