| Mating End Types |
|
A plug is the connector in a mating pair which has the active mating mechanism (rotating coupling nut, spring lock, etc.). A jack is the connector in a mating pair which has the passive mating mechanism (bayonet studs, grooves for spring locks, external threads, etc.). Most RF connector series incorporate a male contact in the plug and a female contact in the jack. Some series are available in polarized versions (with the male contact in the jack and the female contact in the plug) so that plugs in close physical proximity to each other can only be mated with the correct jack. In polarized interfaces the insulators are reversed as well, if the series uses overlapping insulators. Some series (such as SMB and SMC) are designed with the female contact in the plug and the male contact in the jack as a standard configuration. Because of this, and the existence of polarized versions of other series, the term "male" and "female" should never be used to define a connector's gender; always specify "plug or "jack" in order to avoid confusion. Note: G874 connectors are hermaphroditic (any connector will mate with any other connector). See our size comparison chart to see the plug and jack configuration in each of our standard series.
