Orient the polarizer so that the
polarizer latch is on the same side
as the inner wall (post side) of the
header housing.
Slide the polarizer over the
polarizing slot of the housing until
the latch engages the hole. Snap
off the tab at the break line next to
the housing. Using the remaining
polarizer, repeat the process for the
other housing location.
Note: For Post Shunts, contact Tyco Electronics.
Note: All part numbers are RoHS compliant.
The snap-in polarizer provides military polarization for low
profile headers. Installation of the polarizer is as follows:
