<div><h2>Introduction</h2><p>The 91911-31531 is a rectangular connector array, edge type, mezzanine (board to board) connectors. This connector is designed to be used for data transmission and power transportation between two boards. </p><h2>Application Field and Working Principle</h2><p>The 91911-31531 connector is designed primarily for use in high-density computer applications. In computers, it is used for connecting microprocessors to corresponding motherboards and internal expansion cards. It is also suitable for Industrial, medical, and communication systems.</p><p>The working principle of the 91911-31531 connector is defined by a combination of two basic concepts: contact geometry and pitch matching. The 91911-31531 connector is based on the contact geometry concept, which states that the cross section of the two mating members should match exactly. This ensures that all contact points on the male and female connectors can be properly aligned for reliable electrical connections.</p><p>The second concept, pitch matching, states that the distance between each contact point should be equal. This ensures that the contacts do not overlap and that they can accommodate a wide variety of cables or wires. For the 91911-31531 connector, the contact density is high, accommodating up to 200 contact points in an area as small as 1mm².</p><p>The connector typically has the following features. First, the connector has a rectangular shape with a pronounced edge to ensure efficient connection between two boards. Second, the connector is designed to be rugged and durable, making it suitable for use in various environments with widely varying temperatures and humidity levels. Third, the connector has a low profile design, which minimizes its overall size. Finally, the voltage and current handling capability of the connector is suitable for many applications, including power, data, and signal transmission.</p><h2>Conclusion</h2><p>The 91911-31531 rectangular connector array, edge type, mezzanine (board to board) connector is a highly optimized solution for high-density computer applications. It is designed to provide reliable and fast connection between two boards, making it suitable for industrial, medical, and communication systems. The connector is based on two fundamental concepts: contact geometry and pitch matching. Additionally, the connector has a rugged and durable construction and a low profile design. The voltage and current handling capability of the connector makes it suitable for a variety of power, data, and signal transmission applications.</p></div>
