New wireless controls versatile thanks to their modular design

Robustly designed safety switchgear for explosive atmospheres

The steute business field »Extreme« provides machine and plant engineers with the new 91 series of robust switchgear that has been designed especially for unfavourable environmental conditions : emergency pull-wire switches, belt-alignment and position switches, »Heavy duty« switchgear. Typical application fields are recycling plants, onshore terminals for bulk material, conveyor technology, and industrial plants for steel production and processing.

At the Hanover Fair, in addition to electromechanical wireless switchgear working according to the »energy harvesting« principle, the steute business field »Wireless« has introduced a new generation of wireless sensors using the sWave^® wireless protocol, developed by steute and running on the 868 / 915 MHz frequency band.

As an alternative to electromagnetic switchgear, non-contact sensors are increasingly finding their way into machine and plant engineering. steute already has a wide range of sensors working according to different principles and is now expanding its range further to include type RC 2580 magnetic sensors.

With the ES/EM 98 Extreme series, steute has developed new position switches with metal housings and normed dimensions in acc. with DIN EN 50041, suited to applications in extreme environments.

Wireless switchgear available with 868 and 915 MHz

Many mechanical and plant engineers are aware of the problem: in order to, for example, query a position, an inductive sensor needs to be attached to a moving machine part. The power and signal cables are extremely complex to lay, however, requiring drag chain cables or abrasive wheels.

With the new ZS 91, steute is expanding its range of emergency pull-wire switches to include a series which has been developed especially for heavy duty applications. Its enclosure is made of fibreglass-reinforced plastic and can withstand very high levels of mechanical wear and tear. Its release lever makes handling easier, while its optimised construction – in combination with the latest manufacturing technology – permits realisation of protection classes up to IP 67.
