Rectangular Connectors — Headers, Male Pins are used for a variety of designs and applications in the electronics industry. 77311-138-02 is a popular connector in this category that is used for quickly connecting two or more pieces of equipment. This connector is designed to be reliable and provide a stable connection in a variety of applications.

What is 77311-138-02?

77311-138-02 is a male pin header pin. The pin is made from threaded brass with gold or nickel-plated contact surfaces. It has a round 6.5mm diameter pin, and comes in four different versions, including a right angle form factor to accommodate boards that are stacked or have limited space. In terms of the length, the pin is 33.7mm long which allows the connector to fit into the rectangular hole of a printed circuit board (PCB).

Application Field and Working Principle

77311-138-02 is designed to be easy to operate and reliable in a variety of applications, including automotives, communications, CPU boards, and power supply boards. It is often used for bringing power and data signals in and out of the board as well as providing a reliable link and electrical continuity between pieces of equipment. The pin is installed into a PCB through the rectangular hole and then mechanically secured by removable mating connectors or mating headers placed over the pin.

The 77311-138-02 pin header works using a taper contact design principle. During assembly, the pins get wedged together which compresses them, thus providing better electrical contact and a secure grip which prevents accidental disconnection. This also helps to reduce the effects of vibration or impacts from the application environment.
