Rectangular connectors are one of the most widely used types of connectors in the market today. This is mainly due to their ability to transmit signals over far distances and with a high level of accuracy. 71991-326LF is a member of this family of connectors and is used for a variety of purposes. The article provides a brief overview of the 71991-326LF application fields and working principles.

71991-326LF is a special type of rectangular connector that can be used in a variety of applications including the interconnection of components on a printed circuit board (PCB) and other high-level industrial applications. It has a maximum current rating of 5A and an operating temperature range from -40°C to 85°C. It features a 20-position, 0.1-inch pitch header with gold-plated contacts and a female plastic socket with a vertical, machined mounting surface. It is designed to have a low profile of 3mm and is available in a variety of colors.

The primary application of 71991-326LF connectors is in the area of PCB interconnection. It is mainly used to provide a physical connection between a circuit board and its components. It is also used to provide power supply to various components. This includes providing power to logic circuits, memory circuits, external memory, signal interconnections, and various other devices. Furthermore, it can be used as a test point connector for functional testing of PCB assemblies.

71991-326LF connectors are also used in industrial applications. They are ideal for connecting motors, sensors, and relays. Additionally, they are used in automation equipment such as temperature controllers and power supplies. Further applications include LED lighting, automotive components, and industrial communications.

The working principle of the 71991-326LF connector is based on the principle of electromechanical contact. When a mating plug is inserted in the receptacle, the gold-plated contacts of the plug make contact with the spring-loaded terminals of the receptacle. This creates an electrical connection between the two components.

The gold-plated contacts of the 71991-326LF connector are designed to provide reliable electrical contact for high-speed digital signals. The contact spring-loaded terminals are designed to ensure a reliable connection with low contact resistance. The low profile of the connector allows it to fit into tight areas where other connectors may not be able to.

Overall, the 71991-326LF connector is an ideal choice for a variety of applications. It offers high performance, reliability, and low-cost installation, making it a preferred choice for many product designs. Furthermore, its wide operating temperatures range makes it suitable for use in a variety of industrial applications as well.
