77311-120-20LF

77311-120-20LF rectangular connectors, also called headers with male pins, are one type of electrical connector commonly used in electronic products. They are designed with two rows of pins on either side of the housing, and are used to terminate a cable. The contacts on each side have a specific spacing, voltage rating, and current carrying ability. With a wide range of sizes, materials, and ratings available, it’s important to know the application and working principles of 77311-120-20LF connectors when selecting them for your project.

Application Field:

77311-120-20LF connectors are suitable for a variety of industries and applications, such as communications, consumer electronics, automotive electronics, industrial control, and instrumentation. Their primary use is to provide an electrical connection between two circuits, allowing for the transfer of power, data, or control signals. They are also used to provide grounding connections or transient suppression. The connectors meet UL, CUL, RoHS, and other industry standards for quality and reliability.

Working Principle:

The housing on a 77311-120-20LF connector contains two sets of pins, one male and one female. The male pins are soldered into the board and the female pins are inserted into the mating connector. The pins are held in place in the housing by barbs or small clips, ensuring a secure fit. The mating connectors are keyed so that they can only be inserted one way, and a locking mechanism is also often used to ensure the connector does not become loose or disconnected. In order for the connection to work, the two sets of pins must be properly mated.

To ensure proper connection, the two pins must fully engage and make contact with each other. This is achieved by using pins with specific size and spacing, which helps ensure that the male and female pins are compatible. Depending on the application, the pins may also be made of different metals or materials and have various plating options available. The voltage and current carrying ability of the connectors is determined by the size of the pins and the materials used.

In conclusion, 77311-120-20LF connectors are versatile, reliable, and easy to use, making them a popular choice for applications requiring electrical connections. Their two sets of pins are designed to properly mate and make contact, ensuring reliable connection for the lifetime of the product. With the wide range of sizes and materials available, they are an excellent choice for many projects.
