Waterproof Harness FAQ
The required IP rating depends on your environment: IP65 for water spray, IP67 for temporary immersion, IP68 for continuous submersion, and IP69K for high-pressure wash-down. We can help you select the appropriate rating based on your specific conditions and requirements.
We use multiple sealing methods depending on the application: O-ring seals, gaskets, potting/encapsulation, heat shrink with adhesive lining, and overmolded connections. The sealing method is selected based on IP rating requirements, connector type, and environmental conditions.
We can create sealed assemblies using connectors from most major manufacturers that offer IP-rated options, including TE Connectivity, Molex, Amphenol, and others. We can also overmold or pot standard connectors to achieve sealing when sealed versions aren't available.
We test waterproof assemblies per IP rating standards. This includes dust chamber testing for the first digit and water immersion or spray testing for the second digit. We can provide test reports and certificates of compliance with your required IP rating.
