Draw-Wire Encoder SG31

robust design for rotary encoder mounting with 3000 mm measuring length

Very robust wire-actuated encoder in compact design for numerous applications including crane construction, stage construction, warehousing technology, etc., with a measuring length up to 3000 mm. Easy, universally changeable installation. 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.

Hint for mounting

When securing the wire it must be ensured that the wire is straight and vertical in relation to the wire outlet. Recommendation: Only select the starting position after an unwound length of approx. 5 mm. This prevents the wire hitting the end stop when it is rewound.
