Ethernet now in hazardous locations

08/18/2006


Three new products from Cirronet ’s SEM wireless Ethernet bridges line are UL-approved for use in hazardous Class I, Division 1 areas. The devices, SEM910-HL, SEM2410-HL, and SEM2411-HL, offer 10/100 base-T Ethernet connectivity and are suited for use in many factory and industrial settings.

Cirronet designed the products so that system integrators and network designers could take wireless Ethernet to very hazardous places, such as oil fields, gasoline refineries, and coal mines. Each product features enclosures with windows in order to easily view status indicators, and also a gas-tight RF connection system allows antennas to be mounted remotely from the SEM. A standard RJ45 Ethernet connector mates the SEM inside the enclosure, simplifying installation, and all operate at +9 V dc to +24 V dc.
