AR49-M49M-K12H

AR49-M49M-K12H is an absolute reflective encoder module. The encoder is designed with a selection of serial communication protocols, with a dedicated electronic circuit designed for robust signal communication. The counter ASIC harvests the energy generated by the EH sensor for processing the rotational count and generates counting logic to non-volatile memory, which updates and stores the count. The entire operation of energy generation, counting, and storage processing is completed with limited energy and a short duration; hence, the kit encoder is suited for both low speed and high-speed measurement. Applications include stepper, BLDC, AC servo motor control, linear actuator, robotic engineering and automation, factory and automotive automation, automated guided vehicles (AGV), specialized medical and scientific laboratory equipment.
