Connector and backshell environmental protection ratings

The way that the degree of protection from fluids etc is defined, will vary depending on the style of connector or backshell as follows:
1) Military Qualified (QPL) connector environmental protection ratings:
These are defined in the relevant military specifications document & often only refer to the front end protection when mated. With certain series for which rear accessories are sold separately, rear end protection rating can not be defined within the connector specification. There are a variety of choices available for the rear end of these connectors, with varying degrees of protection.
2) Military Qualified (QPL) backshell environmental ratings:
These are defined in the relevant military specifications document.
3) Commercial (Military compatible) backshell environmental protection ratings:
Companies like Glenair make many commercial backshells that are compatible with the military qualified (QPL) connectors. Usually the manufacturers of these items do not use the European IP rating system in their product specification. Instead they offer their own definitions. For example, with Glenair Series 39 - EMI/RFI Cable Sealing Backshells, they offer 3 sealing options described as follows: "Cable sealing options include full-immersion to 6 ft., water-tight to 3 ft. and splash-proof".
4) European ingress protection ratings (IP ratings):
These ratings are often used for commercial, non-Military style connectors. (Military qualified "QPL" connector ratings are defined differently as described above). Please refer to the following chart for IP ratings information.
