LIMAX2CP Safety Sensor shaft copying and safety functions in one housing

  • Detection of the absolute cabin position up to 130 m and safety-relevant switching and control functions in one housing
  • Numerous elevator and safety functions can be implemented: overspeed, final limits monitoring, ETSL, delay, door zone functions, unintented car movement UCM, inspection and start-up functions according to EN 81-20, 21 and EN 81-50, testing for unintented bridging of car and landing doors
  • Complete safety mechanism is electronically designed
  • Compact design, also suitable for the smallest installation spaces
  • High cost savings through elimination of components in the shaft
  • Safety functions can be adjusted  flexibly to the lift system on site
  • Advantages of magnetic tape technology: insensitive to dirt and smoke, quick installation
  • Quick and uncomplicated installation
  • EU type-tested according to EN 81-20, test according to SIL3 according to EN 61508
