The new features mean that the switches are able to be operated automatically by NFC readers and smartphones at the same time as settings and the safety mechanisms are accessed through the "EnOcean Tool" app. Installed modules can remain in place through the process. The new PTM module remains in the footprint for easier upgrading and to fit into commonly found housings.
The new generation of PTM 215 switch modules operate using the EnOcean wireless standard in the 868 MHz frequency range and meet the latest EnOcean Alliance safety standards. The NFC interface adds extra setting options. The NFC devices still offer a combination of the ECO 200 electromechanical energy converter and an efficient radio module to provide an optimal energy yield at each keystroke and maximum transmission power.
"The integration of an NFC interface now makes our proven PTM switch module even more attractive, thanks to the very easy commissioning of the modules", says Marián Hönsch, Product Manager at EnOcean. "The commissioning of self-powered sensor and switch modules via NFC offers a simple solution for implementing a sensor system in a building as easily as possible and adapting it to specific requirements. We are working closely with the EnOcean Alliance to ensure that in future NFC will be used extensively in products and solutions of the EnOcean eco-system.”
A high level of data protection is assured when using the NFC switch and a reader. The NFC device and NFC reader must be within two centimetres of each other. Device keys for EnOcean radio communication through NFC can be changed but not read, which also increases data protection. Desynchronisation between the transmitter and receiver is impossible because the rolling code is sent with each transmission. The new PTM switch module is 100 % backwards compatible with the functional modes of the previous generation of the PTM 210/215.
