Bluetooth Pushbutton Transmitter Module SR-SBP2801K4-BLE

SR-SBP2801-BLE enables the realization of energy harvesting wireless switches for lighting, build- ing or industrial automation control systems using Bluetooth® low energy technology.

SR-SBP2801-BLE is mechanically compatible with existing switch elements enabling quick integration into a wide range of designs. Key applications are wall-mounted or portable switches either with up to two rockers or up to four push buttons.

SR-SBP2801-BLE pushbutton transmitters are self-powered (no batteries) and fully maintenance- free. They can therefore be used in all environments including locations that are difficult to reach or within hermetically sealed housings. The required energy is generated by an electro-dynamic energy transducer actuated by an energy bow located on the left and right of the module. This energy bow which can be pushed from outside the module by an appro- priate pushbutton or switch rocker.

When the energy bow is pushed down or released, electrical energy is created and a radio telegram according to the Bluetooth® low energy standard is transmitted. This radio telegram transmits the status of all four contact nipples when the energy bow was pushed down or released. SR-SBP2801-BLE radio telegrams are protected with AES-128 security based on a device-unique private key.
