Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) signifies a class of connectors primarily used as board-to-board edges and contacted at a low-frequency. The most common interface being used for these of connectors is the 91931-31115LF (LF for low-frequency).

Application Field: One of the most popular use cases for connectors of this class is for the interconnects in embedded system platforms; these connectors enable design solutions allowing signals and power to be communicated between different boards. This type of connector is popular in the market for its low-frequency speed, compact size, and reliable electrical performance.

Working Principle: 91931-31115LF follows the standard approach to accomplish the goal of interconnecting two boards. The contact system consists of 8-pins in a board-to-board array. The corresponding contact on the other board is crimped to the header pins. The contacts on the header pins are then soldered to it. Once the shunt is complete, the electrical connection is established. Typical applications for this type of connector can range from communication protocols (Ethernet, USB, etc) to power transmission.

The contact system follows the standard pattern for low-frequency connectors of this size. The pins are dimensioned in millimeters and use compliant pins technology. This technology ensures that the pins corrode and wear off at a consistent rate over time. The pins also maintain their elastic properties and reduce the chances of breakage and wear.

In summation, the 91931-31115LF is an ideal choice for low-frequency board-to-board edge connectors. Its 8-pin array, compliant pins technology, consistent electrical performance, and reliable contact system make it a great option for interconnects in embedded system platforms. The 91931-31115LF is an efficient connector that provides a great solution to board-to-board edge requirements.
