Magnetic Belt Encoder


New HDMag flex magnetic encoders from Baumer allow great flexibility in mounting and accurate measuring under harsh conditions on large shafts such as those in torquemotors, generators, large drive units, azipod drive units (PODs), hoists and cranes, paper machinery, wind turbines, and hydroelectric plants. Available for shaft diameters from 300 millimeters (11.8 inches) to more than 3 meters (9.8 feet), the flexible magnetic belt can be buckled around the shaft using only two included screws by a single operator in mere minutes. That means that the HDMag flex encoders can be installed inexisting machinery without removing any parts.The non-contact, magnetic sensing principle ensures maximum resistance to shock, vibration, dust, dirt, liquids and condensation. 

HDMag flexmagnetic belt encoders are available either as incremental with HTL,TTL/RS422, or 1 Vpp SinCos outputs and up to 131072 lines per revolution, or as quasi-absolute with SSI data and additional incremental output signals. With IP 67 protection class, 30 g vibration, and 300 g shock ratings, these encoders are suitable for the harshest applications from-40°F to +185°F. The operational speed rating is up to 1850 rpm, making the HDMag flex series ideal for any large shaft application.
