Angle Encoders

An angle encoder measures angular position at a level of accuracy significantly higher than a standard rotary encoder — typically within single arc-seconds. Suited for rotary axes and joints that directly affect a machine's geometric accuracy. Key Advantages • Among the highest angular accuracy on the market — down to single arc-seconds • Multiple form factors — integral bearing or modular • Wide hollow shaft (up to approx. 180 mm) in bearing models • High rotational speeds (up to approx. 20,000 rpm) in modular solutions • Magnetic scanning option available for enhanced environmental resistance Main Applications Tilt/rotary axes in CNC machines, industrial robotics joints, direct-drive motors, and rotary stages in semiconductor and metrology equipment. Main Series RCN/RON/RPN (integral bearing) · ERP/ERA/ECA (modular optical) · ECM/ERM (modular magnetic) More information https://www.heidenhain.com/products/encoders/angle-encoders
