HDMI Cable Kramer Electronics CA-HM 20m

The Kramer Electronics CA-HM HDMI cable is a 20 m copper cable with HDMI Type A connectors on both ends, designed to deliver stable HDMI signals over long distances. It supports data rates up to 18 Gbps at 20 m and up to 10.2 Gbps at 30 m, 3D formats and Audio Return Channel (ARC). The connector draws power from the HDMI source, enabling plug & play operation without an external power supply, and includes a status LED that indicates successful signal transmission.

Advantages

The cable uses advanced equalizing and signal compensation in the connector to preserve signal integrity in Pro AV installations. It features Kramer’s K-Lock HDMI connector to prevent unintentional disconnection and gold-plated contacts for reliable contact and reduced corrosion. The built-in power draw eliminates the need for an external power adapter.

Suitable for

• Long-distance connections between AV sources and displays (up to 20 m at 18 Gbps)
• Professional AV installations where secure cable retention is required
• Setups that require 3D and ARC support
• Environments where plug & play operation without external power is preferred
