Hollow shaft encoders suit dirty environments
Blind hollow shaft encoders have just one point of potential access, which significantly reduces the potential for contamination by dust, dirt or water.
Features include an electronic zero position set and parallel or SSI absolute output.
A differential sensing principle guarantees high signal quality and noise immunity, and fewer electronic components and built-in monitoring functions enhance reliability.
The CA20 is the only known absolute encoder available today to reduce the form factor of 15bit absolute feedback to a 2in housing size while maintaining a direct read from the code disk.
The new 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 that have continuous repetitions of opaque and transparent fields on multiple tracks on the code disk, CoreTech condenses the position information into 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 higher resolution and accuracy.
Both tracks are read simultaneously by a sophisticated sensor array on the hard-wired opto ASIC.
