Wireless Pushbutton Switch
A2W
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
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
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
