Mechanical energy converters pair up with wireless technology
EnOcean’s batteryless wireless technology harvests energy entirely from its surroundings – from light, differences in temperature or motion. Mechanical energy converters, for instance, can produce the energy needed to transmit a wireless signal just from the press of a button. The magnetic flux is suddenly reversed by a coil as soon as a spring mechanism reaches a snap-over point.
The ECO 200 energy converter is the latest advancement of these mechanical energy generators. It comes with even more efficient energy conversion, less noise emission plus higher load capability. A further benefit of the new-generation converter is its simple installation. The batteryless PTM 330 wireless module can be connected to the energy converter by spring contacts, with no soldering. This wireless module features four digital inputs to map up to four switching states. Additionally, an interface allows configuration of the content of the wireless telegrams during manufacture of a user device.
Like every EnOcean wireless module, the PTM 330 also has a unique 32-bit identification number to eliminate any overlap with other wireless sensors. Wireless range is up to 30 metres inside buildings and 300 metres in the open. With versions for both 868 MHz and 315 MHz the module is suitable for applications worldwide.
Application possibilities for the energy harvesting wireless ECO 200 plus PTM 330 system range from handheld transmitters, window and door sensors through to transmitters for access data to position switches or a variety of industrial switches. Handheld transmitters powered by the system can be used to control gates and garages, or to call a nurse from a hospital bed, for example. Another application that has already been implemented is wireless testing of cable harness in automobile production. The press of a button generates enough energy to determine if the individual components are properly attached to the cable harness
