This section provides an overview for pin sockets as well as their applications and principles. Also, please take a look at the list of 8 pin socket manufacturers and their company rankings.

A pin socket is an electrical element, a female terminal that can be connected by inserting pins (bare terminals aligned at regular intervals).
Pin headers are used to connect PCBs together or for modular products on a printer board. The pin spacing (pitch) is 2.54 mm or 2.5 mm, and the pin socket into which they are inserted are also manufactured at this pitch.
Since the socket is pin-shaped and can be welded to the PCB, pin socket can be used to easily provide terminals on the PCB for connecting pin headers.
Pin sockets are selected according to the pitch and number of pins of the pin headers. Since the number of pins in a pin header varies from product to product, some pin sockets can be cut or folded at any point to use only the required number of pins. Pin headers are used to connect PCBs to each other, PCBs to various sensor boards and other modules, and microcontrollers to their corresponding modules.
By using the appropriate wire diameter and socket size, it is also possible to connect by inserting jumper wires.
Pin sockets provide continuity by inserting stripped jumper wires or pin headers into the socket, but the diameter and length of the wires must be compatible with the pin sockets. If the socket is too deep, the wire will not conduct even if it is inserted, and if the socket is too shallow, the wire will easily come loose, so care must be taken in the selection.
Pin sockets and pin headers can be used to easily connect and disconnect multiple contacts with a single insertion and removal, but there are a few things to keep in mind.
Pin sockets have no restrictions on the direction in which they can be inserted, so it is possible to connect pin headers in the opposite direction from that in which they were designed. Therefore, when using them, it is necessary to take measures to prevent the physical orientation from being changed, or to design circuits in such a way that changing the orientation does not have a significant impact.
In addition, when soldering pin sockets to connect modules with pin headers or IC modules on boards, working with pin headers inserted into pin sockets may cause the heat from the soldering iron to be conducted to the module, resulting in module failure. If you are familiar with soldering work, you may temporarily fix the module by soldering several places in the shortest possible time with the pin headers inserted.
