2-1489841-2 Connectors, Interconnects

Memory Connectors - Inline Module Sockets

The 2-1489841-2 connectors are memory inline module sockets. These connectors are designed to allow the connection of memory modules such as DRAMs to a computer’s system board. They are available with a variety of pin counts and in an array of different materials and layouts. Additionally, they can be found with polarizing keys. Manufacturers often assemble them with self-aligning contact springs.

Application Field

These memory connectors are used in a wide range of different electronic equipment and components. Due to their compact form factor, they are ideal for small form factor systems such as laptops, notebooks, and tablets. The connectors are also used in solid-state drives, embedded systems, Raspberry Pi’s, and other instruments that require memory and storage.

Working Principle

In order to establish a connection, the memory connector’s contacts must first be mated with the accompanying memory module. The memory modules are typically inserted into the connector horizontally. The contact springs present inside the connector then flex outwards and make contact with the module’s electrical traces.

These connectors are typically divided into three types; male and female, and PCB mounted. Male and female connectors are usually made up of two parts; the memory module which is inserted into the connector and the connector housing which encases the module. PCB mounted connectors are constructed from a single piece of material and are directly soldered onto a printed circuit board. Once a connection is established, it is held in place by the compression forces generated by the connector’s mating surfaces.
