DA-26 male connector, sometimes incorrectly called DB-26HD or HD-26 The DB13W3 connector with three coaxial connections and ten ordinary pins Male DB13W3 connector (plug). Later D-sub connectors added extra pins to the original shell sizes, and their names follow the same pattern.
A MIL-DTL-38999 circular connector plated with a nickel–teflon composite. Left: plug (male) type connector; Right: receptacle (female) type connector) Electrical or fiber-optic connectors used by U.S. Department of Defense were originally developed in the 1930s for severe aeronautical and tactical service applications, and the Type "AN" series set the standard for modern military circular ...
Another disadvantage to MIL-DTL-5015 connectors is that they have only one keyway, [13] unlike some later connector specifications, such as MIL-DTL-38999. This limits the connectors' ability to be polarized to prevent mis-mating of same-shell-size connectors in an area where multiple sets of plugs and receptacles exist.
The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.
Twin BNC (also known as twinax) connectors use the same bayonet latching shell as an ordinary BNC connector but contain two independent contact points (one male and one female), allowing the connection of a 78 ohm or 95 ohm shielded differential pair such as RG-108A. [17] They can operate up to 100 MHz and 100 volts.
Both terms mean the same thing but could be construed to be completely different items. Similarly, a male standard-density D-sub with a size 1 shell can be named DE9M or DE9P; a female standard-density D-sub with a size 2 shell can be named DA15F or DA15S; a male high-density D-sub with a size 3 shell can be named DB44M or DB44P; and so forth.
The connector reliably carries signals at frequencies up to 100 MHz. [1] The coupling shell has a 5 / 8 inch 24 tpi UNEF standard thread. [4] The most popular cable plug and corresponding chassis-mount socket carry the old Signal Corps labels PL-259 (plug #259) and SO-239 (socket #239). [12]
