Orbis™ true absolute rotary encoder

OrbisTM is a true absolute rotary encoder suitable for applications where a typical OnAxis encoder cannot be mounted at the end of the rotating shaft due to space constraints or if hollow shaft is required. The encoder comprises a diametrically magnetized permanent ring magnet and a printed circuit board. Geometric arrangement of 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.

An adaptive filtering function ensures high resolution at low rotation speeds and low angle phase delay at high rotational speeds. OrbisTM also features an additional built-in selfcalibration 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.
