PTM 215B (ENOCEAN)

The PTM 215B from Enocean is a BLE pushbutton transmitter module with NFC interface. PTM 215B enables the realization of energy harvesting wireless switches for building or industrial automation systems communicating based on the 2.4GHz BLE radio standard. PTM 215B is mechanically compatible with the established PTM 21x form factor 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. PTM 215B pushbutton transmitters are self-powered (no batteries) and fully maintenance free. It 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.
