RTLC40/FASTRACK : Scale datum
(Continued)
The datum clamp fixes the RTLC40 scale rigidly to the substrate at the location chosen.
The metrology of the system may be compromised if the datum clamp is not used.
The datum clamp does not need to be fitted adjacent to a reference mark.
It can be positioned anywhere along the axis depending upon the customer's requirements.

Using dispensing tip P-TL50-0209 apply Loctite 435
between scale and FASTRACK so it wicks underneath
adjacent to user selected datum location as shown.
NOTE: Drawing shows the scale datum adjacent
to the chosen reference mark.
NOTE: Only apply Loctite 435 in
these gaps to ensure best bond.
Loctite 435 will wick under the
