FNIRSI WD-01 localizador de cabos com LCD de 2,8 polegadas, 125 kHz, CAT III 300V, até 2 m de profundidade

Electricians tracing live circuits, network technicians mapping buried lines, and maintenance crews locating hidden pipes all face the same challenge: finding cables without damaging walls or digging blindly. The FNIRSI WD-01 cable detector solves this by pairing a transmitter with the target cable and sweeping the receiver along the path. The receiver's 2.8-inch colour LCD shows real-time signal strength, while adjustable sensitivity lets you pinpoint the exact location, depth, and even breaks. With transmitter protection up to AC 250V and CAT III 300V safety rating, you can safely connect to live power lines. Rechargeable lithium-ion batteries in both units keep you working without constant battery swaps.

Why choose it

The WD-01 combines a clear colour display with robust voltage protection, making it safe for live circuit tracing. Its adjustable sensitivity and auto power off help you work efficiently without draining the battery. The lightweight, compact design fits easily in a tool bag, and the rechargeable batteries reduce long-term costs.

Ideal use cases

• Tracing live or dead electrical wiring inside walls before drilling
• Locating underground cables or pipes for excavation projects
• Identifying cable breaks or faults in long runs
• Mapping network or communication cable routes in buildings
• Finding metal pipes in walls or under floors

Good to know

The transmitter outputs a 125 kHz signal that the receiver picks up, allowing you to follow the cable path. Auto power off is adjustable, so you can set it to conserve battery when not in use. The device is rated CAT III 300V, meaning it can be safely connected to circuits in fixed installations, such as distribution boards. Always follow local safety regulations when working with live circuits.
