Optical rotary encoders 42 General information and areas of application Sophisticated technology for high-resolution applications Optical encoders have an excellent cost-benefit ratio. This fully developed technology oers robust and well-sealed housings, permitting reliable measure-
ment with very high resolutions in a large number of industrial applications.The core of optical encoder technology is precisely segmented code discs with patterns in a circular arrangement. Well protected against external influences, the transparent and opaque sections alternate at defined intervals, dividing a beam of light directed onto a sensor into “digital” yes and no counting units. Signal sequences are generated, which form the basis for calculating the respec-
tive rotation angle. Combined with an intelligent follow-up electronic system, reliable calculation of angles, lengths and even speeds is possible. As two signal sequences A and B, oset by 90°, are scanned with each rotation, the electronic system also detects the “clockwise/counter-clockwise” direction of rotation due to the phase oset, with the advantage of enhancing the mechan-
ical and electrical safety and reliability of the system.The hollow shaft incremental encoders are simply slipped onto the shaft or spin-
dle. Solid shaft encoders are mounted with a flange and a connecting coupling. The absolute, opto-electronic scanning principle us-ing an angle encoder as an example Incremental encoders .
During incremental processes, an opto- electronic scanning unit tracks the uniform-incremental dividing pattern of the code disc and converts these into a number of electronic pulses that is pro- portional to the rotation. In the event of a voltage drop, however, the measured value is lost – the incremental encoder requires a reference operation. . 12 2 . 22 . 32 . 42 . 52 . 6 2
Light module Code disc with incremental or absolute patterns (light transparency) High resolutions, a clever housing concept, func- tional overall design with simple slip-on mounting and locking: The opti- cal SIKO encoders are excellently equipped for demanding measuring assignments The opto-elec-tronic scanning unit (here in the IG06) converts light pulses into digital signals. 2 RotoLine | 2.2 Optical rotary encoders www.siko.de
