Protokraft introduces Viking Series 5 Port 10/100/1000Base-T Unmanaged Ethernet Switches to Improve Network Performance and Reliability in Harsh Environments
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 5x10/100/1000Base-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
