CABLE SEARCHING DEVICE ACC. LEICA 850281 256HZ-200KHZ

Leica 850281 - 3.15" Signal Clamp – 256 Hz–200 kHz, 80 mm The Leica 850281 Signal Clamp is a professional accessory designed to safely and efficiently inject a tracing signal into a cable without direct electrical connection. It is intended for use with Leica DA signal transmitters as part of the Leica DD series cable locator systems (DD120, DD130, DD175, and DD300). The signal clamp operates inductively: the clamp is placed around the cable, after which the signal transmitter injects an active tracing signal into the cable through the clamp. Since no metallic contact with the cable is required, there is no need to strip the cable or make a direct connection. This makes the work faster and, above all, safer, especially when handling energized power cables or live supply lines. The Leica 850281 signal clamp has a jaw opening of approximately 80 mm (3.15"), making it an excellent solution for medium-sized power, telecommunications, and distribution cables as well as metallic pipe lines. This size offers a good balance between capacity and efficient signal transfer. Unlike fixed-frequency models, the Leica 850281 operates over a wide frequency range of 256 Hz–200 kHz when used with compatible Leica DA signal transmitters. The wide frequency range allows optimal frequency selection based on the target. Lower frequencies are suitable for long cable routes and reduce signal coupling to adjacent conductors, while higher frequencies improve coupling on short or discontinuous lines. In practice, the signal clamp is an excellent solution for applications where direct connection is not possible or should be avoided. Inductive signal transfer enables reliable and clear positioning signals when used together with a Leica DA transmitter. Structurally, the Leica 850281 is designed to withstand construction site conditions. The clamp is suitable for general power and supply cables, and its jaw opening allows use with cables up to approximately 80 mm in diameter. When the clamp is tightly closed around the cable and the transmitter is set to the appropriate frequency, signal transfer is efficient and accurate positioning is achieved using the Leica DD cable locator. The Leica 85081 Signal Clamp complements the DD and DA systems by providing a professional and safe method for injecting tracing signals. It improves work efficiency, reduces the risk of cable damage, and adds certainty to all underground infrastructure locating tasks.
