ATCA Family of Switches
C&K offers their ATCA family of switches, including the HDT, MDS, and SDS series
C&K has developed a variety of detect switches for use in Advanced Telecom Computing Architecture (ATCA) applications. Designated the MDS, SDS, and HDT series, the detect switches are implemented on the server blade as a safety mechanism to guarantee the blade is powered down, while ensuring no data is lost.
Switches in ATCA applications have traditionally been through-hole mounted, but these switches are surface-mount products providing customers with greater design flexibility. They meet the expanded temperature ranges and vibration requirements of ATCA applications in military and medical arenas.
While most ATCA applications are used in network and telecom servers, the detect switches are also being increasingly employed on advanced mezzanine cards (AMC) for improved data integrity in military, datacom, and medical applications, including black boxes and high-end ultrasound equipment.
