F07Harnesses & connectors

Carry power, commands, and data between assemblies.

Manufacturers & products

Source qualified wire and connectors or a complete terminated, tested harness. Product families may include lab and flight versions: the full screening code, wiring standard and configuration matter.

These are sourcing candidates, not a confirmed Starlink supply chain.

Product scope & qualifications
  • Connector supply does not necessarily include a complete harness.
View product & inquiry route

What remains unverified

  • Harness price and delivery require a wiring list, lengths and test requirements.
  • Contact addresses do not establish the origin of wire, contacts or final assemblies.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Circuit topology & pinout

    Specify power, signal, coaxial and high-speed circuits in a wiring schedule.

  • Current & voltage ratings

    Check simultaneous loaded contacts, temperature rise, wire gauge and derating.

  • Signal integrity

    Compare impedance, insertion loss, crosstalk and skew at the actual rate.

  • Cable construction

    Define conductor gauge, insulation, shields, radiation and outgassing requirements.

  • Connector size & retention

    Compare pitch, contact count, mating cycles, locking hardware and access.

  • Mass & routing

    Include backshells, strain relief, bend radius and service loops.

  • Temperature & vacuum

    Request evidence for every material and the finished assembly.

  • Shielding & grounding

    Specify termination and bonding intent rather than relying on a cable name.

  • Screening & acceptance

    Distinguish lab, engineering-model and flight ordering codes.

  • Assembly tests & traceability

    Request continuity, insulation, dielectric and high-speed test reports.

Selection & integration notes
  • Single-contact maximum current may exceed the limit when all contacts are loaded.
  • Lab and flight SpaceWire assemblies can share a product name but differ in screening.
  • A custom space-qualified cable is not necessarily the general-purpose configuration in an online store.
