Features

Wireless Pushbutton Switch

"Wireless switch using sub-GHz band combines wireless reliability and ease-of-use in consideration of work environments"

  • Sub-GHz band for reduced interference and better signal propagation to difficult-to-reach areas
  • Visualization of impedance to wireless transmission because of damage or noise, using Master Unit error output
  • Visualization of Slave button reception status using reception confirmation LEDs
  • Transmission distance independent of the transmission position of the Slave button
  • Visualization of configuration using PC tools * that avoid erroneous ID registration
  • Visualization of signal quality in display and usage environments using PC tools *
  • 8 outputs with focus on decentralized control
  • Self-power generation eliminates battery replacement and enhances safety and energy saving in the Slave button
  • Slave button's shape allows easy use of buttons
