Board-to-Board, Wire-to-Board 2.54mm Pin Headers:

We offer a vast range of these simple and cost-effective connector types

A pin header is a form of electrical connector. A male pin header consists of one or more rows of metal pins moulded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. Male pin headers are cost-effective due to their simplicity. The female counterparts are sometimes known as female socket headers.

Normally pin headers are through-hole devices (THD / THT), but surface-mount devices (SMD / SMT) exist too. In the SMD case, the solder side of the pins are bent on a 90-degree angle for soldering to PCB pads.

Headers can be either straight (vertical) or right-angle, the latter form is sometimes used to connect two PCBs together horizontally.

Most often, headers are available in one or two rows, though three or more rows are available from some manufacturers.
