Kingsport, TN, January 21, 2011– Protokraft today announced the availability of its Viking Series of 5 Port 10/100/1000Base-T unmanaged Ethernet switches to improve network performance and reliability in harsh environment applications. Protokraft has introduced the Viking Series of 10/100/1000Base-T unmanaged Ethernet switches with external D38999/19-35 connector interfaces for military, aerospace, industrial or utility applications where significant levels of shock, vibration and extreme temperature ranges are experienced. The Viking series Ethernet switches integrate five 10/100/1000Base-T Ethernet switch ports into the shell of a standard D38999/19-35 connector. These components are ideal for use in harsh environments where small size, weight reduction and resistance to harsh environments are valued.
Features
* 4+1 port unmanaged Ethernet switch for 5×10/100/1000Base-T switched interface ports
* Full duplex flow control and half duplex back pressure, symmetric and asymmetric
* Olive Drab Cadmium plating meets stringent corrosion resistance specifications
* Small size and weight (<8oz / 225g) for simple mounting and installation
* Unmanaged (Layer 2) Ethernet switch – no configuration required
* 5.0 or 12.0VDC power supply input – maximum < 5.0 Watts
* Shock, vibration and immersion resistant per Mil-Std-810
* Jumbo frame support in all speeds – 10/100/1000 Mbps
* Aluminum housings are strong, durable and light weight
* Cable link distances up to 100 Meters (EIA/TIA Cat-5E)
* Operating temperature range from -40°C to +85°C
* Auto sensing of half or full duplex operation
Protokraft Viking series unmanaged Ethernet switches consist of five 10/100/1000Base-T Ethernet switch ports integrated into a D38999/19-35 shell assembly. The external Ethernet interface to the Viking series switches is a D38999/19-35 connector enabling interconnection to external sealed and vibration proof cable assemblies. The internal electrical interface of the Viking series 5 port Ethernet switch is a 31 position MIL-DTL-83513 Micro D connector facilitating interface to internal switch, router or NIC cards and power supplies.
Designed to operate in harsh environments, these five port 10/100/1000Base-T unmanaged Ethernet switches feature excellent thermal characteristics, high tolerance to vibration and shock and corrosion resistant housings for exceptional EMI/RFI performance. Standard case operating temperature range is -40°C to +85°C, with a standard storage temperature range of -55°C to +100°C. They operate from +5.0 or +12.0 VDC power supplies.
