6. MECHANICAL SPECIFICATIONS
6.1. Connector A
Samtec’s QMS/QFS High Speed Interface series connectors were optimized for a 0.600” (15.24mm) stacking height and
standoff tolerances. Additionally, an optional 22mm top connector was developed to allow additional height above the
board. In both height options the bottom connector remains the same. An equivalent connector can be used.
It is permissible to use a OneBank connector for applications that do not require the signals or power in banks 2 and 3.
This connector consists of bank 1 pins 1 – 52 and its +5 volt power blade. All bank 1 signals and power are the same in
Type 1 and Type 2, so there is no such distinction when using the OneBank connector. It is recommended that all 3-bank
boards in a system be placed closest to the host CPU and then any OneBank boards be placed on the top or bottom of the
stack.
Note: Exercise caution when unplugging boards, especially with the smaller OneBank connectors. The connectors must
be kept in alignment and pulled straight apart to prevent damage to the exposed connector post.
