The new 2.5in CoreTech CI25 Series incremental encoder from Stegmann ships in just 2-3 days with any incremental count from 1 to 8192point/rev - without any price adder.

The new 2.5in CoreTech CI25 Series incremental encoder from Stegmann ships in just 2-3 days with any incremental count from 1 to 8192point/rev - without any price adder.

Up to 820kHz frequency response and a firmware generated marker pulse of 90 or 180 degrees provides reliable incremental feedback for speeds up to 10,000rev/min while maintaining marker width and synchronisation.

Alignment of electrical position to the mechanical encoder position is quick and easy with a simple setline.

These incremental encoders provide maximum operating speeds of up to 10,000rev/min.

They are designed to handle radial or axial loads of up to 90N, and reliably operate in temperatures ranging from -20 to +85C.

The CoreTech concept uses a minimum number of very sophisticated components to achieve maximum variety: a proprietary hybrid opto-ASIC and a small, unique code disk.

In contrast to conventional encoders with a continuous repetition of opaque and transparent fields on the code disk, CoreTech reads the information from one circular barcode track.

A second analogue sine/cosine track supplies additional data which, when synchronised with the data from the barcode track, results in high resolution and accuracy.

Both tracks are read simultaneously by a sophisticated sensor array on the hard-wired opto-ASIC.
