Because there are so many possible MT40 Absolute Position Encoder configurations, this specification was written to help you select the best configuration for your application.

Each encoder has 13 different specification parameters, and each parameter has several options. While the standard options are designed to fit most applications, custom options are available.

Determining a particular MT40 encoder model number will require specifying option codes for each of the 13 parameters. The section on the opposite page ("How to Order Your MT40 Encoder") will help you identify these parameters and show you how to put together the Option Codes to form the whole encoder model number for ordering. Separate sections on Parameters 1 through 13 show how to select the appropriate options for your application.

Below are some general construction notes that apply to all standard models. Along with the notes in the various parameter sections, they will assist you in specifying encoders for your application.
