The Nemicon N20MA Series is a compact full magnetic absolute rotary encoder designed to deliver highly accurate position feedback in miniature motion systems. The encoder features patented energy harvesting magnetic sensing technology, allowing for battery‑less absolute position measurement with robust performance in environments with vibration, shock, and temperature variation. Its small modular 20 mm diameter package makes it ideal for integration into miniature servo motors, medical and laboratory equipment, linear actuators, and other precision automation applications.
The N20MA provides multi‑turn absolute position data with resolutions up to 24 bit and single‑turn absolute resolution up to 18 bit. It supports multiple communication protocols such as SSI, BiSS‑C, RS‑485, and SPI, offering flexible interfacing options for various motion controllers and industrial systems. Operating over a wide temperature range and capable of high shaft speed, the encoder delivers reliable absolute feedback without the need for external batteries, simplifying system design and improving maintenance.
