PTM 215ZE – 2.4 GHz IEEE 802.15.4 Pushbutton Transmitter Module

1 General Description

1.1 Key Functionality

PTM 215ZE enables the realization of energy harvesting wireless switches for systems com-

municating based on the 2.4 GHz IEEE 802.15.4 radio standard including those supporting

the ZigBee Green Power standard.

PTM 215ZE integrates an NFC interface which can be used to configure device parameters

used for the radio telegram transmission.

PTM 215ZE 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 215ZE 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 appropriate

pushbutton or switch rocker.

When the energy bow is pushed down or released, electrical energy is created and a 2.4GHz

radio telegram according to the ZigBee Green Power standard is transmitted. This radio tel-

egram transmits the operating status of all four contact nipples at the moment when the

energy bow was pushed down or released. PTM 215ZE telegrams are protected with an AES-

128 signature based on a device-unique private key.
