NOTES
1.
*
All microSI females have fluorosilicone interfacial seals installed.
Option not RoHS-compliant.
Left or right polarization is determined by looking at the male interface
with the LONG SIDE downward. Polarization matches the angled side.
Sidebands are on the non-angled side.
Captivated hardware is factory-installed and non-removable.
Factory-installed and non-removable. Refer to “Keying Hardware Options”
on page 61.
