The eXLink Ethernet and USB explosion proof connectors from Cooper Crouse-Hinds combine the safety of an explosion-protected connector system with the advantages of having a continuous communications infrastructure between the main, control and process levels of production plants. With the connector system, Ethernet-based communication systems can be secured in hazardous areas. This will allow companies to install and use the latest IT and communications infrastructures while still fulfilling all necessary explosion protection regulations and standards.

The safe transmission of data is guaranteed at all times using eXLink products, says the company. Independent tests have shown that the eXLink 4-pole + PA is safe to use up to 100MHz and with transmission rates up to 100Mbaud in accordance with the requirements of TIA/EIA-568-B.2, Category 5e. In many cases, Cooper Crouse-Hinds notes that the values were significantly lower than those of the limiting curves. The eXLink 4-pole + PA system can therefore be used in Fast Ethernet or Ethernet networks and for explosion-protected USB interfaces.
The eXLink range includes connectors, plugs, receptacles, inlets and elbows, which can be used for any instrumentation device or electrical apparatus. The plug connectors are used to connect and disconnect electrical equipment in hazardous environments - including actuators, motors, submerged pumps, liquid level sensors, floating switches - quickly, without compromising the safety or integrity of the electrical installation. The connectors allow users to maintain apparatus on a proactive or predictive basis, without using special tools and without having to isolate the apparatus from the mains or disconnect the terminals.
The company notes that conventional fieldbus systems are designed exclusively for data communication in process and manufacturing controls. The Ethernet communications protocol enables a continuous infrastructure between the main, control level and the process level. In hazardous industrial environments, eXLink connector systems can now replace conventional connectors found in the IT office environment. Therefore, in addition to high safety standards, this system also allows the real-time performance of Ethernet networks in hazardous areas. Controls can be adapted to suit changing production processes by allowing 'hot swapping'. Installing eXLink connectors is very straightforward, since Ethernet and explosion-protected components are both modular in their design.
This means that the plant's information architecture can be updated without having to change explosion-protected equipment, simply by replacing the components in the flameproof enclosures. Commercially available industrial components can be used here, as the explosion-protected connection to the network is undertaken by using the eXLink connector built into the enclosure, which also allows the hot swapping of devices without the user having to isolate them from the mains and without obtaining a hot work permit.
