55640-20211LF is a PC Card Socket which is a type of Memory Connector. It has a form factor of 56mm x 44mm, which is aimed at reducing installation cost and board space. It is typically used in applications such as environments that require a secure card grabbing and actuation mechanism, as well as in high vibration applications. It has a 78 pin female connector and a 655 pin male connector.

The 55640-20211LF has two principle working principles. The first is the actuation mechanism. This is the mechanism which enables the socket to secure the PC Card and prevent it from being released, and allows the card to be moved against a certain force. This is done via the use of spring arms, which move down when the card is inserted, and move back up when the card is removed. The second working principle is the signal coupling mechanism. This is the mechanism which creates electrical connections between the PC Card and the host device. Between these two mechanisms, the 55640-20211LF is able to securely connect the PC Card to the host device and provide reliable, low error communications between them.

The 55640-20211LF is normally seen used in applications requiring robust card grabbing features and reliable electrical connection. It is commonly seen used in medical devices, communications devices, metropolitan and trunk networks, as well as in industrial automation devices and instrumentation. It is especially popular in environments which require a secure card actuation system such as in high-vibration environments. Its 78 pin female and 655 pin male connectors also allow for a high degree of compatibility with all PC Cards and helps to expedite the design process.

The 55640-20211LF is also compliant to European Safety Standard EN60950 and UL10C and CSA 22.2 No.60950. It is also compliant to the RoHS Directive, and is lead-free and halogen-free. It also has an operating temperature range of 0 to +70 degrees Celsius, with a storage temperature of -40 to +85 degrees Celsius. With all these features, the 55640-20211LF makes a great Memory Connector choice for any application requiring a both a secure PC Card actuation system and reliable electrical connections.
