Network Cable Tester with RJ45 and RJ11 Adapters, LED Flashlight

Track Network Cables Faster with This Circuit Breaker Finder

You're tracing cables through a wall and can't tell which one goes where. You're testing connections one by one, wasting time on guesswork and wrong turns. This tester helps you identify network and telephone lines quickly during installations, repairs, or system upgrades.

The receiver plugs into RJ45 network jacks or RJ11 phone jacks and sends a signal down the line. The transmitter picks up that signal and shows connection status through sequence lights and audio tones. You adjust the volume on the included earphone to hear feedback clearly in loud spaces.

It tests both network and telephone cables through dedicated RJ45 and RJ11 adapters. The sequence lights show polarity and connection order when you run tests. The crocodile clips attach to bare wires for DC level detection and electrode testing.

The built in LED flashlight lights up dark crawl spaces, ceilings, or server racks while you work. The manual switch toggles between testing modes and activates the proofreading function for line verification. The single button operation keeps things simple when you're holding cables and tools at the same time.

• DUAL INTERFACE TESTING: Works with RJ45 network cables and RJ11 telephone lines through dedicated adapters for each connection type.
  
  
• DC POLARITY DETECTION: Identifies positive and negative electrodes on bare wires using crocodile clips and sequence light indicators instantly.
  
  
• ADJUSTABLE AUDIO FEEDBACK: Included earphone with volume control delivers clear tone signals when testing cables in noisy work environments.
  
  
• SEQUENCE LIGHT DISPLAY: Shows connection order and cable status through visual indicators that confirm proper wiring and line continuity.
  
  
• INTEGRATED LED FLASHLIGHT: Bright light illuminates dark spaces behind walls, under floors, or inside equipment racks during cable tracing.
  
  
• PROOFREADING MODE: Verifies network cable integrity by checking each wire in sequence and confirming correct termination at both ends.
  
  
• CROCODILE CLIP ADAPTERS: Attach to exposed wires for testing power lines, speaker cables, and other connections beyond standard network jacks.
  
  
• SINGLE BUTTON OPERATION: Manual switch controls testing modes and flashlight function without complicated menus or multiple button combinations.
