HT801A/B Network Cable Tester | PoE RJ45 RJ11 Line Finder

HT801A/B Multifunctional Network Cable Tester with PoE & LED Light

Take the guesswork out of network installations and cable troubleshooting. The HT801A/B Network Cable Tester is a professional-grade, all-in-one tool designed for IT technicians, electricians, and network installers. With support for RJ11 and RJ45 interfaces, it covers everything from basic continuity checks to advanced PoE power detection — all in a compact, handheld package.

Key Features

• Wire Finding & Cable Tracing: Locate and trace cables up to 3km through walls, floors, and conduit — works with shielded and unshielded cables.
• PoE Power Detection: Test and confirm PoE voltage levels directly from the receiver, so you know exactly what your network devices are receiving.
• Cable Pairing & Matchmaking: Quickly verify correct pin-to-pin wiring and identify crossed or miswired pairs in CAT5 and CAT6 cables.
• Crystal Head Compression Test: Confirm RJ45/RJ11 connector crimping quality in under 1 second — no more intermittent connections from bad crimps.
• NCV Non-Contact Voltage Detection: Safely detect live AC voltage without direct contact, with adjustable sensitivity and LED gear display.
• 60V Input Voltage Protection: Built-in protection keeps your tester safe when working on powered switches, routers, and telephone lines.
• Short-Circuit & Cable Break Detection: Pinpoint the exact location of faults in your cables — both breaks and short circuits.
• Red Light Pen (HT801B Only): Built-in visual fiber or trace indicator for additional cable identification tasks.
• Telephone Status Alert (HT801A Only): Audible and visual alerts for active telephone line status.
• LED Flashlight: Integrated LED torch for working in dark server rooms, under floors, or in cable trays.
• Auto Power-Off: Conserves battery life with automatic shutdown after 30 minutes of inactivity.
• Low Voltage Alert: Visual warning when battery power is running low.

Frequently Asked Questions

Q: What is the difference between the HT801A and HT801B network cable tester?

A: The HT801A includes a Telephone Status Alert function that provides audible and visual notification of active phone line status. The HT801B replaces this with a Red Light Pen for visual cable tracing and identification. Both models share all other core features including PoE testing, NCV, cable pairing, and LED lighting.

Q: Does the HT801A/B network cable tester come with a battery?

A: No, the battery is not included. The tester is powered by a standard 9V 6F22 battery, which is widely available at hardware and electronics stores. Both the transmitter and receiver require their own battery.

Q: Can I use this cable tester on a live network switch or router?

A: Yes. The HT801A/B features 60V input voltage protection, allowing it to safely trace cables connected to powered switches, routers, and telephone lines operating at or below 60V. Always verify your network equipment's operating voltage before testing.

Q: What types of cables are compatible with this network cable tester?

A: The tester supports CAT5 and CAT6 ethernet cables via RJ45 connectors, as well as telephone cables via RJ11 connectors. It works with both shielded and unshielded cable types during wire-finding and line-tracing operations.
