The MA20 measuring wheel encoder provides simple, flexible and dependable position and speed feedback for conveyor systems. The two-in-one device combines a high-resolution optical incremental encoder and a highly precise measuring wheel. Capable of resolutions up to 25,000 ppr, the unit provides precise measuring results even at very low conveyor speeds. The system's HEX switch allows the user to select from 16 predefined resolutions between 100 and 25,000 ppr. These preset resolutions ensure that the multi-purpose unit meets a variety of application requirements and minimizes inventory requirements for manufacturers. Featuring continuously adjustable contact pressure, the unit eliminates measuring errors and ensures reliable surface contact without slip. Measuring 200 mm in circumference, the wear-resistant item is available in a variety of rubber hardnesses (Shore durometer between 40 or 70) to ensure optimatl adhesion to conveyor materials.
