The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

In 20/24-pin configurations, the Mini-Fit Jr. connector (Molex Mini-fit Jr. 39-28-1203, [7] former 5566-20A or 39-28-1243, [8] former 5566-24A) may be used on ATX motherboards as the main power connector. The same style of connector, in single or paired 4-, 6-, or 8-pin configurations, may be used for additional CPU power and graphics card ...
Some commercial airlines require the use of TSO-compliant headsets, as part of their operations manual. [15] This is a choice by the airline, not an FAA requirement. [16] In Europe, the European Union Aviation Safety Agency (EASA) also issues TSOs. The TSO for aviation headsets is ETSO-C139.
All NEMA 6 devices are three-wire grounding devices (hot-hot-ground) used for 208 and 240 V circuits and rated for 250 V maximum, with the 6-15, 6-20 and 6-30 being grounding versions of the 2-15, 2-20 and 2-30, respectively. The 6-15 resembles the 5-15, but with collinear horizontal pins, spaced 23 ⁄ 32 in (18.3 mm) center-to-center. The 20 ...
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1] Male pin headers are cost-effective due to their simplicity.
For example, in Switchcraft XLR microphone or hydrophone connectors, the part numbers are denoted as follows: A3F = Audio 3-pin female connector; A3M = Audio 3-pin male connector. The terms plug, pin, and prong are also often used for "male" connectors, and receptacle, socket, and slot are used for "female" connectors.
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 ...
The 75 ohm connector is dimensionally slightly different from the 50 ohm variant, but the two nevertheless can be made to mate. Note that a male 50 ohm BNC has the pin larger than the one of a 75 ohm male, then it can widen the female, causing a fault connection when inserted later a 75 ohm male connector.
