PIN HEADER 1.27mm DOUBLE ROW RIGHT ANGLE SMT TYPE H=1.0mm
Pin Header, a kind of connector
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, to play the function of a bridge, the task of current or signal transmission. Usually used in conjunction with the Female Header to form a board-to-board connection; or with the electronic harness terminal to form a board-to-wire connection; can also be used independently for board-to-board connection.
As different products do not require the same specifications, so the row of pins also have a variety of model specifications, according to the standard classification of electronic industry row of pin connectors:
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 pin, double-row pin, three-row pin, etc.; according to the packaging method there are SMD SMT (lying paste / vertical paste), plug-in DIP (straight / curved plug), etc.; according to the installation method: 180 ° with S said, 90 ° with R said, SMT with M said. .
Number of rows: single row, double row, three rows, four rows, up to four rows.
Number of pins: 02 to 80
Pins: straight, curved, SMT; pin size.
Size: length, width, thickness of external dimensions, row spacing.
Pitch: there are 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.54mm pitch.
Material: refers to the contact parts material and surface treatment, insulator material.
Packing: Tape Reel packing, roll bag, bulk packing.
Material: pin material: brass or phosphor bronze; insulator material: (PBT&NY6T&NY9T&LCP)plastic UL94V-0.
Surface treatment: gold-plated 0.8u, tin-plated, nickel-plated.
Processing process: the processing process of the row of pins is mainly: first according to the requirements of the brass (or phosphor bronze) processing of pins, and according to the requirements of the first nickel plating and then plating.
And according to the requirements of the first nickel plating and then gold plating, and then use the mold to process the insulator part, and finally in the special equipment according to the size of
Finally, the pins are set on the insulator according to the size requirements on special equipment.
Note: There are many factors affecting the price, usually the most influential are gold plating, pin length, etc. 
Example of pin row parameters
Features: single and double rows, straight and curved pins, pin spacing of 2.54mm and 3.96mm, various pin lengths.

The rectangular pins have a cross section of 0.8 x 1.6mm and a load current of 7.5A. The jacks have at least two independent shrapnel, four contact points, and a jack structure that prevents accidental insertion. 2.54 series square pins have a cross section of 0.64 x 0.64mm. The above two pins are designed with blunt corners and can be used in high frequency technology. The pin contact part is gold plated for corrosion resistance, low contact resistance and high reliability.
