Kramer CA-HM Active High Speed HDMI Cable – 4K 60 Hz over Long Distances

Kramer CA-HM is an active HDMI cable with Ethernet, designed to deliver stable HDMI signals over long cable runs where standard passive HDMI cables are insufficient. Thanks to built-in signal equalization and active compensation, the cable supports up to 18 Gbps and 4K UHD at 60 Hz (4:4:4) for lengths up to 20 meters.

The active electronics are integrated directly into the connectors, and the cable is powered entirely by the HDMI source, meaning no external power supply and a true plug-and-play solution. This makes the CA-HM particularly suitable for professional AV installations, conference rooms, educational environments, and fixed installations in walls or cable ducts.

The cable is equipped with Kramer's exclusive K-Lock HDMI connectors, which secure the cable with up to 6.8 kg (15 lbs) of retention force, minimizing the risk of accidental disconnections. A built-in LED indicator clearly shows when the signal is being transmitted correctly.
