A2W Wireless Pushbutton 22 mm Switches

Omron's A2W wireless pushbutton switches are designed without batteries to eliminate the need for maintenance

Image of Omron's A2W Wireless Pushbutton 22 mm Switches Omron's A2W wireless switches use a sub-GHz band for reduced interference and better signal propagation to difficult-to-reach areas. They have self-power generation, eliminating battery replacement at the individual switches and enhancing safety and energy saving in the Slave buttons (pushbutton switches). The A2W also have easy visualization of reception status using reception confirmation LEDs on the switch base, and a receiver unit capable of controlling eight switches at one time.

This system can reduce disconnection troubles occurring in the equipment using existing wired switches and can reduce time and expense when changing the layout.

Reliability is improved by wireless communications functions such as sub GHz band, master-slave communications, and reception confirmation LEDs.

Resources

Features
  • Up to eight Slave buttons can be assigned to one Master Unit
  • Self-power generation by button operation eliminates the power supply for Slave buttons, which allows users to carry Slave buttons
  • The transistor output from the Master Unit is a one-shot operation
  • Master-slave wireless communications are realized by sending ON/OFF data from the Slave buttons to the Master Unit and responding reception confirmation to the Slave buttons from the Master Unit
  • The radio frequency in the sub-GHz band used enhances the characteristics that radio waves reach and goes around, making it suitable for use in places with many obstacles
  • Press the Slave button to view the color of the Slave button's indicator to confirm the success or failure of transmission with the Master Unit so transmission and reception results can be checked even where wireless communications are unstable
  • A high-sensitivity magnetic-base antenna is provided to place the antenna in a position avoiding obstacles. This antenna is available when installing the Master Unit inside a control panel
  • Multiple Slave buttons can be assigned to the same output number of one Master Unit. (Up to eight Slave buttons can be registered to one Master unit)
Applications
  • Notifying ON/OFF information (e.g., people call, missing item information, work completion notification)
  • Instructions to automatic guided vehicles (e.g., instruction to stop)
  • Instructions from manned guided vehicles (e.g., instructions for opening and closing shutters or doors of warehouses)
  • Instructions to the machine (e.g., stopping, inching, opening and closing doors)
