»Wireless Ex«: self-sufficient command device
The new Ex command device EExF 95 RS SW from steute turns its operator into a source of energy. Inside the EExF 95 switch insert is a miniaturised electrodynamic energy generator. When the push-button is actuated it generates exactly the amount of energy necessary to transmit a radio signal.
The EExF 95 RS SW is thus independent of the power supply and can be installed without any cables. This permits universal application in potentially explosive atmospheres in gas-Ex zone 2 and dust-Ex zone 22. Variants for Ex zones 1 and 21 are in the pipeline.
Ex safety sensor: a »Mini« with a long operating distance
steute completes its range of safety sensors for potentially explosive atmospheres with a switch which is significantly different from the sensors previously available: the EEx HS Si 4. This device does not work on a magnetic switch basis, but uses three hall sensors to detect the actuator.
This active principle provides various advantages. Detection can take place in very small rooms: with dimensions of just 40.5 x 20 x 12 mm (l/w/h) the sensor has a very compact design, much smaller than the smallest EEx RC safety magnetic switches available so far. Moreover, the coded actuator is extremely compact, and yet a long operating distance is attained – another important feature.
Compact solenoid interlocks for explosible areas
With series EEx AZM 415 steute has introduced - as far as they know - the first solenoid interlock that meets the ATEX directive for explosion hazards arising from gas and dust and is certified correspondingly. Now this range of Ex safety interlocks is extended by a compact series.
