Product Information
The Kontron Hartmann Wiener VME 3U Series 129 is a versatile backplane solution for VME and VME64x systems. The series is available with 2 to 21 slots, with each slot corresponding to 4 HP or 20.32 mm.
Depending on the selected version, the Series 129 supports manual daisy chaining or automatic daisy chaining with switching connectors. Both configurations are available with active or passive termination. The corresponding electrical circuitry is located at the ends of the bus lines and is mechanically positioned between the outermost slots to minimize space requirements.
The RF-optimized PCB design uses FR-4 material and complies with the ANSI/VITA 1.1-1997 base specification. A continuous chassis-ground surface and capacitive RF coupling between the rack and system ground support reliable operation in demanding applications.
Typical application areas include military systems, transportation, medical imaging, telecommunications, industrial controls, and aerospace.
