General description
Basic functionality
PTM 215B enables the realization of energy harvesting wireless switches for lighting, build-
ing or industrial automation control systems using Bluetooth
®
low energy technology.
PTM 215B is mechanically compatible with the established PTM 210 form factor enabling
quick integration into a wide range of designs. Key applications are wall-mounted or porta-
ble switches either with up to two rockers or up to four push buttons.
PTM 215B 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 elec-
tro-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 tele-
gram transmits the status of all four contact nipples at the moment when the energy bow
was pushed down or released.
PTM 215B radio telegrams are protected with AES-128 security based on a device-unique
private key.
