The Wireless pushbutton switch system has the following features.
• Up to eight Slave buttons (pushbutton switches) can be assigned to one Master Unit.
• Self-power generation by button operation eliminates the power supply for Slave buttons (pushbutton
switches). That allows you 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, and also makes it suitable for use in places with many obstacles.
• When you press the Slave button (pushbutton switch), you can confirm the success or failure of
transmission with the Master Unit by the color of Slave button's indicator. Therefore, even in places
where wireless communications are unstable, you can check the transmission and reception results
by retrying the operation.
• 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 8 Slave buttons can be registered to one Master Unit.)
Wireless pushbutton switches can be used for the following applications.
• Notifying ON/OFF information (e.g., people call, missing item information, work completion notifica-
tion)
• 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)
