Radio position switch!

Radio position switch for rough environmental conditions

The steute business field »Wireless« introduces a new generation of radio position switches the series RF 98 with the mounting dimensions according to DIN EN 50041 (big standard switch). They are extremely robust with very versatile applications, with a completely new design.  They work using innovative »Energy Harvesting« principles and therefore do not require cables or batteries.

With its robust characteristics the new series is suitable for the most varied of applications in automation technology –  especially for areas where inconvenient environmental conditions occur. In the steute laboratories the impermeability of the new switchgear has been fully and properly tested. The result is that customer's requirement for IP 66 (jet of water) or IP 69K (high-pressure cleaner proof) protection classes are now available. The large range of temperatures from -20 °C up to +65 °C extends the application field of the new series.

There is a large variety of different actuators available for the different applications. As special variants there are Ex Wireless versions possible. The robust metal enclosure withstands high mechanical stress as Ex shock test have proven in the steute laboratories. These variants of the Ex RF 98 series were equipped to the requirements of gas and dust explosion protection (Zone 1 and 2 / Zone 21 and 22 per ATEX Directive) and will be approved accordingly in short time.
