Stahl Series 9851/5
ATEX Zone 2 Wi-Fi Access Point
Stahl Series 9851/5
The 9851 wireless enclosure system facilitates the utilization of standard wireless devices, such as WiFi access points, gateways with mobile communications, LoRaWAN, Bluetooth, or RFID readers, in Zone 2 without the need for approval for operation in hazardous areas. In contrast to solutions relying on metal Ex d enclosures, this system achieves a weight reduction of up to 70%. Mounting efforts are significantly decreased. Constructed from glass fiber-reinforced plastic, the enclosure allows for the emission of radio signals, eliminating the necessity for external antennas. Connection is established through a separate connection chamber, eliminating the need for access to the Ex nR enclosure and minimizing maintenance requirements.
Key Features
- Use of standard wireless devices in Zone 2
- Use of devices with internal antennas possible
- Simplified installation and maintenance thanks to separate connection chamber
- There is no need to regularly check the leak-tightness of the Ex nR enclosure section
- Low weight
