The various classes and types of connectors are intended for application as follows:

a. Classes E, F, J, and P connectors are intended for use in environment-resisting applications where the operating temperature range of -55º to 125ºC (-67º to 257ºF) is experienced. Crimp contact connectors have the additional advantage of possessing removable crimp-type contacts. Class J connectors are intended for use with light-weight, single-jacketed cable.

b. Class H receptacles are intended for use in applications wherein pressures must be contained by the connectors across the walls or panels on which they are mounted.

c. Crimp contact connectors should have contacts installed in all positions when the connector is wired. Sealing plugs should be installed in the grommet holes when no wire is attached to the contact in grommet sealed connectors.

d. The potting form should remain with the connector after potting.

e. Counterpart solder and crimp contact connectors are intended to the intermateable. Moisture resistance capability is then reduced to that of the solder contact connector.

f. If air leakage requirements are critical, a resilient insert, solder contact receptacle, a through bulkhead receptacle, or class H receptacle should be used, or the connector should be potted.

g. For finished wire diameters less than specified in table II, shrink-fit sleeving should be used over the wire.

h. Where two or more wires are used in a solder cup or wire barrel, grommet sealing is not obtainable. Wires should be potted if sealing is required.

i. Connectors are available with finishes D, T, W and K for corrosion protection.

a. Connector backshells must be installed to meet the specified moisture sealing requirements.

b. Class A connectors are intended for use in application where 200ºC temperature, grommet seal, and nonconductive finish are required.

c. Class L connectors are intended for use in environment resisting applications at 200ºC temperature and are fluid resistant. These connectors have wire sealing grommets.

d. Class H and N receptacles are intended for use in applications wherein pressure must be contained by the connectors across walls or panels on which they are mounted. They have fluid resistant insert face seals. In addition, class N receptacles have crimp type terminations.

e. Mechanical strain reliefs are intended for use where a saddle type clamp is desired.

f. Shielded contacts are intended for use with shielded and jacketed single conductor cables, and may be used with certain coaxial cables when impedance matching is not required. Shielded contacts are not furnished with connectors, and must be ordered separately when required. Shielded contacts will not intermate with standard size 12 contacts or with series 1 shielded contacts. It is the user's responsibility to assure mating contact compatibility at time of contact installation.

g. RFI backshell and grounding fingers on plug are available in class L and provide RFI shielding.

h. Classes D, T, W and K connectors are intended for use in salt spray environments providing a corrosive resistant shell, conductive finish, and fluid resistance at 175°C (347ºF) service temperature.
