Memory Connectors - PC Card Sockets

PC Card sockets, also referred to as PCMCIA connectors, are a popular type of memory connector that is used to connect a PC card – most commonly used to supports memory and storage devices – to a computer or laptop. The 1981959-1 is a type of PC card socket specifically designed for two-piece diskless configurations.

1981959-1 Construction

The 1981959-1 socket is a two-piece double side card edge PC Card socket with an activation force of 20 N. The card-end of the unit consists of 44 gold-plated contacts between two layers of contactor in a 0.050” inch pitch, with four mounting holes in a symmetric pattern. The socket-end has a .050” spacing to match the design of the card-end and is manufactured from brass, allowing for easier soldering and increased strength.

Electrical Specifications

The anode voltage used in the 1981959-1 is typically 5 volts, with a total current rating of 800mA. The contact resistance of the component is 7mOhms per contact group, maximum. The insulation resistance is 1 Gigiohm per contact group group, with a life expectancy rating of 5,000 cycles minimum. The operating temperature range for this socket is 0°C to +85°C.

Uses of the 1981959-1 Socket

The 1981959-1 socket is most commonly used in laptop computers to connect a PC card. PC cards are used in laptop computers to expand the capabilities of the machine, such as providing additional storage capability. They are also used in some types of medical equipment, where the need for reliable expansion capabilities are essential.

Working Principle

The working principle of the 1981959-1 socket is quite simple. When a PC Card is inserted into the socket, a current flows through the contacts on the socket and the contacts on the card. This current then triggers a mechanism that allows the device on the card to communicate with the computer, allowing data to be exchanged between the two.

Conclusion

The 1981959-1 socket is a popular type of memory connector that is used to connect a PC card to a computer or laptop. It is constructed from two separate components, and is designed to provide a reliable electrical connection between the card and the computer. The operating principle of the device is based on the flow of current through the contacts, enabling data exchange between the device and the computer.
