Memory Connectors, particularly PC card sockets, are among the most commonly used connectors in computer systems and laptop computers. Due to their low cost and wide range of applications, they are found in almost every electronic system and device. The particular connector under consideration here is the MI21A-50PD-SF-EJL. This style of connector is typically used to connect a memory card to a computer memory system and enable information transfer between the two.

The MI21A-50PD-SF-EJL connector is a 50-pin socket with a Plastic Dual In-Line (PDIP) footprint installation. The connector comes with a dual-action ejector to easily remove the memory card from the slot. It has a robust structure and clean terminations for a reliable connection. Its large pitch of 2mm ensures a secure mechanical fit. Its contact arms are 50 micron-thick tin-plated beryllium-copper alloy which provides excellent electrical performance and ensures a fault free connection.

In terms of its application field, the MI21A-50PD-SF-EJL are typically used in embedded computer and communications applications such as routing, switching, low power industrial, medical and military/aerospace applications. They are also used in instrumentation, networking and automotive fields. They are commonly used to connect electronic components for systems such as digital video recorders, GPS receivers, and advanced multimedia systems. This style of connector is also suitable for data storage applications as the mechanical interface allows for reliable read and write operations.

In terms of its working principle, the connector works in the following manner. When the memory card is inserted, the ejector template is driven by a latching mechanism which locks the card securely in the socket. The latching mechanism consists of an integral spring steel wire which exerts pressure against the card to maintain a secure connection. The contacts then make connection with the corresponding slots in the card, thus forming an electrical connection. Any data to be transferred is then passed between the memory card and the computer memory system. When the memory card is inserted, the contacts are in contact with a metal-oxide insulation layer which prevents corrosion and ensures the connection is maintained.

The MI21A-50PD-SF-EJL connector is a reliable way to connect a memory card to a computer memory system, whilst offering low cost and wide range of applications. It provides a robust structure and clean terminations for a reliable connection, and its contact arms provide excellent electrical performance. Its application field is wide, and is commonly used for data storage applications and embedded computer systems and communication applications. The working principle of this connector is straightforward yet reliable, and with the latching mechanism ensures a secure and durable connection.
