What are the wide range of applications for rows of pins?

Pin headers are widely used in the connection of PCB boards and are known as universal connectors. Generally used in pairs with its mother, wire ends and other connectors. With the pin connector market competition, now some manufacturers from the plating (imitation gold) and material (green steel, alloy, etc.) to start reducing costs, but also reduces the use of product characteristics and life. Pin header, a connector, English name: Pin Header, this connector is widely used in electronics, electrical appliances, instrumentation in the PCB circuit board, its role is to be blocked in the circuit or isolated between the circuit, play the function of the bridge, take up the task of current or signal transmission. Usually used in conjunction with the mother of the row, constituting a board-to-board connection; or used in conjunction with the electronic harness terminals, constituting a board-to-line connection; can also be used independently for board-to-board connection. Due to the specifications required for different products are not the same, so the row of pins also has a variety of models and specifications, according to the electronics industry's standard classification of the row of pin connector:

What are the wide range of applications of Pin Header? According to the pitch can be roughly divided into 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm five categories according to the number of rows of single row of pins, double rows of pins, three rows of pins, etc.; according to the encapsulation method of SMD SMT (lying paste / stick), plug-in DIP (straight / curved insertion), etc.; according to the mounting method of division: 180 ° with the S said that the 90 ° said that the W said that the SMT said that the T said. The number of rows: single-row, double-row, double-row, and so on. Number of rows: single row, double row, three rows, four rows, up to four rows. Number of pins: 02to80 Pin: straight, curved, SMT; pin size. Size: external dimensions length, width, thickness, row spacing. Pitch: 0.8, 1.0, 1.27, 2.0, 2.54 pitch. Material: the material and surface treatment of contact parts, insulator material. Packing: blister pack, roll bag, bulk pack. Material: pin material: brass or phosphor bronze; insulator material: plastic UL94V-0. Surface treatment: gold-plated 0.8u, tin-plated, nickel-plated. Processing technology: row of pins processing process is mainly: first according to the requirements of brass (or phosphor bronze) processed pins, and according to the requirements of the first nickel-plated and then gold-plated, and then the use of molds to process a good part of the insulator, and finally in the special equipment according to the size requirements will be set to the insulator pins. Note: There are many factors affecting the price, usually the greater influence is the gold plating, pin length, etc.. Examples of Pin Parameters Characteristics: Single and double rows, straight and curved pins, pin spacing of 2.54mm and 3.96mm, various pin lengths. Applications ● Data processing ● Computers ● Program control devices ● Electronic measuring devices ● Automatic control ● Automation ● Communication Rectangular pins with a cross-section of 0.8 x 1.6 mm and a load current of 7.5 A. The jacks have at least two independent shrapnel and four contact points, and the jack structure prevents accidental insertion. 254/I series square pins with a cross-section of 0.64 x 0.64 mm. The above two types of pins are designed with obtuse corners and can be used in high-frequency technology. The above two types of pins are designed with obtuse corners and can be used in high-frequency technology. The contacts are gold-plated for corrosion resistance, low contact resistance and high reliability.
