Verify Sensor Mounting Surface Height
Verify that the distance between the mounting
surface of the sensor and the top of the scale is as
follows:
Tape scale after blue protective film is removed:
3.84 mm ± 0.15 mm
.
MicroE's Z-axis height gauge can be used to easily
verify this distance. (P/N: ZG-CET)
Use the gauge to check that there are no
gaps between:
1. The mounting surface of the gauge and the
mounting bracket, or
2. The bottom surface of the gauge and the scale.
Place the gauge in position and use the mounting
screws as guides. If the bottom of the gauge hits the
tape, you will see the gap between the gauge
bottom mounting surface and your mounting bracket
surface.
If you hand tighten the sensor mounting screws,
there should be no gap between the tape scale and
the bottom of the plastic gauge tool.
2.
Install Sensor
Install the sensor on the mounting surface
referencing the appropriate datum surface as
shown on the Interface Drawing. Use two M2 or
2-56 screws to loosely affix the sensor.
A benching edge is recommended to locate the
sensor to meet the mechanical mounting
tolerances. Refer to the Interface Drawing for
recommended location and height of edge.
Note: Tolerance for each axis is specified
independently, assuming nominal alignment in all
other axes.
