Orbis™ large diameter absolute rotary encoder

More Views

OrbisTM is an absolute, through-hole rotary encoder suitable for applications where a typical OnAxis encoder cannot be mounted at the end of the rotating shaft due to space constraints.

 

The encoder comprises a diametrically magnetized permanent magnet ring and a printed circuit board. Geometric arrangement of 8 RLS’ proprietary Hall sensors on a PCB enables generation of one period of sine and cosine signals per mechanical magnet revolution. Moreover, it also enables cancellation of third harmonic component that becomes non-negligible at low magnet ride height.

 

An adaptive filtering function ensures high resolution at low rotation speeds and low angle phase delay at high rotation speeds. OrbisTM also features an additional built-in self-calibration algorithm that improves encoder’s accuracy after installation.

 

OrbisTM through-hole measuring principle allows customisation, with various board and magnet sizes to suit your application.
