These pin and sleeve connectors have watertight constructions that protect their internal components from liquids, debris, and dust. They provide safe electrical connections when mated with compatible watertight devices in outdoor and wet like food processing plants, beverage manufacturing, agriculture machinery, and chemical processing plants.

These pin-and-sleeve connectors provide electrical connections in hazardous environments where the possibility of flammable gases, vapors, or liquids, ignitable fibers or flyings, or combustible dust may exist under normal and abnormal conditions. They have location ratings that classify their suitable environment for operation and must be mated with compatible hazardous-location devices to be compliant.
