Absolute Machine-Guided Linear Encoder

Customer specific designs for the measuring flange can be supplied by AMO the measuring flange will be supplied by the customer for mounting the measuring ring at AMO (Type WMBA).

In this case the diameter for mounting the measuring ring can be calculated as shown in the table on the below and on page 4 and 5 of the catalog (see below). Special sizes with any number of pitches per revolution on request

The measurement scale of the absolute angle measuring systems with external scan can be realized in the following models:
■ standard measuring flange
■ customer specific flange
■ measuring rings
