Functional information
Product overview
The pushbutton transmitter module PTM 216B from EnOcean enables the implementation of
wireless remote controls without batteries. It transmits Bluetooth Low Energy (BLE) data
telegrams where the required energy is provided by a built-in electro-dynamic energy gen-
erator.
The PTM 216B product outline with key functional components is shown in Figure 2 below.

Basic functionality
PTM 216B devices contain an electro-dynamic energy converter which is actuated by an
energy bow (1). This bow is pushed by an appropriate push button, switch rocker or a simi-
lar construction mounted onto the device. An internal spring will release the energy bow as
soon as it is not pushed down anymore.
When the energy bow is pushed down, electrical energy is created and a BLE radio tele-
gram is transmitted which identifies the action (pressed or not pressed) and the status of
the four button contacts (2). Releasing the energy bow similarly generates energy which is
used to transmit a different radio telegram.
It is therefore possible to distinguish between radio telegrams sent when the energy bar
was pushed and radio telegrams sent when the energy bar was released.
By identifying these different telegrams types and measuring the time between pushing
and releasing of the energy bar, it is possible to distinguish between “Long” and “Short”
button contact presses. This enables simple implementation of applications such as dim-
ming control or blinds control including slat action.
