Rectangular Connectors - Headers, Male Pins encompasses a diverse range of connectors, including the 77311-102-31LF. This discrete, two-piece, UL-recognized header is designed to meet a range of power distribution needs. Designed to be more cost-effective than competitive series, while providing similar performance, these headers feature a long-life contact system and can be applied to power supplies, motors, and other industrial applications.

The 77311-102-31LF is an insulated, low-profile, male-pin header. The surface-mountable header offers a wide range of versatility and features as well as eliminating the need for additional support. Measuring 15.41mm x 8.6mm x 4.81mm and featuring two (2) male pins, the 77311-102-31LF has a current rating of 5A at 20℃, with a voltage rating of 150V AC/DC. The UL-recognized device also offers a contact resistivity of ≤20mΩ, an insulation resistance of ≥50MΩ, and an operating temperature range of -55~105℃. In addition, the part is lead-free and RoHS compliant.

The 77311-102-31LF header is intended for busbar based systems, which serve as central power supply distributors and provide effective current and voltage distribution. By employing a busbar system, the current and voltage of each power outlet is regulated between the different outlets, resulting in improved performance and longer lasting product life. With the 77311-102-31LF, a higher current application can be created with a sufficiently low profile due to its cleverly designed contact system.

The contact system of the 77311-102-31LF consists of a male pin and a two-piece plastic collar. The plastic collar, which wraps around the male pin, acts as an insulator and provides structural stability. The male pin is made from tin-plated copper alloy and, due to its unique shape, a longer life contact is ensured – significantly reducing the possibility of contact degradation and corrosion during its lifetime in the application field.

The 77311-102-31LF is a highly versatile and reliable connector in the Rectangular Connectors - Headers, Male Pins category. Its innovative design, robust contact system, and low profile make it an ideal choice for high current applications. With a robust design, UL-recognized certification, lead-free construction, and RoHS compliance, the 77311-102-31LF is the perfect solution for busbar based systems across a wide range of applications.
