HDMI cable ACT AK3870 0.5 m — HDMI Type A male to HDMI Type A male, HDMI 2.0, 18 Gbit/s, ARC, gold-plated contacts, black

The ACT AK3870 is a 0.5 m HDMI Premium High Speed v2.0 cable with HDMI Type A male connectors on both ends. It supports up to 18 Gbit/s bandwidth and 4K (3840x2160) at 60Hz with HDR, HDCP 2.2 compatibility, multi-channel audio and formats such as Dolby TrueHD and DTS-HD Master Audio. The cable features full copper conductors and gold-plated contacts for reliable signal transmission, a thin plate shield to reduce EMI/RFI, and a Low Smoke Zero Halogen (LSZH) jacket to limit toxic gas emissions in case of fire.

Advantages

The cable delivers stable high-bandwidth video and audio suitable for demanding 4K@60Hz sources thanks to its 18 Gbit/s capability and HDMI 2.0 support. Gold-plated contacts and full copper conductors improve connectivity and reduce signal loss. Thin plate shielding lowers electromagnetic and radio-frequency interference for use near sensitive equipment. The LSZH jacket increases safety in enclosed or public spaces by reducing smoke and halogen release in the event of cable damage.

Suitable for

• Connecting TVs, monitors and projectors to Blu-ray players, set-top boxes and media players
• Short high-speed HDMI runs between consoles, AV receivers and displays
• Medical imaging displays and other environments sensitive to EMI/RFI
• Data centres, control rooms and ship bridges where LSZH cabling is required
• Lecture halls, auditoriums and conference rooms requiring 4K presentation quality

When it may not be suitable

This 0.5 m cable is intended for short connections; it is not suitable where longer cable runs are required without active signal boosting. It also conforms to HDMI 2.0 (18 Gbit/s) and therefore does not provide the higher bandwidth features of HDMI 2.1 such as 4K at higher refresh rates or 8K support.

How to use

Connect one HDMI Type A male end to the HDMI output of your source device (for example a Blu-ray player, game console or set-top box) and the other end to the HDMI input of your display or AV receiver. Ensure both devices are set to the appropriate HDMI input/output and enable HDR or audio formats in device settings if required. For best performance keep the cable run short and avoid tight bends that may stress the cable.

What to consider before purchase

• Required cable length — this model is 0.5 m, suitable for short connections only
• HDMI version and bandwidth — HDMI 2.0 with 18 Gbit/s; does not support HDMI 2.1 features
• LSZH requirement — check whether low-smoke halogen-free cabling is mandatory in your installation environment
• Compatibility with device audio/video formats (HDR, HDCP 2.2, ARC)

Usage recommendations

Use the ACT AK3870 for short, high-quality HDMI links where 4K@60Hz, HDR and low-EMI operation are needed and where LSZH cabling is preferred for safety. Avoid using this cable for long runs without an active repeater or an HDMI 2.1 application requiring higher bandwidth.
