Application Field and Working Principle

PC Card Sockets like the MI21-50PD-SF are typically used in portable devices, such as laptops, mobile phones, and multimedia players. The MI21-50PD-SF features an integrated contact system that allows a card to be securely locked into the socket. This contact system, also known as the QuickonT contact system, includes a special retention clip in the socket, which holds the card in place. The card is held in place by a resilient contact system, which operates on the principle of the lever mechanism.

When the card is inserted into the socket, the lever arm of the socket applies an force on the card. This force presses down on the card and applies a torque on the retention clip, which is inserted into the socket. The clip presses against the edge of the card, keeping it firmly in place. This mechanism ensures that the card is securely locked into the socket, and that its data and electrical connections are secure.

The MI21-50PD-SF is also resistant to shock and vibration, and can be used in a wide temperature range from -55°C to +105°C. This makes it suitable for use in extreme outdoor environments, like those found in aerospace and automotive applications. It is designed to support a maximum current of 10A and a maximum operating voltage of 300V. It has a maximum contact resistance of 10 mOhms and an environmental seal rating of IP67.

The MI21-50PD-SF is also RoHS compliant, making it a safe and reliable choice for a wide range of applications. It offers high reliability and excellent quality in a low profile design, making it ideal for portable devices. It can be used in a variety of applications ranging from medical equipment, telecom equipment, consumer appliances and aerospace systems. It is a great choice for applications requiring both high current and high voltage in a small form factor.
