Memory Connectors - Inline Module Sockets

An inline module socket is an electrical connector designed to connect a memory device such as a RAM module to a motherboard. The inline module socket or IMC is used for both regular memory modules and expansion cards, while the card edge connector is used mostly for taller cards. The MM50-200B2-1E is a 2mm pitch, inline module socket used in common memory applications.

Application Fields

The MM50-200B2-1E is designed for a variety of memory applications such as in laptops, consumer electronics, and servers. Due to its small size, it can be used in both tight spaces and high-density applications. It is also designed to support high contact force, allowing it to withstand multiple insertion cycles and mechanical shocks.

The MM50-200B2-1E is designed to support various memory devices including: DDR, DDR2, and DDR3; SODIMM, RIMM, and DDR4; and memory modules from other vendors including Samsung, Elpida, and Micron.

Working Principle

The MM50-200B2-1E uses a special pin-and-socket design. The socket consists of two main parts: an outer housing and an inner onnector. The outer housing is designed with slots to hold the pins of the memory module. The inner connector consists of two rows of metal contacts that are spring-loaded and spread out when a memory module is inserted.

When a memory module is inserted, the contacts on the inner connector make contact with the pins of the memory module and connect the module to the motherboard. The spring-loaded contacts allow for a secure connection, and the outer housing holds the module in place. This design allows for reliability and durability, as the contacts remain in contact with the memory module pins even after multiple insertion cycles.

Types of Inline Module Sockets

Inline module sockets come in a variety of sizes and shapes. Some of the most popular types include the KK series (2mm - 4mm pitch), 50-200 series (2mm pitch), and LGA sockets (2502 - 5519). These sockets use different pin and socket designs, depending on the application.

The KK series is used in low-density applications such as consumer electronics, and features a pin-and-socket design. The 50-200 series is used in high-density applications such as servers and laptops, and features a quad flat no-leads (QFN) design. The LGA sockets feature a pin grid array (PGA) design and are used in ultra-high density applications.

Conclusion

The MM50-200B2-1E is a 2mm pitch, inline module socket used in common memory applications. It is designed for a variety of memory applications, including consumer electronics, laptops, and servers. It uses a pin-and-socket design with a spring-loaded inner connector, allowing for reliable connection and durability. Inline module sockets also come in a variety of sizes and shapes, including the KK series, 50-200 series, and LGA sockets.
