m&h Radio-wave Touch Probe RWP20.41

m&h RWP20.41 - do not compromise, proven radio-wave transmission from m&h!

The touch probe RWP20.41 has been designed for complex measuring tasks. Modular extensions enable measuring inside the workpiece or in deep cavities. The freely adjustable trigger force allows both triggering on very thin-walled workpieces at minimum trigger force and the use of heavy cross probes at maximum force.

  • Determination of workpiece zero point
  • Determination of workpiece position
  • Control measurement of workpiece dimensions


  • Proven and safe SCS technology
  • Reliable and unambiguous activation mechanisms ensure a smooth measuring procedure
  • Touch probe can be extended almost without limit
