Orbis™ Battery Backup Multiturn

Orbis™ 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. Orbis™ also features an additional built-in self-calibration algorithm that improves encoder’s accuracy after installation.

 

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