2.54mm dual-row SMT female header with guide posts (screw-lockable) / professional customization / LED light connector /

Female header, a type of connector.

1. Application: This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments.

2. Function: Its function is to serve as a bridge between blocked or isolated circuits in a circuit, undertaking the task of current or signal transmission. It is usually used together with a female header to form a board-to-board connection; or used together with the end of an electronic wire harness to form a board-to-wire connection; it can also be used independently for board-to-board connection.

3. Classification: According to pitch, it can be roughly divided into seven types: 0.8mm, 1.0mm, 1.27mm, 2.00mm, 2.54mm, 3.96mm, and 5.08mm (other special pitches can also be customized as needed); according to the number of rows, there are single-row female headers, double-row female headers, triple-row female headers, quadruple-row female headers, etc.; according to packaging usage, there are SMT surface mount, DIP through-hole (straight/right-angle), etc.; according to installation method: 180 degrees, 90 degrees, SMT; according to whether height increase is needed and whether positioning posts are needed, there are 2 types of positioning posts, one is an inner positioning post, and the other is an ear positioning post; Female header terminal types: U terminals and Y terminals (U-shaped terminals, with contact on 3 sides, are generally used for low plastic height; Y-shaped terminals, with contact on 2 sides, are generally used for high plastic height).
