FAQ
What is the operating temperature rating of this harness?
Standard PVC-insulated assemblies are rated to 80 °C; XLPE or TPE insulation raises the rating to 105 °C. Temperature rating follows the supplier specification for the housing resin; harnesses built with these housings are normally PVC at 80 °C or XLPE at 105 °C. The exact operating range for a part number is stated on its drawing and confirmed in the sample test report.
Is this overmolded harness waterproof?
The Deutsch DT versions are the sealed members of this range - with wire and peripheral seals fitted, a mated pair is protected against water and dust. The Molex 3.0 series is an unsealed board-level housing. The ingress protection level (typically IP67 for a mated pair) is specified on the drawing and verified during sample validation. Non-overmolded assemblies can be supplied with heat-shrink or grommet sealing instead.
Can I customize the pinout and connector type?
Yes. Pinout, connector series and gender, cable length, wire gauge, jacket colour and overmold shape are all customer-defined. Position count, keying, header orientation and whether parts are supplied loose or terminated are all defined by your board design. Send a drawing, a sample, or a pinout table and we return a 2D/3D drawing prepared to IPC/WHMA-A-620 for approval before tooling.
What is your MOQ for custom cable?
MOQ is confirmed per project and depends on harness complexity, connector cost and tooling. Prototype and pilot batches are accepted before mass production, so a new programme can start with sample quantities. Samples are produced in 3–7 working days and mass production runs 20–30 days after approval.
What testing standards do you apply for harness?
Production follows IPC/WHMA-A-620. Every assembly is 100 % electrically tested for continuity, insulation resistance and withstand voltage; the in-house lab adds temperature and humidity cycling, salt spray, connector insertion and withdrawal force, and cable bending tests. Inspection records are kept in the ERP system.
