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.

  • Robust design
  • Measuring lengths up to 3000 mm
  • Wire-actuated encoder for rotary encoder with 58 mm servo-flange
  • Variable mounting options
  • Lockable ventilation holes against condensation
  • Very robust measuring rope (stainless steel)
  • High tightness at the rope outlet
  • Also available as a safety version in combination with WV58MR rotary encoder
