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 blocked or isolated circuits in 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, four-row pin headers, etc.; by packaging usage, there are SMT (horizontal/vertical), DIP (straight/bent), 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, reel 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 size requirements.

Pin header applications: ●Data processing●Computers●Program control equipment●Electronic measurement 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.
