TA502A Wire Locator System – Find & Test LAN and Phone Lines Fast

The TA502A Cable Finder is a professional-grade wire locating and continuity testing system designed for network technicians, IT professionals, and electricians. Compatible with RJ45 LAN cables and RJ11 telephone lines, it transmits a signal up to 3km, making it ideal for tracing cables through walls, ceilings, floors, and large commercial installations. The split transmitter/receiver design keeps operation intuitive and flexible, whether you're working solo or with a partner.

Made in Mainland China.

Key Features

Simple One-Button Operation: Insert your RJ45 or RJ11 cable into the transmitter port, press SCAN to activate line search, then press and hold the receiver button — a beep confirms the target line is found.
Continuity Testing: Press TEST to activate the line calibration function. LED indicator lights on both transmitter and receiver instantly reveal connection issues, short circuits, open circuits, or crossovers.
Alligator Clip Adapter: For two-core telephone lines or bare conductors, the included alligator clip adapter connects to the RJ11 port. Indicator lights identify polarity — light 1 means red clip is negative/black is positive; light 3 reverses the polarity.
Wide Cable Compatibility: Works seamlessly with RJ45 network cable interfaces and RJ11 telephone line interfaces, plus bare wire via alligator clips.
Up to 3km Signal Range: Powerful signal transmission lets you trace long cable runs in large buildings, data centers, or outdoor installations.
Built-In Flashlight: The receiver includes an illumination light for working in dark spaces like server rooms or cable conduits.
Adjustable Sensitivity: Sensitivity adjustment range of 0–5 cm allows precise cable identification in dense cable bundles.
Split & Integrated Design: The units can operate separately for remote cable tracing or be combined for a compact, unified tool.
