ATEX Ethernet connectors fit applications in zone 2 and Class I Division 2 explosive environments. The new range is a response to the current trend in the ATEX market of limiting the equipment in zone 1 (which is expensive) and installing it in zone 2, where constraints are much less demanding, leading to substantial reduction of overall plant costs.
This ATEX range is an extension of the RJFIELD and USBFIELD ranges, incorporating RJStop‚Â® connection system for simple, rapid conversion of any standard Ethernet cable into a connection with IP68 protection against shocks, dust and fluids.
The connectors have II3G ExnAIIT6X ATEX protection with temperature ranges from -40 ‚Â°C to +60 ‚Â°C for the RJ45 and RJ11 versions and -40 ‚Â°C to +70 ‚Â°C for the USB versions. The metal cases have been strengthened to meet the mechanical resistance criteria of EN 60079-15, including a 1 kg mass dropped from 70 cm. All the connectors are checked electrically in production to withstand voltage 500 V for 1 minute. The power capacity is 20 W at a maximum working voltage of 60 Vrms.
Three connector types are available: RJ45, USB and RJ11. They resist severe environments with IP68 ingress protection. The receptacles on their own are sealed in bushings, protecting equipment interiors.
The connector range has been designed for process monitoring and data acquisition in the oil, gas, chemicals and powder sectors, where ATEX compliance and reliability are essential characteristics.
