2.54mm Pitch Round Pin Header Connector Waterproof Dual Row

• Female Header is a type of connector.

  This connector is widely used in electronic, electrical, instrument in the PCB circuit board, its role is in the circuit is blocked or isolated between the circuit, play a bridge function, take up the task of current or signal transmission.

  Usually used with row pin matching, forming a board-to-board connection; Or matching with the electronic wiring harness terminal, forming a board-to-wire connection; Can also be used independently for board to board connection.

  Because different products require different specifications, there are also a variety of sizes.

• Busbar is widely used in vehicle-mounted monitoring, instrumentation, Internet of things, new energy vehicles, LED display field, POS machine and scanner, lighting industry, security industry, electronic toys, household appliances, etc., providing the most reliable connection board to board and wire to board.

  The spacing can be roughly divided into 0.8mm, 1.00mm, 1.27mm, 1.5mm, 2.00mm, 2.2mm, 2.54mm, 3.0mm, 3.5mm, 3.08mm, 5.08mm

  The number of rows can be roughly divided into: single row, double row, three row, four row, etc.;

  The height can be roughly: H2.0, H2.2, H2.8, H3.4, H3.5 H4.3, H4.6, H4.9, H5.0, H5.7, H6.35, H7.1, H7.2, H8.5, H10.0, H11.0, etc."

  SMT(horizontal paste/vertical paste), plug-in DIP(straight insert/bend insert), splint, etc. (According to the installation method :180 degrees by S, 90 degrees by R, SMT by T)

• Y-shaped terminal: it has two contacts with the pin, but the terminal is 0.64mm thick. The pin can be lengthened and the rubber core can be overlaid to realize the secondary heightening of the pin.

  U-shaped terminal: there are 3 contact points with the row pin, the contact point is at the top of the product, the contact is stable to avoid transient break in the process of signal transmission. U-type leakproof tin terminal: there are 3 contact points with the pin, the contact point is on the top of the product, the contact is stable, avoid transient during signal transmission, prevent tin from leaking into the terminal.

  O-type terminal: there are three contact points with the row pin, the contact point is in the center of the product, the contact is stable to prevent transient interruption during signal transmission.

  O-type leakproof tin terminal: there are 3 contact points with the pin, the contact point is in the center of the product, the contact is stable to prevent the signal transmission transient, prevent tin leakage into the terminal.
