The connectors are manufactured in many capacities, including 14-, 24-, 36-, 50-, 64-, and 100-pin varieties. They may be mounted on boards, panels, or may terminate cables. Wires are attached by means of solder, crimping or insulation displacement. Female connectors have bail locks for a sturdy connection to the male connector. Screws may also ...
Later Macintosh models use 8-pin miniature DIN connectors instead. On PCs, 25-pin and (beginning with the IBM PC/AT) 9-pin plugs were used for the RS-232 serial ports; 25-pin sockets were used for parallel ports (instead of the Centronics port found on the printer itself, which was inconveniently large for direct placement on the expansion cards).
A more recent design variation which allows for higher density connections is the dual row micro lead frame (DRMLF) package. This is an MLF package with two rows of lands for devices requiring up to 164 I/O. Typical applications include hard disk drives, USB controllers, and wireless LAN.
Sun Microsystems and Data General used a 50-pin 3-row DD-50 connector, which was sometimes incorrectly called a "DB-50" or "HDB-50". Sun also used DB-25s on a few products. Digital Equipment Corporation mostly used the CN-50, but the VAXstation 3100 and DECstation 3100/2100 made use of a MALE 68-pin connector on the rear of the workstation ...
PS/2 female socket pin numbering: note that it is a mirror of the male connector. The mini-DIN connectors are a family of multi-pin electrical connectors used in a variety of applications. Mini-DIN 9.5 millimetres ( 3 ⁄ 8 in) is similar to the larger, older 13.2 mm diameter DIN connector .
Shrink plastic dual in-line package (SPDIP) – A denser version of the PDIP with a 0.07 in (1.778 mm) lead pitch. Skinny dual in-line package (SDIP or SPDIP [ 6 ] ) – Sometimes used to refer to a "narrow" 0.300 in. (or 300 mil ) wide DIP, normally when clarification is needed e.g. for DIP with 24 pins or more, which usually come in "wide" 0. ...
The quad flat-pack has connections only around the periphery of the package. To increase the number of pins, the spacing was decreased from 50 mil (as found on small outline packages) to 20 and later 12 (1.27 mm, 0.51 mm and 0.30 mm respectively).
A low-force helix (LFH-60) is a 60-pin electrical connector (four rows of 15 pins) with signals for two digital and analog connectors. Each of the pins is twisted approximately 45 degrees between the tip and the plastic frame which holds the pins in place. Hence "helix" in the name. The DMS-59 is a derivative of the LFH60.
