A new range of control devices from .steute UK & Ireland is designed specifically for use in potentially explosive applications. The EX RF BF 80 is available in three enclosure sizes, housing up to three different control devices including single and double pushbuttons, mushroom buttons, selector and control switches and key-operated switches.

The IP66-rated EX RF BF 80, which has been tested to more than one million operations, is suitable for use in operating temperatures between -20°C and +60°C and, in accordance with the ATEX and IECEx directives, is suitable for use in Ex zones 1 & 2 and 21 & 22.

Like many control devices in .steute’s ‘Wireless’ range, the radio signal 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. The battery-less EX RF BF 80 also uses .steute’s ‘energy harvesting’ principle, which produces the energy required to transmit the radio signal by converting kinetic energy (generated by the movement of actuating the button or switch) into electrical energy.

The EX RF BF 80 is multi-network compatible, easy to programme via the receivers and can be mounted directly at the place of use without the need to feed or fix cables. It can also be used in conjunction with other .steute wireless control devices, even on a single machine, as signals are transmitted together with a unique identification code.

Further information on the EX RF BF 80 can be found at http://www.steute.co.uk, where a link to a ZVEI document offering support on integrating wireless products into automation installations is also available.
