Rotary Encoders Improve Robot Absolute Position Accuracy

Heidenhain introduces encoders designed specifically for the requirements of the robotics, medical and drive technology industries. The ECI 4000 absolute inductive rotary encoder is designed for hollow shaft diameters of 180 mm. This modular system with scale drum and separate scanning unit also features mounting characteristics for use in robots.

The rotary encoder, as well as the ECA 4000 angle encoder and the WMRA from AMO can improve the absolute position accuracy of the tool centerpoint on industrial robots by as much as 80 percent, according to the company.

The LIC 4000 absolute linear encoder and ECI 4000 inductive rotary encoder for hollow shaft diameters of 90 mm are designed to meet the medical industry’s need for gentle and safe handling of patients and equipment. 

The ECI/EQI 1100 without bearing (37 mm diameter) and ECI/EQI 1300 (65 mm diameter) inductive rotary encoders provide position feedback in a range of applications. They are designed to provide control quality and system accuracy as well as resistance to vibrations and electromagnetic influences. All variants support safety integrity level SIL 2, category 3 PL d.
