Two different mounting options are available. For a highly accurate alignment shoulder screws are used in the reamed 5mm diameter mounting holes. This option is recommended to ensure the correct alignment of the unit and the accuracy of the measurement.
For applications where this recommended mounting option is not possible to implement, a second non critical alignment option is available. We recommend that the flat back surface of the unit is used to align the unit against a flat aligned reference surface. The M4 clearance washers fit in the mounting recess and allow standard M4 mounting screws to hold the unit securely. This mounting option is not designed to ensure accurate alignment.
