A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.
Revision A [2] changed these interchange circuits to Category II (para 4.3.6 and 4.3.7 of the standard [3]) and added a "Ring Indicator" on pin 22. Pin 23 is grounded in TIA-530-A. Confusion between the revisions has led to many incorrect wiring diagrams of this interface and most manufacturers still adhere to the original TIA-530 standard.
General Motors implemented both a 5-pin connector and a 12-pin connector, with the 12 pin connector (Packard/Delco/Delphi part number 12020043) being used in the vast majority of GM cars. Lotus implemented a 10-pin connector. The pins are given letter designations in the following layouts (as seen from the front of the vehicle connector): 12 ...
The part number of a pole piece and plate assembly can be dete3rmined by visual inspection by the colored ties or connectors ant he number of teeth on the timer core and pole piece. The following is a list of pole piece and plate assemblies by pick-up coil color code. Blue tie or black connector body: 1876210 (V-8), 1891209 (V-6), 1880020 (L-4)
The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles, trucks, and motorcycles used to interface a scan tool with the control modules of a given vehicle and access on-board diagnostics and live data streams. [1] Prior to 1996, many OBD-I data link connector's were in the engine compartment, usually near the ...
Male pinout of a 25-pin serial port (D-subminiature, DB-25) commonly found on 1980s computers. The following table lists commonly used RS-232 signals (called "circuits" in the specifications) and their pin assignments on the recommended DB-25 connectors [14] (see Serial port pinouts for other commonly used connectors not defined by the standard).
Because personal computers first used DB-25 connectors for their serial and parallel ports, when the PC serial port began to use 9-pin connectors, they were often labeled as DB-9 instead of DE-9 connectors, due to an ignorance of the fact that B represented a shell size. It is now common to see DE-9 connectors sold as DB-9 connectors.
