HEIDENHAIN's singleturn ECI 4000 features resolution of 20 bits and the EBI 4000 offers a multiturn variant with resolution of 16 bits.
HEIDENHAIN’s new rotary encoder series ECI 4000/EBI 4000 are modular devices without integral bearing and with a 90 mm hollow shaft. They enable you to replace the conventional toothed-belt drive for coupling a motor feedback system to torque motors. With fewer components, the new rotary encoders provide increased performance and guaranteed wear-free operation. Moreover, the set new standards in attainable control dynamics, reliability and functionality. The singleturn version of the ECI 4000 features resolution of 20 bits. As an alternative, with its EBI 4000, HEIDENHAIN offers a multiturn variant that features a revolution counter option with resolution of 16 bits and that is backed up by an external battery buffer. The new inductive rotary encoders consist of a scanning unit and the scale drum.
