PC card sockets, which typically operate at temperatures ranging from -55 and 105°C, are widely used in aviation and other industries where reliable connections and high-speed performance are required. The MI21A-50PD-SF-EJR91 model is one of the most popular memory connectors in the aviation industry and is ideal for applications demanding ruggedness, reliability and low insertion cycles.

The MI21A-50PD-SF-EJR91 memory connector is specifically designed to withstand the various challenging environments of the aviation industry, offering long-term reliability and excellent performance. In addition to being rated for ripple current up to 3 Amps, they are designed for EMI applications, and are made of self-lubricating thermoplastic in order to allow smooth insertion and extraction of the memory cards. The connectors are also equipped with gold-plated contacts, offering superior conductivity. It is an economical and efficient solution for commercial aircraft and military aircraft applications.

The MI21A-50PD-SF-EJR91 is a type II PC card connector that features spring-loaded contacts and a secure locking mechanism. It is designed to fit in tight spots and has a landing area that is specifically designed to reduce the risk of shorting. The card socket is available in vertical and horizontal configurations, making it incredibly versatile and easy to install. The gold-plated card edge connectors allow for easy handling and great contact retention. Additionally, it has a dynamic insertion force of 2.0 to 3.5 lbs and an extraction force of 0.5 to 1.5 lbs.

When looking at the working principle of this memory connector, it features the standard PC card contacts with three push-button latches to secure the card. These push-buttons need to be engaged in order for power to be transferred between the card and the system. To unlock the contacts of the card, there is a small clip located on the back of the card socket. When the clip is raised, the card will be released and power will automatically stop flowing. This ensures that the card is securely seated and only the intended card is making contact.

The MI21A-50PD-SF-EJR91 is ideal for a wide range of applications, including motherboard configurations, embedded systems, portable computers, servers, communications gear, and aviation systems. It is built with robust, mission-critical performance in mind and is capable of withstanding the rigors of the aviation industry. With its gold-plated contacts and secure locking mechanisms, it offers the reliability required by the aviation industry for system integration.

In conclusion, the MI21A-50PD-SF-EJR91 memory connector is ideal for applications demanding ruggedness, reliability and low insertion cycles. Its gold-plated contacts and secure locking mechanisms provide the reliability required for mission-critical operation in the aviation industry. It is a great choice for applications demanding high-speed performance and robust connections in extreme temperatures and environments.
