Siko Draw-Wire Encoder SG121
Product Information
Universally usable wire-actuated encoder with measuring lengths of max. 12000 mm, robust design as well as precise and safe wire guidance; prepared for the attachment of various types of rotary encoders with 58 mm standard flange. In combination with a safety encoder from the PURE.MOBILE sensor platform, the wire-actuated encoder can also be used in safety-critical applications up to Performance Level PLd. Furthermore, the wire-actuated encoder can also be used in safety-critical applications up to Performance Level Pld for easy parameterization.
