Extron One USB-C Female to HDMI Female on Pigtail (part number 70-1243-12) — the black Flex55 half-size plate that feeds an HDMI display from a USB-C source running DisplayPort Alt Mode, at up to 4K/60 with 4:4:4 colour.

This is the Flex55 member of the family, not the MAAP one, and the difference is mechanical rather than electrical. The plate is plastic, measures 2.17" H x 1.08" W x 0.29" D, and mounts to Flex55 frames and enclosures — or to a EU junction box when a Flex55 mounting kit is used. Electrically it matches its MAAP sibling: HDMI 2.0b with HDCP 2.3, an 18 Gbps ceiling at 6 Gbps per colour, and EDID, HDCP and audio passed between source and display.

Key Capabilities

• Flex55 half-size Quick Connect plate — fits Flex55 frames, enclosures and EU boxes
• USB-C DisplayPort Alt Mode in, HDMI Type A out, EDID and HDCP passed through
• Up to 4K at 60 Hz with 4:4:4 processing; 18 Gbps maximum data rate
• Chroma sampling 4:4:4, 4:2:2 or 4:2:0 at 8, 10 or 12 bits per colour
• 13.5" (343 mm) pigtail; up to 12 ft (3.7 m) supported on input and output
• Supplies up to 1.1 watts on the HDMI port for active cables

Where It Is Used

Flex55 is Extron's format for EU-style back boxes and slim furniture openings, so this plate turns up in European boardroom tables, lectern faces, wall boxes and joinery where a full-size AAP or MAAP frame will not fit. The use case is the same everywhere: USB-C laptops meeting an HDMI display infrastructure.
