Material & Rating
- Housing — PA66 or PBT glass-filled, bayonet or Insta-Click positive lock coupling
- Contacts — brass or copper alloy, gold-plated, crimp type, 8 or 12 positions
- Seal — silicone peripheral and wire seals; coupling seal on the mated pair
- Coupling — bayonet (Insta-Click positive lock) for fast, vibration resistant mating
- Temperature — rated to the connector supplier specification; stated on the drawing
- Voltage and current — rated per supplier specification for the 8 pin and 12 pin versions
- Ingress protection — mated pairs sealed per drawing, typically IP67; verified on the sample
Certification
Cactus Electronics is certified to ISO 9001, IATF 16949 and UL and manufactures to the IPC/WHMA-A-620 workmanship standard. Raw materials comply with RoHS. Every assembly passes 100 % electrical testing - continuity, insulation resistance and withstand voltage - before packing, and the QC-to-production personnel ratio is 1:3.

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 and seal; cables assembled to these connectors are normally PVC at 80 °C or PUR for outdoor use. 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?
These connectors seal at the coupling and at each wire entry, so a mated pair is protected against water and dust - typically IP67 - and the level is confirmed on the sample. 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. Shell size, position count, plug or receptacle, coupling style and cable assembly are all customer-defined. 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.
