Orbis™
Rotary Magnetic Encoder Module
Orbis™ is a non-contact through-hole rotary encoder designed for applications where a typical OnAxis encoder cannot be mounted at the end of the rotating shaft due to space constraints.
Orbis™ through-hole encoder system consists of a readhead and diametrically magnetised permanent magnet ring.
Output signals are provided in industry standard absolute, incremental, and analogue sinusoidal (sin/cos) signals.
For BISS-C, SPI, SSI, Asynchronous serial and PWM communication please refer to BRD01 Data sheet.
For Analogue sin/cos, commutation and incremental outputs please refer to BRD14 Data sheet.
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 customization, with various board and magnet sizes to suit your application.
