The useful distinction

Recognize it. Then verify it.

FAKRA combines a coaxial interface with mechanically coded housings; a housing color is not a vehicle wiring diagram. [C366A]

Rosenberger lists cable, PCB and panel connectors, separate housings and cable assemblies within its FAKRA portfolio. [C366B]

Rosenberger lists 59S20X-400T5-y as a single right-angle PCB plug including housing; -y must be replaced by the requested coding. [C366C]

The Rosenberger coding table lists A, B, C, D, E, F, G, H, I, K, L, M, N and Z with corresponding color names. [C366D]

The Rosenberger code table notes that specific codings are available on request and that manufacturing may cause minor color differences. [C366E]

Rosenberger uses K for female/jack, S for male/plug and Z for plastic housings/accessories in its FAKRA number-code explanation. [C366F]

Rosenberger FAKRA manufacturer family: keying: Color-coded plastic housings with 13 distinct mechanical/color codes plus one neutral coding; coupling: Primary and secondary locks; impedance: 50 ohms, manufacturer-family feature; rf range: DC up to 6 GHz, manufacturer-family feature. Only the Rosenberger FAKRA manufacturer family feature table; no exact individual part properties or mating approval are established. [C366G]

The table retains manufacturer code letters and color names without assigning radio, GPS, camera or other equipment functions to an unknown vehicle.

Before you connect

What to check

  1. Identify the exact manufacturer, component role and ordering code.
  2. Check the required cable, interface, coding and equipment documentation independently.
  3. Do not trial-fit, rewire or infer a working connection from an illustration.
Trace a supported connection class →

A placeholder is not an exact part

In 59S20X-400T5-y, the final placeholder requires a coding choice. The catalogue-row drawing is not an exact ordered-code illustration or an approved PCB layout.
