The University of Wisconsin-Madison (UW) is building an infrared astronomical instrument called the Robert Stobie Spectrograph Near Infrared Arm (RSS-NIR), which will allow the Southern African Large Telescope (SALT) to see astronomical objects that are in the infrared spectrum of light – light too red to be visible to humans. This instrument requires cables that operate in three different temperature ranges: ambient (-10°C to +25°C; 14°F to 77°F), -40°C (-40°F), and -150°C (-238°F).
The research team came to HELUKABEL® USA with the need for a data cable that could be integrated to work with the RSS-NIR’s 1-wire™ network and also contained a shielded pair, a polyurethane (PUR) jacket, was cold-temperature rated, and capable of continuously flexing, since components of the RSS-NIR rotated between angles ranging from 10 to 100 degrees. After much work, the team finally chose the HELUKAT® Industrial Ethernet because of its ability to withstand the rigors of flexing 100,000 times at -40°C (-40 °F). Satisfied with the cable's performance and the high level of service from the HELUKABEL® USA team, the researchers at UW have added five additional cables to the RSS-NIR.
