m&h Infrared Touch Probe IRP40.40-LF

m&h IRP40.40-LF - with constant very low trigger forces!

The new infrared touch probe has been specially developed for delicate materials and measuring tasks on thin, fragile workpiece geometries. The measuring mechanism, with constant very low trigger forces, can be fitted with different styli and spherical measuring tips from Ø 0.2 mm.

The new touch probe has a 2-sigma repeatability of 1 μm.

Application:
  • Determination of workpiece zero point
  • Determination of workpiece position
  • Control measurement of workpiece dimensions
Benefits:
  • With constant very low trigger forces
  • HDR (High Data Rate) transmission excludes interference of measuring from ambient light
  • Patented THERMO-LOCK® technology
About you
About your company
HDR - HIGH DATA RATE TECHNOLOGY

Features:

  • Different from worldwide line frequencies of 50 Hz or 60 Hz
  • Transmission frequency of 75 Hz
  • Extremely high data rate of 9600 light pulses/sec
  • Large transmit and receive angle with min. 120°- all around 360°
Benefits:

  • No interference from ambient light
  • Safest infrared transmission
  • Ensures process-reliable automation

PATENTIERTE THERMO-LOCK® TECHNOLOGY

Features:

  • Prevents heat transfer from the spindle to the probe
  • Delivers consistent, precise measurement results even by large temperature differences
  • HSK shanks with THERMO-LOCK® technology are available in various sizes

Benefits :

  • Precise measurement results even by large temperature differences
  • Eliminates uncontrolled expansion of the shank and probe body
Even at higher probing velocity and greater stylus deflection the probing forces on the m&h IRP40.40-LF remain constantly low - this characteristic protects your delicate, highly sensitive workpieces against damage.
