Depending on the configuration, the self-powered module communicates using Bluetooth Low Energy or Zigbee Green Power
EnOcean has added a new module to its range of transmitter modules for battery-free switch applications. In addition to the already established PTM 535 for the EnOcean wireless standard and PTM 535Z for Zigbee applications, the new battery-free and wireless radio transmitter PTM 535BZ offers a combination of supported wireless standards in the 2.4 GHz radio band. In conjunction with the EnOcean ECO 200 harvester, PTM 535BZ enables the energy harvesting wireless switches communication based on Bluetooth Low Energy (BLE) or Zigbee Green Power (ZGP) radio standards. Integrated Near Field Communication (NFC) interface allows easy switching between the two radio standards depending on the application.
Combined radio standards and NFC for an easy integration
Until now, energy harvesting modules were designed to use only one radio protocol for data transmission: EnOcean, Bluetooth or Zigbee Green Power. The PTM 535BZ integrates the two 2.4 GHz protocols BLE and ZGP into one product, giving users the option of selecting one of these two protocols for transmission depending on their needs.
The use of NFC makes configuration much easier and also saves valuable time during installation. It also allows selection between BLE and ZGP radio protocol and defining all configuration parameters using an NFC-enabled smartphone or, alternatively, a PC with an NFC reader.
“The fact that the module supports two wireless standards means that the same end product can be used in various applications. This saves customers not only time but also costs, both being important factors when choosing a product,” said Matthias Kassner, Vice President Product Marketing, EnOcean GmbH.
Similar to the form factor of the existing PTM 535 and PTM 535Z models, the PTM 535BZ offers customers a fast integration into already existing mechanical designs. At the same time, there are almost no limits to the possible radio switching applications due to wireless and battery-free operation and the worldwide usability of 2.4 GHz radio solutions. These include stop buttons in public buses, mechanical door and window sensors or even mini switches for the private home, e.g. to switch household appliances on and off.
