9 Pin 15 Pin 25 Pin VGA Cable Connectors Solder Type For Audio Video LED Displays

D-Sub and DVI are the current standard interfaces in PC environments.

Known officially as D-Sub miniature, D-Sub is not exclusive to display use. It's also used for serial-port, parallel-port, SCSI, and other connectors, with the number of connector pins depending on the purpose of use. However, these connector standards are rarely if ever found in PCs now for general-purpose personal use, most such applications having migrated to USB.

Manufacturing Technique

• Male+female generally refers to both ends of a complete set of connectors or extension lines, with pins on the male plug and holes on the female socket.
• DB9F 9 pin Serial DB9 Female to DB9 Female Connector. - 2 serial ports can transfer the data between 2 serial devices. For Cross wired canbe design which can ensures no conflict in data transmission and a reliable serial connection.
• Widely used in various connectors and connectors such as computers, instruments, machines, electrical appliances, LED displays,automobiles, color TVs, air conditioners, DVDs, VCDs, etc.

We can differentiate D-sub connectors using several factors:

• Number of pins or jacks. Letters A through E and their corresponding numbers indicate the number of contacts in the shell of each connector’s plug or socket. For example, the smallest common type of D-sub is the DE-9 (also DB-9), made up of a plug with nine pins matched to a socket with nine jacks. Some D-subs have “HD” added to their names, which indicates that they are high-density. HD D-subs feature a closer arrangement of pins and jacks within the shell.
• Connection Methods. D-sub connectors vary in how they connect the contacts and the system circuitry. One of D-subs’ advantages is that they are well-suited for locking technology. Locking technology means that hardware keeps the plug and socket components in the mated position – usually by way of screws inserted into threaded holes attached to the metal shell of each part. Locked D-sub ports are more resistant to tampering and jostling than USB ports, HDMI, or Thunderbolts.
• Connection Duration. D-sub ports also offer a range of connecting styles for other uses, such as crimping (easiest for temporary and at-home connections) and soldering (for more permanent connections).

Another subtype of D-sub connector is an ITT trademark called the microminiature-D or “micro-D.” Micro-D connectors are even smaller than standard D-subs, and you can find them in use almost exclusively for space-grade technology.
