What Is IP67/IP68 Waterproof Cable Assembly?

IP67/IP68 waterproof cable assembly is a custom cable assembly engineered for reliable electrical connections in wet, dusty, or submerged conditions. It features sealed connectors and overmolding to prevent water ingress, dust, and corrosion, meeting IP67 (dust-tight, 1m immersion for 30 minutes) or IP68 (deeper, longer submersion) standards.

Compared with standard cable assemblies, a custom waterproof cable assembly is designed for the exact equipment layout, installation space, electrical load and working environment. It helps improve assembly efficiency, reduce field wiring errors, protect signal and power transmission, and extend product service life in outdoor or harsh operating conditions.

Frequently Asked Questions

What is the difference between IP67 and IP68 waterproof cable assemblies?

IP67 assemblies are dust-tight and withstand 1m immersion for 30 minutes, ideal for rain or splashes. IP68 goes further, handling continuous deeper submersion (e.g., 3m+ per specs), suiting underwater or high-pressure uses. Yihetai customizes both with overmolding or potting, tested to exceed standards, ensuring reliability in marine, industrial, or automotive apps. We match exact ratings to your environment for optimal performance and cost.

Can you produce custom IP67/IP68 cable assemblies based on my drawing?

Yes, as a custom cable assembly supplier, we manufacture from drawings, samples, or specs. Our team reviews for feasibility, suggests improvements like better sealing or shielding, and prototypes in 5-7 days. We’ve handled thousands of OEM wire harness projects, covering wire types, lengths, and connectors like M12 or Deutsch.

What industries do your IP67/IP68 waterproof cable assemblies serve?

Primarily harsh-environment sectors: industrial automation, marine, automotive, renewables, and defense. Examples include sensors in wet factories, EV underwater connectors, or solar farm wiring. Our custom wiring solutions adapt to specifics, with materials resisting UV, chemicals, and vibration for long life.

What testing do you perform on waterproof cable assemblies?

Every unit undergoes 100% electrical testing: continuity, insulation resistance, high-pot (up to 5kV), crimp pull-force, and IP-rated immersion. Additional salt spray, thermal cycling, and vibration per customer needs. This guarantees field reliability, backed by ISO/IATF certifications.

What is your minimum order quantity for custom IP67/IP68 assemblies?

Prototypes start at 1-10 pieces for testing; Production MOQ is 100-500 based on complexity. Flexible for startups or high-volume OEMs. Fast quotes within 24 hours, with volume discounts as your wire harness manufacturer partner.
