PTM 215B is mechanically compatible with the established PTM 21x form factor which allows 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. PTM 215B contains an electro-dynamic energy transducer actuated by a bow which can be pushed from outside the module on the left or right by an appropriate pushbutton or switch rocker. When the energy bow is pushed down, electrical energy is created and a set of Bluetooth Low En- ergy (BLE) advertising frames is transmitted. These advertising frames transmit the operating status of all four contact nipples at the moment when the energy bow was pushed down or re- leases. PTM 215B pushbutton transmitter modules are self-powered (no batteries) and fully mainte- nance-free. They can therefore be used in all environments including locations that are difficult to reach or within hermetically sealed housings. PTM 215B radio telegrams are protected with AES-128 (CBC) security based on a device-unique private key. PTM 215B provides an NFC interface according to ISO 14443 for configuration.
