the appropriate datum surface as shown on the

Interface Drawing. Use two M-2 screws to loosely

affix the sensor.

Benching pins may be used to locate the sensor if the

system's mechanical tolerances are adequate. Refer to

the Interface Drawing for recommended locations and

heights of pins.

Verify Sensor Mounting Surface Height

Verify that the vertical distance between the reference

surface of the sensor and the top of the scale is

as follows:

Tape scale after blue protective film is removed:

3.09 mm +/-0.13

Linear or rotary glass scales: 2.93 mm +/-0.13

Check the height at a location on the scale where

there are no index or limit markers.
