Blum TC50 High Speed Touch Probe

TC50 touch probes – Manufacture more productively with measuring speeds of up to 3 m/min

Please contact us for more info.


Universal touch probe systems for extremely fast measurements under the harshest conditions in medium and large machine tools. Superior precision and speed due to modern, multi-directional measuring mechanism with optoelectronic switch signal generation.

Wear-free, optoelectronic signal generation

  • The trigger signal is generated via shading of a miniature light barrier
  • Enables much higher measuring speeds and accuracies than comparable touch probes
  • Wear-free with long-term stability

High-precision, rotationally symmetrical measuring mechanism

  • Precise, non-lobing touch characteristics
  • Constant deflection forces
  • Spindle indexing is not required
  • No disadvantageous 3-leg principle with lobing effect
  • No highly sensitive switching elements

Reliable and proven transmission technology

  • Probe TC50: Infrared transmission
  • DUO-Mode: Sequential use of 2 infrared measuring systems with one receiver
  • Sequential use of up to 6 radio measuring systems with one receiver
  • TWIN mode: Simultaneous use of 2 radio measuring systems on one machine
  • Very long battery life
