The HD Audio 3.5 mm subminiature audio jack differed from connectors used in the AC'97 specification and in general audio equipment. The AC'97 used a regular 3.5 mm audio jack, which typically has 5 pins: one pin for ground, two pins for stereo signal, and two pins for the return signal.
Perhaps the most comprehensively known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.
Unlike the original Eurocard solutions such as VME, which use connectors with a 0.1 inch (2.54 mm) pin spacing, CompactPCI cards use metric connectors with a 2-millimeter pin spacing, designed to the IEC 1076 standard. 3U boards have a 110-pin connector (J1), which carries the 32-bit PCI bus signals, and an optional 110-pin connector (J2 ...
AC'97 and its 2004 successor Intel High Definition Audio have been widely adopted specifications that, while not mandating physical sockets, do provide specifications for a front panel connector with pin assignments for two ports with jack detection. Front panels commonly have a stereo output socket for headphones and (slightly less commonly) a ...
The MIL-STD-704 power connections provide the store with access to 28 VDC, three-phase wye 400 Hz 115/200 VAC, and 270 VDC aircraft power; it is usual to route only one of the last two supplies, however, if both are made available, then they are never made active simultaneously.
REDEL 6-pin connector by LEMO, known as "LEMO plugs". [10] [1] Most Cirrus aircraft use this connector. [9] Fischer 8-pin connector, used in Agusta helicopters [5] Neutrik neutriCON 8-pin connector [11] [12] [13] The XLR, LEMO and Fischer plugs are able to supply power for active noise cancellation.

Pin-to-pin compatible devices share an assignment of functions to pins, but may have differing electrical characteristics (supply voltages, or oscillator frequencies) or thermal characteristics (TDPs, reflow curves, or temperature tolerances). As a result, their use in a system may require that portions of the system, such as its power delivery ...
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.
