Each of the previously mentioned D-sub connector styles is available in a waterproof format. Standard-density, high-density, and mixed layout connectors can be offered with an IP67 rating both for front and rear panel mounting and with either a plastic or zinc die-cast frame. There are also cable options that include backshells or hoods that retain a waterproof seal when mated and unmated. Another option offered is a hood that creates an IP67 seal around standard non-waterproof products when mated.
