LIMAX2M Shaft Information System Absolute car position detection for hoisting heights up to 130 m

LIMAX2M is an absolute shaft copying system. Due to the absolute measurement, no further referencing of the system is necessary after commissioning or after a power failure; the absolute position is permanently available.

LIMAX2M is available in two versions. The standard version with RJ45 connection has protection class IP43, optionally LIMAX2M is also available with M12 round plug in protection class IP54 and is 100% compatible with the previous version.

  • Compact sensor design
  • With RJ45 connection (IP43)
  • Optionally also with M12 round plug (IP54) - in this version 100% compatible with previous version
  • Both versions are available with or without galvanic isolation of the CAN interface.
  • Extensive range of interfaces - compatible with almost all common elevator controls
  • Different measuring system resolutions up to 62.5 µm available
