Rectangular connectors are used in many applications, including medical, industrial, automotive, consumer, and communication devices, among others. They vary in size, gender, and contact design. The gender of the headers are usually male pins and the contact design is usually crimp, solder, wire wrap, and pogo pin. Male pins are typically made of metal, plated tin to provide electrical and mechanical connectivity and prevent rust.

77313-126-72LF is an example of a rectangular connector in a 2 row, 126 position, with 72LF (low force) male pins. This rectangular connector has a single in-line (SIL) or single row style, that is designed for use in surface mounted applications. The connector is 8.2 mm in width and has a current rating of 3A. The contacts are 0.4 mm thick and have a temperature range of -55 to +105 degrees celsius, with a voltage rating of 50 Volts.

77313-126-72LF is designed for use in automotive, medical, and consumer electronics applications, where cost-effectiveness is the primary consideration. The 72LF male pins have a lower insertion force than typical headers, allowing for faster assembly time. Additionally, their low profile height is designed to prevent damage to the PCB during mounting. These connectors are designed to withstand temperature, voltage, current, and vibration, making them suitable for a variety of applications.

The working principle of 77313-126-72 LF is simple. In most cases, the male pins are pre-assembled on the printed circuit board (PCB) and fixed with a mounting screw. The contacts are soldered onto the pad on the PCB. The female connector is then inserted into the male pin, providing electrical and mechanical connectivity. The contacts inside the housing are pressure fitted and/ as inserted in the respective contact points on the PCB. The mated connectors then allow signals, power, and/or data to be transferred between them.

In summary, 77313-126-72LF is a rectangular connector with a SIL style, suitable for use in automotive, medical, and consumer electronics. The 72LF male pins have a low insertion force and a low profile height, making them convenient for automated assembly. The working principle of 77313-126-72LF is straightforward, requiring only the pre-assembly of the male pins on the PCB, followed by the soldering and assembly of the female connector.
