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

Rectangular connectors are a type of electrical connectors that provide interconnectivity for various systems and devices. They can be used in a variety of applications, from data and signal transmission to power and electrode connections. They are typically made up of two parts: an array of contacts in one member, and either an array of contacts, a conductive edge, or a mezzanine in the other.

Array Connectors

Array connectors are the most common type of rectangular connector. They employ an array of contacts that are spring loaded in sockets in the other member. This design allows for a high contact density and efficient use of space. They are typically used in applications where signal or data transmission is critical, such as in the assembly of computers. The contacts and sockets are typically gold plated for low resistance, noise-free signal transmission.

Edge Connectors

Edge connectors are a type of rectangular connector that uses a conductive edge on one member and an array of contacts in the other. The conductive edge is typically soldered or clamped onto a PCB (printed circuit board). They are typically used in applications where signal or data transmission is not critical, such as the power supply of a device. Edge connectors are usually more cost effective than array connectors and offer a lower contact density.

Mezzanine (Board to Board) Connectors

Mezzanine (board to board) connectors are a type of rectangular connector that employs a mezzanine on one member and an array of contacts in the other. The mezzanine is typically soldered onto a PCB. They are typically used in applications where there are multiple boards in the assembly, such as in networking equipment. The mezzanine design offers high contact density and is capable of carrying more current than an edge connector. The contacts are usually gold plated for low resistance and noise-free signal transmission.

The 91910-21111 is a type of mezzanine (board to board) rectangular connector. It is typically used in applications where signal or data transmission is not critical, such as in the power supply of a device. The mezzanine design offers high contact density and is capable of carrying more current than an edge connector. The contacts are usually gold plated for low resistance, noise-free signal transmission. It works by employing a mezzanine on one member and an array of contacts in the other. The mezzanine is typically soldered onto a PCB, while the array of contacts are spring loaded in sockets in the other member.
