HEIDENHAIN Modular Angle Encoders with Optical Scanning
The angle gauges without integral bearing, ERP, ERO and ERA, are particularly suitable for high accuracy applications with limited installation space.
Because angle encoders are supplied without enclosure, the required degree of protection must be ensured through proper installation
Field of application:
– High-resolution rotary axes with high reproducibility
– Very high number of signal periods
– Small mounting space
– Small interpolation error and low signal noise
