Installation Manual and Reference Guide
3.1.4 Design Guide
The following table describes the three basic mounting configurations for tape scale installation.
Also, see all guidelines that follow the table.
# Type of Installation Example
1 Machined Edge: Trench - Hand
Application Only
Trench:

6.1mm trench: applicator tool is not
compatible with 6.1mm trench, and
end caps cannot be used.

Max radius of 0.13mm required
between scale benching edge and
bottom of trench.

Benching edge must be parallel to
axis of motion to within .05/100mm.

Trench surface flatness to within
.003/10mm.
2 Machined Edge: Trench - Use with Tape
Applicator Tool
Trench:

12mm trench.

Max radius of 0.13mm required
between scale benching edge and
bottom of trench.

Benching edge must be parallel to
axis of motion to within .05/100mm.

Trench surface flatness to within
.003/10mm.
3 Temprary Straight Edge – Use with Tape
Applicator Tool
Temporary straight edge:

Use either your hands or the
applicator tool to install the tape scale
against a straight edge.

Minimum height of 9.53mm.

Benching edge must be parallel to
axis of motion to within .05/100mm.

Trench surface flatness to within
.003/10mm.

4.18±0.05mm: offset from tape scale
to temporary straight edge.
Guidelines:

MicroE Systems recommends using an edge as a guide to maintain straightness of the scale
during mounting. The edge can be temporary or permanent but must follow above guidelines.

Use the applicator tool for installation of scales, especially longer than 250mm, and for all
installations against a straight edge. For shorter scales, install by hand or use the applicator tool.
