Pin Header Connector

Pin header, a type of connector, English name: Pin Header.

This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to serve as a bridge between circuits that are blocked or isolated and not connected within the circuit, undertaking the task of current or signal transmission. It is usually used together with female headers to form board-to-board connections; or used together with electronic wire harness terminals to form board-to-wire connections; it can also be used independently for board-to-board connections.

Since different products require different specifications, pin headers also come in many models and specifications. According to the standard classification of pin header connectors in the electronics industry: by pitch, they can be roughly divided into eight categories: 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.5mm, 2.54mm, 3.96mm, and 5.08mm; by number of rows, there are single-row pin headers, double-row pin headers, triple-row pin headers, quadruple-row pin headers, etc.; by packaging usage, there are SMT (horizontal mount/vertical mount), DIP (straight insert/bent insert), etc.; by installation method: 180°, 90°, SMT indicated

Number of pins: 2P to 100P

Pin legs: straight legs, bent legs, SMT;

Pin material: brass or phosphor bronze;

Insulator material: plastic PA66, PA46, PBT, PA6T, PA9T, PPS, LCP, etc.

Surface treatment: gold plating (0.8u", 1u", 3u", 5u", etc.), tin plating, half-gold matte tin, half-gold bright tin.

Packaging: PE bag, roll bag, tube.

Processing technology: First process the pins with brass (or phosphor bronze) as required, and first nickel plate then gold plate as required, then process the insulator part with a mold, and finally insert the pins into the insulator on special equipment according to dimensional requirements.

Pin header applications: ●Data processing●Computers●Program control equipment●Electronic measuring equipment●Automatic control●Automation●Communications

Note: There are many factors affecting the price. Usually the most influential are gold plating thickness, pin length, number of PINs, etc.
