Absolute Encoder Kit for 1100GTO **MADE TO ORDER** (PRICE TBD)

The photo above shows the Absolute Encoders installed on the 1100GTO-AE.

Absolute Encoders on both axes provide error-free tracking, software readable absolute position, customizable home and limit functions for robotic imaging.

We have chosen the Renishaw RESOLUTE Absolute Encoders as best-in-class for performance and reliability. Please read the technical information for more specifics.

This upgrade kit can be retrofit onto your 1600GTO or 1100GTO when you are ready to take advantage of its capabilities. The system will be tested as a whole prior to shipment to ensure that all components are functioning properly. In order to complete the assembly, a little manual dexterity is required to position the screws in a restrictive space. We will provide detailed instructions to guide you through this process.

IMPORTANT NOTE: Since the kit must be installed onto a 1600GTO or 1100GTO mount for alignment and testing at AP, it will only be available when we have a mount on hand that we can use. Typically, this will be limited to times that we are assembling that particular mount.


The GTOCP4 control box and associated power cable are required for all installations.
