At the POWTECH, the steute business division "Extreme" will be demonstrating new switchgear from its "Wireless Ex" range. The devices communicate via a wireless protocol and were developed especially for use in explosive environments (gas Ex zones 1 and 2; dust Ex zones 21 and 22). They all have the relevant approvals.

The wireless position switch Ex RF 96, which comes in a slim, rectangular design, monitors the positions of e.g. tools and work pieces in explosive zones, sending a signal to a wireless receiver. This receiver can be installed outside the explosive zone in a control cabinet, simplifying installation. 

The wireless inductive sensors in the Ex RF IS series come in a cylindrical design and diameters M 12, M 18 and M 30. Combination with the Ex RF 96 ST wireless universal transmitter makes them suitable for radio transmission, and the transmitter unit also provides them with the necessary power. 

Both series acquire the energy needed to transmit a wireless protocol via a longlife battery. This means that they can dispense with cables completely and can be mounted flexibly, even on moving or barely accessible components of machines and plants.

Both the Ex RF 96 and the universal transmitter are equipped with special Ex-protected lithium batteries which can be changed inside Ex zones 1/2 and 21/22. The battery inside the wireless universal transmitter in combination with the Ex wireless inductive sensor can achieve a lifetime of approx. 1000 days at six switching operations per minute. For the Ex wireless position switch, battery lifetimes of approx. 1000 days can be achieved at a switching rate of 1 x per second. The mechanical durability of the position switch also meets "Extreme" standards: over one million switching cycles. The wireless signal range is max. 450 m outdoors and up to 40 m indoors.

The "Wireless Ex" technology developed by steute creates additional flexibility during the construction of explosion-protected plants. It also minimises both effort and costs when installing switchgear in explosive environments.

Typical applications for the new steute Ex switchgear could be machines and plants, but also handling devices and conveyor systems used in explosive environments.
