Autonics Magnetic Multi-Turn Absolute Rotary Encoder MGAM50S Series

The Rotary Encoder for Industrial automation

The Autonics MGAM50S series magnetic multi-turn absolute rotary encoders feature Ø50 mm size housings with Ø8 mm solid shafts. Magnetic encoders provide precision and accuracy even in harsh environments with shock, vibration, dust, or humidity (compared to optical encoders). The multi-turn type absolute encoders offer 23-bit (8,388,608) total resolution, with 10-bit single-turn (1024 divisions) and 13-bit multi-turn (8192 revolutions), providing accurate, cost-efficient solutions for any demanding application.

Working Principle of magnetic Encoders

• High Precision Even in Demanding Conditions : Unlike optical encoders which require perfect gaps between the disc and the optical sensor, magnetic encoders work by generating a signal as the magnetic field rotates. This allows higher tolerance for the encoders, allowing precise and accurate measurements in environments with shock, vibration, dust or humidity.
• Longer Service Life (Compared to Optical Encoders) : These magnetic rotary encoders which are products from Autonics company, do not contain sensitive components like optical encoders, allowing them to last longer in challenging environments. With higher shock and vibration resistance, and less chance of dust or condensation build-up, magnetic encoders inherently have a longer life cycle than its optical counterparts.

Cost-Efficient Sensor Chip Developed by Autonics

The magnetic sensor chip is self-developed by Autonics, allowing the encoders to be offered at relatively low prices compared to other brands.
