Description

m&h RWP20.50 – Radio-Wave Touch Probes of the newest generation

m&h RWP20.50 radio-wave touch probes are available in two different frequency ranges. As a technology pioneer, m&h long ago introduced the first reliably functioning probe with radio-wave transmission of the measurement signals onto the market. The industrial frequency band of 433 MHz is still used today for reliable transmission of time-critical signals. The new radio-wave touch probe is still compatible with existing equipment in  the available 433 MHz version. Alternatively to this, the new m&h RWP20.50 radio-wave touch probe is also available with a new radio transmission technology in the frequency range of 2.4 – 2.4835 GHz.

The new bidirectional probe m&h RWP20.50 is characterized by its modular structure. Various measuring units, different extensions and cross-probes as well as a temperature sensor can be used. This makes it possible to optimally adjust the probe to future requirements and applications in the machine tool at any time. The development of further measuring units which can be used on the same system basis is planned for the future.

Design features
Specifications

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.

Proven SCS radio-wave transmission in the 433 MHz range

The radio transmission takes  place in the 433 MHz frequency band. 64 channels can be freely set on a digital display  on the probe and at the receiver. The patented SCS Technology (Self-Channel-Select) of  the microprocessor-controlled receiver responds by continuously checking surroundings for interfering signals. The receiver blocks interfering frequencies for further use.

MDR Technology (Multi Data Rate) in the 2.4 GHz range

The MDR (Multi Data Rate) technology makes it possible to transmit high data rates and large data sets in the shortest possible time. The spread spectrum transmission and a multiple transfer of the records ensure transmission reliability and a fast and trouble-free measurement process, as one expects from m&h.

ITE-technologie – intellegent trigger evaluation

Features:

  • Evaluate trigger signals.
  • Filtering machine vibrations and shocks.
  • No increase of the trigger force required.
  • No loss of precision.
  • No measuring errors due to incorrect switching.
  • Shorter cycle times by fast pre-positioning.

Benefits:

  • Shorter cycle times without loss of process reliability.
  • Pre-position with High-Speed (up to 50,000 mm/min) due to ITE technology.
  • One Touch Strategy for fast and precise probing (up to 2,000 mm/min).

Mechanical activision system

Features:

  • 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.

Benefits:

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

Functional and technological reliability

  • Very simple operation and installation of the operator.
  • Fast change of batteries (standard type) without tools.
  • Easy tip change and adjustment in the beating.
  • The transmission power is regulated on the machine.
  • Machine Retrofitting is possible at any time.

Robust and durable

  • Glass ring to protect the infrared diodes.
  • Housing made of stainless steel.
  • All seals made of viton.
  • Measuring unit protection by means of chip guard plate.
  • Probe completely sealed (immersion-tight) in acc. with IP68.
