LIMAX33 CP Shaft Information System Lift Positioning with Safety Functions for hoisting heights up to 260 m

  • Safe, absolute position detection up to 260 m and safety-relevant switching and control functions in one housing
  • High cost savings due to the reduction of components
  • Up to 3 pairs of safety relays and up to 13 safe inputs for SIL3 compliant controller transfer
  • Floor sensor possible (optional)
  • CANopen interface (DS406) for car position and parameter transfer, DS417and other safe interfaces possible
  • Scaleable functional safety architecture (e.g. solution for EN 81-A3 functionality with 2 safety relais)
  • Travel speed up to 10 m/s
  • Advantages of the magnetic tape technology: insensitive to dirt and smoke, flexible installation
  • EU-Type examination tested, SIL3 (TÜV-certified)
  • Floor sensor possible
  • Quick and easy installation
