Clean housing and terminals with anhydrous ethanol to remove dust, oil or other conductive contaminants before installation.
Prevent oil contamination and water vapor ingress by ensuring proper sealing and IP rating compliance in harsh environments.
Use compliant insulating materials (PBT, PA66) with high dielectric strength to meet voltage resistance requirements.
Conduct periodic insulation and voltage resistance tests; replace non-compliant connectors immediately to avoid safety risks.
Technical Note: Testing should be performed in a temperature-controlled environment (23±5℃, 45-75% RH) to ensure accurate results. For connectors in outdoor applications, increase testing frequency to quarterly.
