The MDM22 is a compact magnetic rotary encoder designed for high-speed and reliable position feedback in demanding industrial applications. With its small 22 mm diameter housing, it delivers accurate measurement while fitting easily into space-limited systems. Its fully encapsulated design provides excellent protection and ensures dependable operation in harsh environments.
The encoder uses magnetic sensing technology to provide stable performance without mechanical contact. As a result, it reduces wear and improves long-term reliability. The MDM22 supports AS and AC output signals, including 2 Vpp analog output and 0.5 Vpp analog output with RS422, allowing flexible integration with different motion control systems.
The MDM22 operates from a +5 VDC power supply and supports extremely high rotational speeds from 20,000 to 120,000 RPM. In addition, it operates across a wide temperature range from –40°C to +125°C, making it suitable for demanding industrial and high-performance applications.
With IP68 protection, the encoder withstands dust, water, and harsh environmental conditions. It also complies with EN61326 EMC requirements for reliable operation in industrial environments. The MDM22 is an excellent choice for servo motors, robotics, precision automation, high-speed machinery, and other applications that require compact, durable, and accurate rotary position feedback.
