The SPVQ4 Series comprises waterproof, high-contact-reliability detector switches that have a long stroke and can withstand severe conditions.
In recent years, mobile devices including PCs are experiencing an increasing need for high-volume data transfer for graphics, moving images, as well as audio transfer.
In response to this trend, the ExpressCard standard was launched in 2003 as the next generation PC card.
The ExpressCard comes in two standardised models; the 34mm wide ExpressCard/34 and the 54mm ExpressCard/54.
This the SCBA (pinheader portion)/SCBB (ejector portion) series connector, which is used with the next-generation ExpressCard, was developed to accommodate a two-card configuration through one slot.
This PC card connector uses top and bottom metal shield engineering, and boasts a robust structure, which is pressure and twist-resistant, while firmly holding in place two different card configurations.
Furthermore, the preset distance from the circuit board to the connector makes for a simple standoff design, which will be of value to engineers on the product side.
In addition, card-insertion and ejection uses the two-step lever-ejection system, which contributes to ease of operation.
With the card exit area down to 6.0mm and a function to prevent errors in card insertion, this connector offers a user-friendly feel and added convenience.
Alps has used its microprocessing, fabrication and structural design expertise to lengthen the pin-header insertion portion to approximately 6.0mm and with reflow soldering to increase connection stability.
Accordingly, by maintaining a high evenness between the pin and the circuit board after connection, the card and connector achieve high contact reliability.
