Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board): 91911-21225LF Application Field and Working Principle

Rectangular connectors are an important component of a wide range of electrical and electronics products, including PCBs, consumer electronics, car audio systems, and more. These connectors are used to provide electrical and physical connections between two (>2) different components and usually come in various shapes and sizes. One of the bestselling rectangular connectors for PCB applications is the 91911-21225LF. It’s a low-profile, right-angle connector for use in wiring board-to-board and board-to-component connections.The 91911-21225LF is part of the rectangular connectors’ arrays, edge type, and mezzanine range. It consists of a two-position, right-angle connector with built-in terminal blocks. The right-angle section allows improved connectivity and flexibility by allowing the connector to be mounted close to the board edge and away from other components. It also creates a tighter fit, effectively reducing the risk of wire getting caught in the connector. The built-in terminal blocks make it easy to install multiple connects without having to solder every connection individually.The 91911-21225LF has an exceptionally low profile of just 0.94mm. This reduced size allows improved board design flexibility and is ideal for space-constrained applications. The connector is also IPX7 rated, making it suitable for applications in harsh, wet environments. The 91911-21225LF is primarily used in board-to-component or board-to-board connections for low-power DC and signal applications. It’s widely used in wide range of applications, such as industrial control, robotics, automotive, audio equipment, passenger information systems, aviation, etc. It also works perfectly for all types of power routing and distribution in electronic circuits. The 91911-21225LF is a very versatile and reliable rectangular connector. It features two 0.2mm pitch, two-position, right-angle plugs and receptacles, and special long-life gull-wing terminals. The terminals of the connector are gold-plated and durable for improved corrosion resistance. The connector also has two mounting tabs with ground wires and a flexible tab-locking latch that provides a firm connection. The working principle of the 91911-21225LF is very straightforward and easy to understand. The signal and power contacts are connected to the board through pins, pads, or leads. The built-in terminal blocks are then connected to the terminals of the connector. When the connector is plugged in, the flexible tab locks the contacts firmly into place, creating the electrical connection. In summary, the 91911-21225LF is an efficient and versatile rectangular connector that’s suitable for a variety of applications. It’s part of the arrays, edge type, and mezzanine range and has a low profile and IPX7 rating for improved connectivity. The connector has two-position, right-angle plugs and receptacles and gold-plated terminals for improved corrosion resistance. Its simple working principle and easy installation makes it an ideal choice for PCB applications.
