4.0 Sensor Installation
This section contains instructions for installing the sensor.
4.1 Sensor Mounting Orientation and Tolerances
Refer to the following specifications when installing and aligning the Mercury II 5000 encoder.

4.2 Verify Sensor Mounting Surface Height
Step Action
1. Verify that the vertical distance between the reference surface of the sensor and the top of the
scale is as follows:

Tape scale/marker tape after blue protective film is removed: 3.09 mm +/-0.13

Linear or rotary glass scales: 2.93 mm +/-0.13
Note : Use MicroE’s Z-axis Height Gauges to easily verify this distance:

Blue Gauge - for use with tape scales (Part Number 409-00196)

White Gauge - for use with linear and rotary glass scales (Part Number 409-00197)
2. Use the correct gauge to check that there are no gaps between:

The mounting surface of the gauge and the mounting bracket, or

The bottom surface of the gauge and the scale
3. Check the height at a location on the scale where there are no index or limit markers.
4.3 Install Sensor
Step Action
1. Install the sensor on the mounting surface referencing the appropriate datum surface as
shown in the MII5000 Interface Drawings. Use two M-2 screws to loosely attach the sensor.
Note: Do not tighten the two M2 screws at this time.
2. Use benching pins to locate the sensor if the system's mechanical tolerances are adequate.
Refer to MII5000 Interface Drawings for recommended locations and heights of pins.
