Angle Encoders Without Integral Bearing

The HEIDENHAIN ERP, ERA and ERO angle encoders without integral bearing are intended for integration in machine elements or components. They operate without friction and permit high accuracy. This makes them particularly attractive for high-precision angle measuring tables and precision devices in angular metrology. 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.

Product Overview

ERP 880	Highest accuracy Low error within one signal period thanks to the interferential scanning principle Housing with connecting cable as accessory
ERO 785	High accuracy DIADUR grating on circular glass scale
ERA 180	High shaft speeds up to 20000 rpm Sturdy design with solid steel scale drum Axial motion of drive shaft permissible up to ± 0.5 mm Typically used for direct mounting on high-speed spindles and ball screws
ERA 700 and ERA 800 series	For very large diameters up to 10 meters AURODUR steel scale tape High accuracy even at the junction of the scale-tape ends
