A2W Switches, Master Units, & Accessories

Omron A2W Switches and Master Units feature a 922.5MHz set frequency and a 50mV/m maximum transmission power rating. The Wireless Pushbutton Switches offer self-power generation due to the button's tactile operation, eliminating the need for a power supply, batteries, or maintenance. The Master Unit can obtain up to eight pushbutton switches and consists of a Sub-GHz band for reduced interference and better signal propagation for difficult-to-reach areas. The Omron A2W product family also includes a pushbutton holder, pushbutton strap, and a high-sensitivity magnetic-base antenna.
