Six-piece HDMI female-to-female coupler set

This pack contains six black HDMI female-to-female couplers that join two male-ended HDMI cables into a single longer run. Each unit measures 50 by 50 by 20 millimetres and weighs 20 grams. Gold-plated contacts preserve signal integrity across the connection. The couplers comply with the HDMI 2.0 standard and support resolutions up to 3840 by 2160 alongside 2560 by 1600, 2560 by 1440, 1920 by 1200 and 1080p.

Installers extending existing cables

The couplers suit home-theatre builders, AV integrators and anyone who needs extra reach between a source such as a games console, streaming stick or laptop and a display or receiver. They also enable Audio Return Channel, 3D video and 7.1 or 5.1 Dolby digital audio pass-through. Users who require an active signal booster for runs beyond passive cable limits, or who need a different gender combination such as male-to-female, should look at other adapter types.

HDMI 2.0 passive gender changer with 4K60 support

The decisive specification is compliance with the HDMI 2.0 standard, which allows 4K resolution at 60 hertz and the listed audio formats through a purely passive device. If the installation demands higher bandwidth such as 4K at 120 hertz or 8K video, an active repeater or fibre-optic extender will be required instead.

Questions about this item

How do I install the Advantech LST-HDMI-COUPER coupler, and what step do people often get wrong?

Connect one male HDMI plug into each female port of the 50 mm coupler; the step often missed is ensuring both plugs seat fully so the gold-plated contacts engage across all 19 pins.

What maintenance or replacement will the coupler need later?

No scheduled maintenance is required; if signal dropouts appear after many insertions, replace the individual coupler from the six-pack.

What limit shows up first under sustained 4K use?

The HDMI 2.0 link caps sustained throughput at the 3840×2160 60 Hz ceiling, so bandwidth is the first constraint.
