Design features

SCS technology


  • Highest operational reliability through transmission protocol.
  • Permanent check of radio channels for interfering signals.
  • Automatic blocking of channels by Self Channel Select (SCS).
  • 64 radio channels in protected frequency range, proven worldwide.
  • 433 MHz transmitting frequency – internationally approved and high-penetration.


  • No machine downtime due to interfering signals.
  • High-penetration.
  • Automatic blocking of channels by SCS technology.

Mechanical activision system


  • Switch-on method AZ – activation of touch probe through pullstud (patented).
  • Switch-on method WS – activation through inner coolant or spindle air-blow (patented).
  • Switch-on method HSK – automatic activation in the spindle through mechanics in HSK shank.


  • No machine downtime due to false activation.
  • Safest activation systems.
  • No M-Function necessary.

Modular construction

  • Touch probe can be extended almost without limit.
  • Slim standard extensions in four different lengths can be combined.
  • For measuring tasks inside the workpiece.
  • Highest precision: measuring mechanism close to measuring point.

Trigger force freely adjustable

  • Measuring of thin sections with minimal measuring force.
  • Measuring of soft materials.
  • Measuring with large cross probes at max. measuring force.
  • No false signals during acceleration.
  • Easy adjustment from the front without dismantling (patented).

Performance and process reliability
