HDMI female-to-female coupler MicroConnect KEYSTONE-HDMI — inline adapter for HDMI connections

MicroConnect KEYSTONE-HDMI is a female-to-female HDMI coupler designed to join two HDMI cables to extend a connection between AV devices. The compact inline adapter provides a straightforward mechanical and electrical join for HDMI runs, enabling continuity between TVs, monitors, projectors, receivers and set-top boxes without the need to replace existing cables. Its small form factor fits keystone and modular wall plate installations as well as inline cable joins in home and office environments.

Advantages

The coupler offers a simple way to extend HDMI cable length while preserving the HDMI connector orientation and signal path. It supports a compact installation footprint and is compatible with standard HDMI cable plugs on both sides, reducing cable waste and installation time. The device is maintenance-free and easy to insert or remove, making it suitable for temporary or permanent AV setups.

How to use

To use the MicroConnect KEYSTONE-HDMI coupler, align the male HDMI plug of the first cable with one side of the coupler and insert until fully seated. Repeat on the opposite side with the second HDMI cable. Ensure connectors are firmly inserted to maintain a reliable electrical contact and avoid excessive bending at the cable exit points. For wall plate or keystone panel installations, push the coupler into the keystone aperture until it snaps into place, then connect HDMI cables on either side.

Usage recommendations

For best signal integrity, use certified HDMI cables appropriate for the required resolution and length; avoid stacking multiple couplers in series and minimize cable bends near the connector to reduce strain. If high-bandwidth features (HDR, 4K@60Hz, or high refresh rates) are required, verify cable ratings and keep total cable length within manufacturer-recommended limits.
