13 Installation procedure – extrusion
13.1 Protection for sealed linear encoders
IP53 requires installation with sealing lips positioned away from splash water in accordance with
EN 60529/IEC 60529.
For ingress protection to IP64, please see
section 14.8 on page
13.2 Fitment – general
Please note that fitment of the extrusion is independent of readhead mounting. For illustrative purposes
dowel pins are displayed, but the procedure for a datum edge is identical. Where neither an edge nor
dowel pins are available, begin by aligning extrusion mounting holes.*
Ensure the mounting faces are clean before installation.
* If a suitable reference edge or dowel pins are not available then we recommend that the extrusion is
checked against a dial gauge to ensure parallelism to the machine axis.
1
Place the encoder on the mounting surface and firmly push
against mounting edge/dowel pins. Position the encoder to align
mounting holes.
