The 91900-21309 is an edge-mounting board-to-board connector that fits within the Rectangular Connectors - Arrays, Edge Type, Mezzanine category. It is most commonly used to join and connect two or more printed circuit boards together. It features a customizable design which includes signal connectors, high-speed differential pairs, power, and ground connectors, all made from precision machined metal for an increased rate of signal integrity. This allows the connector to be used in a variety of applications ranging from telecommunications to medical equipment to office electronics.

The 91900-21309 utilizes a specialized 90-degree ZIF (Zero Insertion Force) technology to allow for easy locking of the connector onto the board. This means that the connector does not require the need for force or insertion jigs and can instead be quickly snapped into place by hand. This makes the connector especially useful in assembly applications. Additionally, the 91900-21309 connector enables circuit board design to be enhanced through the addition of many options, such as flex, right angle configurations, machined or stamped contact terminals, impedance controlled or high-speed designs, and custom spring clips.

At its core, the 91900-21309 connector functions on the basis of commonly used electrical engineering principles. Electrons (or electricity) obey the laws of attraction and repulsion. Attraction allows electrons to pass through from one conductor to another, while repulsion prevents electrons from passing through by creating an electrical resistance. The 91900-21309 connector is made up of two main parts: a metal contact clip at the end of the connector, and a plastic insulating shield that covers the contact clip. The contact clip contains two or more metal contacts, which are separated by an insulator. In operation, when current flows through the contacts, electrons from the source material (which could be a circuit board) are attracted to the contact clip while electrons in the destination material (also a circuit board) are repelled away from the contact clip, creating a resolute connection between the two.

The 91900-21309 is an essential part of modern circuit board design fabrication and production. Its zero-insertion-force feature ensures ease of assembly while its adaptable design makes it suitable for a range of applications. The design is solid and reliable, helped by its adherence to the laws of electrical conductivity and its carefully constructed contact clip and insulating shield.
