PTM 215B – 2.4 GHZ Pusbutton Transmitter Module

1 GENERAL DESCRIPTION

1.1 Basic functionality

PTM 215B enables the realization of energy harvesting wireless switches for EnOcean sys-

tems communicating based on the 2.4 GHz BLE communication 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 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 2.4 GHz BLE standard is transmitted. This radio telegram trans-

mits the operating 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.
