Modular Angle Encoders With Magnetic Scanning
The ECM and ERM modular angle encoders from HEIDENHAIN with magnetic scanning consist of a magnetized scale drum and a scanning unit. Their MAGNODUR measuring standard and the magnetoresistive scanning principle make them particularly tolerant to contamination.
The attainable system accuracy depends on the eccentricity of the graduation to the drive shaft bearing, as well as the radial runout and wobble of the bearing.
Typical fields of application include machines and equipment with large hollow shaft diameters in environments with large amounts of airborne particles and liquids, for example:
Please use the specifications of your application to first select the scale drum and then the scanning head. You can see the associations in the table.
Please note that both the grating period and the line count must match. You will find this information as values in the attributes.
