1 Data sheet RM44D01_10 Issue 10, 5 th July 2018 RM44 and RM58 rotary magnetic encoders The RM44/RM58 is an encoder designed for integration onto electric motors or other devices for shaft position and rotational speed measurement. The solid metal housing helps achieve the highest IP ratings, high EMC immunity, extended operating temperature range and the best possible shock and vibration resistance. Output signals are provided in industry standard absolute, incremental, analogue sinusoidal and linear voltage formats. vailable are resolutions of up to 13 bit absolute SSI and/ or 8,192 counts per revolution incremental for 5 V or 24 V power supply. With the provided magnet a system accuracy of ±0.5 is achievable. range of magnetic actuators for easy integration onto or into the shaft is also offered for easy system integration. Product range RM44/RM58C nalogue with a single sine/cosine cycle per revolution.
