Extron HDMI Ultra/3 (part number 26-663-03) — a 3 ft (90 cm) Premium High Speed HDMI cable, the workhorse length of the HDMI Ultra Series.

Three feet is enough to leave a switcher, cross a rack bay and land on a scaler or extender with a service loop intact. Extron builds the run from its own 28 AWG conductor set, so the finished cable is thinner and far easier to dress than commodity HDMI. Double shielding under a fluorocopolymer tape binder and tinned copper braid keeps the four data pairs clean, and the pairs hold 100 ohms ±10 ohms across the band that a 4K signal actually occupies.

Where It Is Used

Rack patching between matrix switchers, scalers and streaming encoders; classroom lecterns; digital signage cabinets; and imaging or control room consoles where several sources share a single equipment bay and cable bulk quickly becomes the limiting factor.
