Pin headers are a form of electronic connector that is widely used in electronic or instrumentation of the PCB function, acting as bridge between two pcb’s which are blocked and used to take the current or signal transmission. It consists of one or more rows of male pins typically spaced 2.54mm apart, however common sizes also include: 5.08mm, 3.96mm, 2.00mm, 1.27mm and 1.0mm. The distance between pins is commonly referred to as the pitch in the electronic community. The pin header is made of plastic and metal contacts and is usually inserted into the female header for connecting the board to another board.
Pin Header, a type of connector.
This connector is widely used in electronic, electrical, instrument in the PCB circuit board, its role is in the circuit is blocked or isolated between the circuit, play a bridge function, take up the task of current or signal transmission.It is usually used with the busbar to form a board-to-board connection.Or matching with the electronic wiring harness terminal, forming a board-to-wire connection;Can also be used independently for board to board connection.
Because the specifications required by different products are not the same, there are also a variety of pin specifications, according to the standard classification of pin connectors in the electronics industry:
According to the spacing can be roughly divided into 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm five categories according to the number of rows have a single row of needles, double row of needles, three rows of needles;According to the packaging rules with SMT(horizontal paste/vertical paste), plug-in DIP(direct insert/bend insert);According to the installation mode, 180° is represented by S, 90° by W, and SMT by T.
Number of rows: single row, double row, three row, four row at most.
Pin number: 02 to80
Stitching: straight foot, bent foot, SMT;The size of the needle.
