RJ45 RJ11 Network Cable Tester Remote 300M | Vention Black KEFB0

The Vention Network Cable Tester (KEFB0) is a handheld RJ45 and RJ11 cable testing tool that detects open circuits, short circuits, and wiring faults in network and telephone cables across distances of up to 300 metres. It suits network installers, IT technicians, and structured cabling professionals who need a portable, accurate tool for verifying cable continuity and pinout configuration during installation, commissioning, and ongoing maintenance work.

The tester ships with a detachable remote unit that separates from the main body for long-distance testing, allowing one technician to work alone across a full cable run without a second person at the far end. Dual power support via 9V battery or Micro USB removes dependency on a single power source, and an onboard LED emergency light provides illumination in dark ceiling voids, equipment closets, and under-floor cable spaces during testing.
