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 i n environment- resisting applications where the operating temperature range of -550 to 125°C 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 where in 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 be untreatable. Moisture resistance capability is then reduced to that of the solder contact connector.

(f) If air leakage requirements are critical, are silent 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 slaving 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.
