The High-Density variant is the more advanced option, as it can be used in military, defense, and commercial aviation industries and withstand harsh temperatures. It features a robustly designed shell contact and is available in a straight plug, in-line receptacle, or rear panel mount receptacle for its connector types.

Several Standard variants also feature straight plugs, rear mount receptacles, and in-line receptacles. These are ideal for many applications with lower current ratings and contact configurations.
