ATEX RJ45/RJ11/USB connectors

Amphenol has released ATEX Ethernet and USB connectors for applications in zone 2 and Class I Division 2 explosive environments.

This ATEX range is an extension of the RJFIELD and USBFIELD ranges, incorporating Amphenol’s RJStop connection system for simple, rapid conversion of any standard ethernet cable into a connection with IP68 protection against shocks, dust and fluids.

These solutions have II3G ExnAIIT6X ATEX protection with temperature ranges from -40 to +60 °C for the RJ45 and RJ11 versions and -40 to +70 °C for the USB versions.

The metal cases have been strengthened to meet the mechanical resistance criteria of EN60079-15, including a 1 kg mass dropped from 70 cm. All the connectors are checked electrically in production to withstand a voltage of 500 V for 1 minute. The power capacity is 20 W at a maximum working voltage of 60 VRMS. The cable glands comply with standards EN60079-7 and EN60079-0 with II2G/D ExeII protection.

Three connector types are available — RJ45, USB and RJ11. These connectors have receptacles sealed in bushings that protect equipment interiors.

This 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.
