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.
  • Features & benefits
    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.

    AFS Technologie (Automatic Frequency Select)
    With AFS (Automatic Frequency Select) technology, the frequency ranges of this radio band are continually scanned and partial frequencies are automatically selected which are free of interfering signals. This not only ensures the system's own transmission with be fast and trouble-free, but also prevents interference form WLAN systems or other radio sources.
