ECT 818018737 To Rosenberger FAKRA Jack Cable

The PCM-XY-0034-X cable connects four individual FAKRA plug leads to a single quad Mini Fakra module port. The module end uses an Original ECT 818018737 jack. Each branch ends in a Z Code FAKRA jack with a Rosenberger housing, so the assembly can mate with individual plug leads already fitted to a vehicle harness or bench fixture.

Four Dacar 302 coax leads carry the RF circuits separately. Each cavity in the quad jack has a dedicated path to one branch, with its center conductor and shield mapped on the assembly drawing. On a bench, this gives technicians access to one circuit at a time while the module connection stays in place.

Product Specifications

Connecting Four Plug Leads at One Module

Jack Branches for Plug Terminated Leads

The four branch jacks accept compatible FAKRA plug leads individually. This configuration fits a setup where the existing harness or fixture already ends in plugs. When selecting the assembly, check the mating face and part number of the existing connector. The water blue housing is a useful visual reference, while the interface and keying determine fit.

A Single Mating Point at the Quad Port

The ECT 818018737 jack groups four coax contacts in a single housing at the module. That puts the four module connections behind one latch while keeping them individually accessible at the branch end. When laying out a fixture, leave clearance above the red locking piece and behind the housing for the four coax leads to exit.

Separate Coax Leads for Separate Routes

The four leads leave the quad housing together and can be routed individually toward their mating plugs. This is practical when the plug leads enter a fixture from different positions or when a prototype harness has staggered connection points. During a fit check, measure along the intended cable path and allow room to handle each connector body.

The Cavity Number Identifies the Circuit

The branch jacks look alike, and their order can change as the bundle is routed. The quad cavity number gives each circuit a fixed reference. For example, cavity 4 connects to P2 on the drawing. If the branches are unlabeled, trace the center contact to identify the lead and check its shield path separately during continuity inspection.

Harness Integration and RF Bench Testing

Retain the Existing Harness Plug Ends

Use this assembly when the module has a compatible quad Mini Fakra port and the harness terminates in four individual FAKRA plugs. Confirm the mating connector part numbers and compare the module cavity assignments with the harness drawing before connecting the branches.

Check a Single Channel at the Fixture

Keep the quad jack mated to the module and access the circuit at its FAKRA branch. For a bench that uses its own channel names, match each fixture lead to the quad cavity number before testing. This makes it easier to trace a measurement back to the correct circuit when the assembly moves between fixtures.

Product Drawing

Product FAQ

What frequency range and impedance does the assembly have ?

The drawing specifies a nominal impedance of 50Ω, a frequency range from DC to 3GHz and a maximum VSWR of 1.800.

What mates with the four branch jacks ?

Each branch mates with a compatible FAKRA plug. Check the plug part number and keying against the Z Code jack before ordering.

Does this cable split a single RF signal into four outputs ?

The assembly carries four independent RF paths. Each cavity at the quad end connects to one branch jack through its own coax lead.

Does 59Z163-003-Z identify the full branch connector ?

59Z163-003-Z identifies the Rosenberger plastic housing used on each FAKRA jack. PCM-XY-0034-X identifies the complete cable assembly.

What should I check for an IP67 Waterproof installation ?

Verify the sealing configuration of both mated interfaces. At each Rosenberger branch, check that the mating plug, cable seal and sealing cap are specified for the installation.
