Recommended Spacer Height
Spacers
Two spacers located diagonally are minimally
required. Some applications may require 4 spacers.
Spacers should be located 10 – 50 mm from the
corners of the receptacles to prevent excessive
mechanical loading on the interconnections.
If assembly will be subjected to vibration, spacers
should be located to prevent resonance, and
additional spacers may be required.
