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

Rectangular Connectors are a type of electrical connector used to join two or more conductive components together, or to join one or more electrical conductors to a ground. Rectangular connectors come in a wide variety of physical formats, including Arrays, Edge Types, and Mezzanine (Board to Board). This article will discuss the 91920-21131 application field and working principle for each of these rectangular connector types.

Arrays

Arrays are a type of rectangular connector which use two mating pairs of contacts to form the connection, and each contact in the pair can be used for either signal or power transfer. The 91920-21131 array connector is made up of a basic four-pin single row right angle connector, with ROHS compliance. It offers a minimum electrical contact resistance of 20mΩ, and rated current of up to 4A. It is designed for high vibration and shock applications, with an operating temperature range of -40C to +105C. The 91920-21131 array connector features a one-piece metal shell, and snap-on locking mechanism for secure connection.

Edge Type

Edge type rectangular connectors are designed to fit into the edge of a printed circuit board, and are typically used for gaining access to digital signals, analog signals, power, or control. The 91920-21131 edge type connector features a two-piece metal shell, with a snap-in locking mechanism. It has a minimum electrical contact resistance of 6mΩ, and rated current up to 8A. The 91920-21131 edge type connector is also designed for high vibration applications, with an operating temperature range of -40C to +105C.

Mezzanine (Board to Board)

Mezzanine (Board to Board) rectangular connectors are designed to provide connections between two or more printed circuit boards, usually in high density applications. The 91920-21131 mezzanine connector features a two-piece metal shell, with a snap-in to lock mechanism. It offers a minimum electrical contact resistance of 18mΩ, and rated current up to 4A. The 91920-21131 mezzanine connector is also designed for high vibration applications, with an operating temperature range of -40C to +105C.In conclusion, the 91920-21131 rectangular connector provides a wide range of applications, from Arrays, Edge Types, to Mezzanine (Board to Board). It features a one-piece metal shell, with a snap-in locking mechanism for secure connection. The 91920-21131 offers a minimum electrical contact resistance ranging from 6mΩ to 20mΩ, and a rated current up to 8A. It is also designed for high vibration and shock applications, with an operating temperature range from -40C to +105C.
