Industrial Ethenet unmanaged switch models feature multiple 10/100BaseT RJ45 Ethernet ports, while several also include an ST type fiber optic connection. There are units with an SC fiber optic connector. Plastic case models are designed for standard temperature range (-10 to +60 °C) while aluminum case models are designed for wider temperature range (-40 to +85 °C). These DINrail-mountable true plug-and-play devices automatically determine and remember devices connected to each port and only route messages through the appropriate ports, increasing speed and bandwidth.
