How mechanical latching supports sealed charging The charging security of sealed connectors can also be improved through mechanical latches. A latch handle features a pin that is released from the receptacle socket only when the handle is physically depressed. This prevents the connector from being accidentally dislodged during charging. By guaranteeing a tight, secure connection, a latching handle helps stop water and dust ingress, enhancing safety and reliability.
attaches the cap to the connector housing and keeps it nearby when the equipment is charging. A dust cap’s IP68 rating indicates complete protection against dust and moisture ingress. This ensures the connector surface remains clean and dry, preventing performance issues associated with exposing connector contacts to harsh environments.

A dust cap seals the end of a connector that is not in use (left), while an IP68-rated kit seals the two mated connectors being used to charge the equipment (right). How environmental protection extends lifespan For outdoor charging systems, sealing all three possible points of failure prepares connectors for environmental challenges at every stage of a connector’s day-to-day operation. Together, features like IP68-rated sealing kits, mechanical latching, and IP68-rated dust caps help ensure a connector is designed for durability. As the material handling, ground support, and construction industries increasingly adopt electric-powered equipment that needs to be recharged in outdoor environments, these next-generation sealed chargers help extend connector lifespan, enhance safety, and maintain electrical performance.
How to protect a connector while equipment is in service For complete outdoor protection, the remaining two connector failure points must also be addressed. Both the battery-side and equipment-side connector must remain sealed when they are unmated and the equipment is in service. Leaving either end openly exposed to air permits moisture and dust to enter, which can compromise electrical performance the next time the equipment is connected for charging. One solution involves placing IP68-rated dust-sealing caps over each connector. These caps deliver a precise, snug fit over the contacts and protect the connector while unmated. A dust cap is similar in function to a car’s gasoline cap, providing a sealed, clean cover for protection when not in use. To prevent the cap from being misplaced, a tether might be included that
