The various classes and types of connectors are intended for application as follows (see 1.3.2):
a. Classes E, J, and P (series 1) solder connectors are intended for use in environment-resisting applications where the operating temperature range of -55 to 125 °C is experienced. Crimp contact connectors have the additional advantage of possessing removable crimp-type contacts and a higher temperature rating (175 °C). Class J connectors are intended for use with lightweight single-jacketed cable.
b. Classes N and H connectors are intended for use in applications wherein pressures must be contained by the connectors across the walls or panels they are mounted on. Class N connectors have the additional advantage of possessing removable crimp-type contacts. Class N connectors are rated at a high temperature of 200 °C while class H connectors are rated at 125 °C maximum for series 1, 200 °C maximum for series 3.
c. Class L and E, series 3, connectors are intended for use in environment-resisting applications where the operating temperatures are in a range of -55 to 175 °C for class L, and -55 to 200 °C for class E.
d. Cylindrical miniature spherically oriented rack and panel plugs are intended for use in environment-resisting applications where blind mating conditions occur. Rack and panel plugs will accommodate up to 0.050 inch of initial misalignment in any direction between mating connectors
e. Crimp contact connectors (except class N) 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 sealing connectors.
f. The potting form should remain with the connector after potting.
g. Counterpart solder and crimp contact connectors are intended to be intermateable, but performance is then reduced to that of the solder contact connector.
h. If air leakage requirements are critical, a hermetic receptacle should be used.
i. AS31301 series solder-type connectors do not have an interfacial seal. Therefore, these connectors should not be used where such a seal is required.
j. For finished wire diameters less than specified in Table 4, shrink-fit sleeving should be used over the wire.
k. Where two or more wires are used in a solder cup or wire barrel, moisture sealing is not obtainable. Wires should be potted if sealing is required.
l. Class N hermetic crimp type series do not have grommet seals. Connectors should be potted if wire sealing is required.
m. 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. It will be the user's responsibility to prevent the inadvertent cross mating of a shielded contact with a size 12 power contact.
