A pin header is typically a simple and inexpensive type of electrical connector used for the connection of computer hardware and other electronic assemblies. A standard male pin header comes with one or more flat rows of small metal contacts molded into a thin plastic backing, usually 2.5 mm in thickness. A plastic sleeve is then soldered around the edges of the contacts. The plastic sleeve fits inside a hole drilled in the breadboard or other surface and has an eyelet on one or both sides to allow access to the pins.
Male pin headers can be purchased from standard computer supply stores at very low prices. Most commonly these are used for connection of serial ATA boards. The standard ATA board identification pin number is 0xE0, followed by two digits, for example, EE: EO. The most common uses are for connections between serial ports and external devices. A double row pin header may also be used to attach two parallel pin connectors, to support two independent data signals.
There are several types of pin header available, depending on what it is being used for. The most inexpensive and easiest type is the single-row pin header, which has a female attachment and male attachment that easily mate with each other. This type provides the best connection speed and is suitable for low-cost applications. It is also easy to install.
A more expensive, though less reliable option is the shrouded header, which contains two rows of sockets - one in the front (female) and one in the back (male). The female attachment is held in place using a female clip, which can be easily removed when needed. One advantage of using a shrouded header is that there is no need for an extra mating device.
There are also two different types of pin header connectors, each having different advantages. The two types are generally classified as hot-swappable and opt-in. Hot-swappable connectors are very popular because they enable one to transfer power and information quickly, even when the power or signal is interrupted. This is particularly useful for high-volume applications, where the time difference between two separate connections could be critical.
Another type is the opt-in header connector, which can provide security for data and power transfers. These have terminals protected by a plastic shield, typically made of plastic laminated around aluminum or stainless steel. This shield prevents the user from seeing the data feed and protects against undesired hits or unwanted power surges. These pins are equipped with wiring interfaces that allow you to attach two or more pcb connectors to the same PC board. The wiring interfaces can be kept secret, so that only the authorized personnel know about the number of connections. However, if these wires are exposed then this would cause security issues for those users who have unauthorized access to these PC boards.
Most often, manufacturers will standardize on the PC board design and then select a compatible cable or connector. In order to meet the needs of different applications, the cable should have the correct pin size and cable routing for the application, so that it can support a specific function. The best way to ensure that the PC board connectors meet the requirements is to look at the plating options available for the connector. For instance, a thin gold or copper shield will provide excellent protection, especially for a high-volume application like a computer motherboard. You can find many plating options available in the market today and most of them are able to meet the needs of different connectors.
Other features worth considering include extreme thermal resistance, excellent conductor melt performance and shrinkable cable lengths. However, it is essential to choose the correct PCbs for the job and select only those with the right sleeve length, sleeve thickness, sleeve style and IDC.
