Kurth Electronic KE 701 Testador de cabos de rede com gerador de tom, RJ45/RJ11/Coax, proteção 240V

With voltage protection up to 240V AC/DC, the Kurth Electronic KE 701 lets you safely test live network lines without fear of damage. This compact handheld tester verifies RJ45, RJ11/12, and coaxial cables, detecting opens, shorts, cross pairs, split pairs, and shielding faults. A built-in 1 kHz tone generator and included remote unit make cable tracing and identification straightforward, whether you're working on patch panels, wall outlets, or long cable runs.

Overview

The KE 701 is a versatile cable tester designed for installers, network technicians, and maintenance staff who need quick, reliable verification of common copper and coax cabling. It supports UTP and STP twisted-pair cables with RJ45 and RJ11/12 connectors, plus coaxial cables via the included F-connector adapter. The remote unit allows one-person testing of installed links, while the master unit's LED wire map display gives instant pin-to-pin status. Powered by a single 9V block battery (6LR61), it features auto power-off to conserve battery life and a robust, impact-resistant housing for daily field use.

What stands out

• High-voltage protection up to 240V AC/DC prevents damage when accidentally connected to live circuits.
• Tests RJ45 (UTP/STP), RJ11/12, and coaxial cables with F-connector adapter – one tool for multiple cable types.
