Inside the Hirose GT32 B Key to B Key Assembly
Two Green B Key Ends for the Same Mating Profile
Both ends use the original green Hirose GT32-4DS-HU(B) shell and the Hirose GT32-4DS-1.5C connector. The green shells make the cable easy to identify on a bench that also handles other GT32 variants. For purchasing and sample approval, the full shell number identifies the mechanical key more precisely than color alone. Check the mating part number at each module, especially when the two ports are mounted in different orientations. Each latch needs enough clearance for the operator to seat and release its connector after nearby brackets or covers are in place. www.hirose.com
Straight Through Wiring for Module Integration
Blue, orange, green and brown conductors connect pins 1 through 4 to the same numbered pins at the opposite end. The drawing also shows a separate connection between the metal shells. This arrangement gives technicians a clear sequence for checking contact continuity and the shell path independently. During design review, compare the signal assigned to each pin on both modules. The two ports can share the same mechanical key while using different electrical assignments, so the module pin tables are the reference for determining whether the straight through wiring fits the application.
DACAR 535 With a Defined Electrical Specification
The drawing identifies DACAR 535 as the cable and specifies 100 Ω nominal impedance, a frequency range from DC to 2 GHz and a dielectric withstand voltage of at least 500 V RMS. These values give engineering and sourcing teams a common reference when reviewing the sample or evaluating a proposed material change. Keep the cable designation and electrical requirements together in the purchase specification. For system validation, evaluate the cable with the intended mating connectors and module interfaces, since the application protocol and data rate depend on the complete link.
A Controlled Two Meter Span for Routed Installations
The 2,000 ± 20mm dimension applies between the reference points near the connector exits. The drawing lists a separate 28.4mm nominal reference dimension at each end and calls out black sleeving at both cable exits. When checking fit, measure along the path the cable will follow around brackets, guides and enclosure walls. Allow room for the connector bodies and access to both latches. On a fixture with removable modules, check that each unit can be moved far enough to release the connector without pulling on the cable.
Where the USB Female End Fits
| Application | How PCM-ZC-0242 is used |
|---|---|
| Automotive infotainment integration | Link a head unit and a remote module when both use mating Hirose GT32 B Key ports with compatible signal assignments. |
| Vehicle harness layout trials | Route a sample between the intended module locations to check cable reach, clip positions and access to the release latches. |
| Module integration benches | Connect modules mounted apart on a test rig and use the documented wiring to verify continuity before system testing. |

Product FAQ
Which Hirose GT32 key is used at each end ?
Both ends use the green Hirose GT32 B Key shell, part number GT32-4DS-HU(B).
Is the cable wired straight through ?
Yes. Each pin connects to the same numbered pin at the opposite end, and the metal shells are connected. Check that both modules assign the intended signals to those positions.
Does the 2 GHz specification indicate a data rate ?
The drawing lists DC to 2 GHz as the frequency range. Confirm the protocol and data rate against the requirements of the complete link.
What should I send PCM for a quotation ?
Send the mating Hirose part number at each module, your target cable length and measurement points, the required pin assignment and the estimated order quantity.
How is the 2m cable length measured ?
The drawing specifies 2,000 ± 20mm between the marked reference points near the cable exits. Use the separate connector dimensions when checking overall installation space.
