EnOcean has launched the ECO 200, third generation of its mechanical energy converters. When combined with a transmitter module, the result is an entire system for battery less wireless operations. This new pairing provides the basis for speedy and simple implementation of energy harvesting switching solutions in building automation, in industry and in household appliances.

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 ECO 200 is the latest advancement of these mechanical energy generators. It comes with more efficient energy conversion, less noise emission plus higher load capability. An additional benefit is simple installation. The transmitter is connected to the energy converter by spring contacts: no soldering is needed. There are four digital inputs that map up to four switching states. Wireless range is up to 30 meters inside buildings and 300 meters in the open.

Application possibilities for the energy harvesting wireless systems 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. Furthermore, the technology can be used to develop battery less vermin traps or battery less stop buttons in a city buses.
