The Ikon HDMI adapters offer a range of methods of interfacing and terminating HDMI format signals.
The HDMI-BB is a back-to-back adapter for use where the rear cable approaches directly from the rear (required depth 20mm plus mating connector). The HDMI-B90B is similar but has the rear connector set at a 90 degree angle for applications where the rear cable approached from the side (required depth 20mm). The HDMI-ST screw terminal adapter brings all the HDMI contacts out to screw terminals with minimal signal loss, and is designed for panel mounting applications (required depth 30mm).
All types share the same mounting profile, with tapped, M3.5 threaded mounting posts at 25mm centres (as D-sub 9-way).
