Parallel Board to Board Vertical Receptacle and Plugs
The MICTOR connector family is based on the micro-strip concept of two rows of signal contacts divided by a center power ground plane. Motherboard and daughtercard compatible. Various mated heights are available for parallel board-to-board systems. There is a diskrete ground bus every 12.7mm [0.50in] of the connector length, which can be assigned to either power or ground in any combination. Redundant interfaces on every signal line provide added reliability. The connector system maintains a 50-ohm impedance and uses the solid ground bus between the rows of signals to provide low crosstalk and excellent high-speed signal characteristics.
