Wireless switch for Ex zones

Wireless switch for Ex zones
The range of control devices and sensors from Steute offers an important interface between man and machine and the company's new wireless range in particular has been designed specifically for use in a variety of applications where secure transmission of signals is paramount.

The new battery-less RF 98 is an extremely robust and versatile wireless position switch that uses Steute's 'energy harvesting' principle to produce the energy required to transmit its wireless signal, which is done by converting kinetic energy (generated by the movement of actuating the switch) into electrical energy. The generated wireless signal, which uses the reliable MHz frequency, can extend from a minimum of 30m (internally) to a maximum of 300m (externally) and is insensitive to interference from external sources because the signal is transmitted within 80ms.

An IP67-rated Ex version is currently being tested and uses a robust metal enclosure to withstand high levels of mechanical stress. In accordance with the ATEX and IECEx directives, the EX RF 98 will be suitable for use in Ex zones 1 and 2, and 21 and 22.
