This device is an industrial eco switch with two 10/100 Mbps RJ-45 ETHERNET ports (10/100BASE-TX) and four Single Pair Ethernet ports (10BASE-T1L). The switch enables ETHERNET communication at a bandwidth of 10 Mbit/s using shielded twisted-pair cabling over a maximum transmission distance of 1,000 m (approx. 3,280 ft). The automatic transmission rate detection (auto-negotiation) of the connected ETHERNET device enables simple plug-and-play operation. Connecting the SPE cable to the female connector with lever actuation is straightforward and time-efficient. Using Single Pair Ethernet significantly reduces the cost of integrating an Ethernet connection over long transmission distances. In particular, the use of existing cabling can significantly reduce the cost of connecting decentralized, Ethernet-capable sensors to an automation system. Another application is the networking of remote Ethernet devices using an SPE media converter (852-1705) and the 852-2112. This solution enables the substitution of DSL modems or fiber optic connections. Its compact design with a DIN-rail adapter makes installation in control cabinets easier and provides high heat, vibration and shock resistance.
