SPS Drive 2017 will see one of the products steute will be presenting as its latest generation of wireless safety foot controls. These RF GFS 2 D (VD) SW2.4-safe triple-phase foot switches can be used in applications requiring Performance Level e (EN ISO 13849-1) and SIL 3 (IEC 61508) and are optionally available with an additional emergency-stop button.

Switchgears and sensors are abrasive, like cement dust and sand; they are corrosive, like fertilisers; or they are explosive, like all organic dusts. The characteristics of dusts often make high demands on the design of any switchgear they come into contact with, and as if this were not enough, the plants where these substances are handled are often located outdoors, where damp and extreme temperatures pose additional challenges to electric components.

  A three-stage wireless safe has been developed by steute, which enables foot control, on the basis of its safe wireless protocol sWave-safe. The steute Wireless business unit has presented its RF GFS 2 D (VD) switch at the SPS IPC Drives.

Withstanding temperatures of down to -60°C, these Ex magnetic sensors developed from the steute business unit ‘Extreme’ are cylindrical sensors of M20 diameter are cold-resistant down to -60oC and are also tested and approved according to ATEX and IECEx for use in gas Ex zones 1 and 2.

  The steute business unit ‘Extreme’ will be presenting a new series of Ex position switches developed especially for ‘Extreme’ applications and conforming to DIN EN 50041 dimensions, with or without safety function.

  The offshore industry knows no fewer than four factors which make extreme demands on switchgear. There is a risk of explosions; switches are exposed to high levels of mechanical wear and tear; the environment is corrosive; and it can be very cold.

According to DIN EN 50047 the light and robust Ex 97 switching devices look like a completely normal compact position switch with standard dimensions. However the construction details of the Ex 97 switching devices with plastic housings now available from the steute business unit ‘Extreme’ make these devices unique.

Extreme, a business division of steute, has developed a technology making the installation and operation of switchgear in explosive environments easier.  With Wireless Ex, switching devices are no longer connected to the evaluation units in the control cabinet by ex-compliant cables, but via a wireless protocol developed by steute.

The outstanding feature of our new RF 13 wireless switchgear series is immediately obvious: these switches are extremely compact in their design. In figures: with housing dimensions of just 49 x 40 x 21 mm, they are the smallest self-sufficient wireless switches for industrial applications currently on the market. And - what you cannot see - they are also characterised by a switching performance to match that of any microswitch.

One of the new products which the steute business division Wireless has presented at the Hannover Fair is an I/O unit enabling existing mechanical switching devices, e.g. cam switches in machine tools, to be integrated in wireless systems.

To avoid failures during routine work due to hot metal splashes that damage the power or signal cables, a wireless safety foot switch using Steute "sWave 2.4 GHZ-safe" technology has been chosen. It greatly increases reliability while being easy to install and flexible.

At the Hanover Fair 2015 (Hall 9, Booth G 06), steute will be taking a look at the (near) future of industrial production under the heading“The Integrated World” – in line with the motto of this year’s fair: “Integrated Industry – Join the Network“.

If the operator won’t come to the switch – then the switch must go to the operator. Bearing this principle in mind, steute has developed the RF HB-4CH wireless hand control, to be presented at the SPS IPC Drives for the first time. Development of this industry-compatible hand control was inspired by the steute business division Meditec, which provides high-quality controls for medical equipment. 

The new products which steute will be presenting at the SPS IPC Drives will include a series of foot controls especially developed for use in rough – or should we say extreme - environments. 

Open or closed? Position switches monitor the position of flaps and valves, as well as confirming the presence of tools or work pieces. These universal switching devices can also be used in extreme.

steute provides customers with its own range of offshore products especially developed for use in offshore, ship and port technology. Features of our devices include saltwater resistance, a robust construction, the necessary approvals and – where appropriate – Ex versions.

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.

The steute business field »Wireless« is continuing to expand the number of possible industrial applications for its innovative »energy harvesting« radio technology.

Totally independent from external power supply the design engineer can apply the wireless position switch Ex RF 95. And the user does not have to care about the loading condition of a battery, since there is a miniaturized electrodynamic energy generator in the switch insert of the Ex RF 95, which generates exactly that energy quantity necessary for the transmission of a radio signal.

The advantages of wireless communication are particularly obvious in the case of foot controls. The units can be positioned at will and there are no cables to trip over or restrict movement. With the RF GFI/ GFIS series engineers wishing to exploit these advantages not only have a new series of wireless foot switches at their disposal; they can also use a new high reliability wireless standard developed by steute.
