Custom Communication Cable Assemblies

Please provide the equipment application, communication or signal type, connector models or mating interfaces, pin assignment, cable length, electrical requirements, shielding and grounding requirements, and operating environment.
If available, you can also send drawings, connector part numbers, cable specifications, photos or an existing sample for evaluation.

Connector and cable selection should start with the required signal or communication interface, number of contacts, electrical requirements, cable construction and equipment installation conditions.
For a custom project, INTE-AUTO can review these requirements and recommend suitable push-pull, circular, coaxial or other connector and cable configurations.

Twisted pairs are commonly considered for differential signals and other circuits where the relationship between paired conductors is important.
The required pair construction, conductor size, shielding and cable specification should be selected according to the actual signal interface and system requirements.

Coaxial cable can be used for RF, video and other signal applications requiring a defined characteristic impedance and shielded transmission path.
The coaxial cable, connector and impedance should be matched to the equipment interface and transmission requirements.

The impedance should match the equipment interface and the communication or signal system. It should not be selected based only on the connector appearance.
50Ω is commonly used in many RF and communication systems, while 75Ω is commonly found in video and certain signal transmission applications. The complete connector and cable configuration should be confirmed before production.

Shielding and grounding should be defined according to the signal type, cable construction, equipment grounding architecture and EMI environment.
Depending on the application, individual shielding, overall shielding, foil, braid or combined shielding may be considered. Shield termination and connector-shell grounding should be clearly defined in the cable assembly drawing.

Yes. Cable length can affect signal attenuation and other transmission characteristics, especially for higher-frequency or higher-data-rate applications.
The acceptable cable length depends on the signal or protocol, cable construction, connector interface and system requirements. For applications with specific transmission-performance requirements, the complete cable assembly should be evaluated and tested accordingly.

Yes, when permitted by the equipment design and connector configuration.
Different conductor sizes, twisted pairs, coaxial contacts and shielding structures can be considered according to the required power, signal and data circuits. Circuit arrangement, shielding and grounding should be reviewed before the final design is approved.

The pin assignment should be based on the mating equipment interface and the required power, signal, data and grounding circuits.
For twisted pairs, coaxial circuits, shields and grounding points, their relationship should be clearly identified on the drawing. INTE-AUTO can manufacture according to a customer-supplied pinout or prepare a cable assembly drawing for approval.

Yes. We can evaluate an existing drawing, connector part number, cable specification or physical sample as a reference for developing a replacement or customized cable assembly.
The connector interfaces, pin assignment, cable construction, shielding, grounding, finished length and other assembly details are reviewed before a new drawing and prototype are prepared.

Connector orientation can be defined using the keyway, alignment mark or another fixed reference point. For right-angle or overmolded connectors, the cable exit direction should also be clearly shown on the drawing.
Finished cable length should be defined using agreed measurement reference points to avoid dimensional differences during production and inspection.

Before mass production, the connector models, pin assignment, wiring, cable specification, finished length, shielding, grounding, connector orientation, BOM and test requirements should be confirmed.
Depending on the project, testing can include continuity, pin-to-pin verification, insulation resistance, withstand voltage and specified functional testing. If specific communication or transmission performance is required, the acceptance criteria and test method should also be defined before production release.
