Magnetic 17 bit absolute feedback with full information reading and a minimum 18 us response
The YMS35 series is a magnetic absolute encoder with 35 mm and 44 mm flange options. It reads single and multi-turn position, ID and full information, offers a read-write E2PROM with fault reset and single/multi-turn zeroing, and the magnetic principle tolerates dust and oil.
