Note
: Tolerance for each axis is specified independently, assuming nominal alignment in other
axes.
6.1.2 Top Mounting
Perform the following steps to install sensor. Benching the sensor is the preferred method for
installation and the sensor will then not require an alignment. Refer to sensor information in
Section 3.0 System Overview
. For installing the sensor to a PCB, go to
Section 5.1.3 PCB
Mounting
.
Note
: A scale must be installed before installing the sensor. Refer to the
Optira Series
Encoders Tape and Glass Scales Installation Manual
for instructions.
Step
Action
1. Attach the FFC cable to the sensor ZIF connector J1 before installing sensor (see note
below about space restriction). Be careful when connecting/disconnecting the FFC to not
damage the connector.
Note
: Once sensor is mounted, there is not sufficient space to safely disconnect or connect
the FFC cable. As there is limited clearance between the ZIF connector and the scale
surface, it is recommended that the FFC be mounted to the connector prior to
mounting the sensor.
Tip
: For high mechanical stress environments, secure the FFC to ZIF connector using
non-conductive epoxy.
