Series MBX – design guideline Working range (axial and radial) In mated condition, the two PCB connector have to be aligned within the dimension given for the axial and radial working range. HUBER+SUHNER recommends using guiding pins to align the boards within the connecting range and working range. Distance holders to maintain the axial misalignment within working range are also of benefit. The axial working range is ± 1.2 mm, the radial working range is ± 1.0 mm. In contradiction to the MMBX interface, the tilt of the adaptor is limited with MBX. The great advantage of this feature is that...
