SC-HG1 Series – Communication Unit for Digital Displacement Sensors – Panasonic Measurement Sensor

USD $ 333.73



Direct Connection to High-Speed EtherCAT [SC-HG1-ETC]

Acquires various numeric data from thru-beam type digital displacement sensor HG-T series and contact-type digital displacement sensor HG-S series and allows change of their settings.

  • Connects HG-T / HG-S series digital displacement sensors directly to EtherCAT!
  • Enables change of various settings all at once.
    Allows switching of controller’s internal banks.
  • Obtains high-accuracy measurement data without a program.
