Arrays, Edge Type, Mezzanine (Board to Board) 91901-31311LF Rectangular Connectors

91901-31311LF rectangular connectors are part of the Arrays, Edge Type, Mezzanine (Board to Board) family of connectors. As the name would suggest, this family of connectors can connect two circuit boards, or mezzanine boards, via a complex system of solder or press-fit contacts. A typical 91901-31311LF rectangular connector has twelve contact points embedded in the for edges of a polyamide body. This particular model of connector has a maximum voltage rating of 500V and a rated range of 5 to 35A. Each contact also has a rated temperature range of -40°C to 125°C.

Working Principle of 91901-31311LF Rectangular Connectors

In order to ensure the electrical continuity between two boards, the 91901-31311LF connector is equipped with an internal mechanism designed to resist stresses and vibration. Primary electrical and signal contacts feature heavy-duty locking ramps that allow a secure mechanical and electrical connection. The rectangular connectors also feature a secondary electrical contact system, which prevents loss of connection due to vibration or movement. This secondary contact system is achieved with a unique design that enables multiple contact points to ensure reliable conductivity between the boards.

Application Field and Design Considerations

The 91901-31311LF family of rectangular connectors is designed with both durability and compatibility in mind. This makes them ideal for a variety of applications, including industrial control systems, audio/video equipment, communication systems, automotive and shipbuilding electronics, and robotics projects.
