Compatible accessories and bundles

Ordering the connector alone is often only part of the job. Consider accessory bundles we commonly recommend for rapid assembly:

• Contacts and crimp tooling matched to contact size.
• Cable clamps and backshells for strain relief and EMC control.
• PCB headers and shrouds to match mating housings.

We group compatible items on product pages so you can easily add the correct contacts and tools when you Shop Now from the category pages.

Selection guidance, compatibility and quick checks

Use this quick checklist before you place an order: confirm mating gender, pin numbering, panel cut-out or PCB footprint, and the conductor cross-section for crimp contacts. When in doubt, request a parts list or sample pack to validate fit on the bench.

Wiring diagram examples

For simple cable-to-board harnesses, a common arrangement is shown below (pin numbers left-to-right when viewed from mating face):

Label both ends and use heatshrink or colour-coded sleeves for reliable harness builds in student labs or small production runs.

Troubleshooting common issues

• Loose mating: check for bent pins or incorrect shell style and replace worn contacts.
• Overheating at high current: confirm contact size and cable gauge; upgrade to higher current-rated pins where needed.
• Mismatched PCB footprint: verify footprint against the supplier drawing and request a PDF/datasheet when needed.

Our technical team can help interpret datasheets and confirm compatibility. Learn more about our company and support ethos on the About page: About Communica.
