Application Note:
The cam (#230) and cam retainer (#220)
shown are minor modifications of the
standard parts (0020-84806 & 0020-84807)
and have been designed to secure
together via threads, instead of press
fit.
These parts are not inter-changeable
with the AMAT design and must be used
together.
Plansee also offers a one-piece,
graphite, top plate (Part No. 11684422)
that helps ensure consistent aperture
size and location for customers that
replace both sides during each PM.
