Many electrical connectors are designed to resist water ingress from rain, spray and humidity. But there are underwater applications that require waterproof electrical connectors or watertight electrical connectors. There is a distinct difference between being waterproof and water-resistant. Waterproof means the connector component is impervious to water regardless of how long it is submerged. Underwater ratings guide design engineers and purchasing agents to the appropriate connectors.
Connector waterproof ratings are typically defined using the Ingress Protection (IP) code system. This system rates how well a connector can withstand dust and water ingress. Typical ratings for immersible electrical components range from IP65 to IP69K. A complimentary NEMA rating, such as NEMA 250 (6P), which also defines ingress protection from solids and liquids, may also be noted in the connector specs.
Connector Impact:
Electrical connectors are exposed to any number of harsh environmental and operational stresses where watertight connections are a requirement. Applications include underwater lighting systems, fluid pumps, extravagant fountain shows, weather monitoring field stations, robotics, subsea oil and gas operations, marine research, renewable energy systems, and more. Saltwater, temperature, sun exposure, vibration and pressure can impact connectors’ ability to remain waterproof and provide reliable, uninterrupted performance.
