SpaceNXT - AURORA Series
SpaceNXT - AURORA Series
High reliability hard
metric backplane
connectors specifically
designed and tested
for next generation
commercial space
applications
Smiths Interconnect’s SpaceNXT product portfolio provides
customers with a combination of highly reliable technology
and lower cost of ownership that enableoperators to
overcome potential market entry barriers while enjoying the
benefits of an established technology partner.
SpaceNXT Aurora Series offers a high reliability backplane
interconnect solution in a form factor widely accepted across
the market.
Tested to the ESA 3401 specification, SpaceNXT Aurora
Series has demonstrated its ability to survive the rigors
of most space applications, so it can be designed in with
confidence.The connector system also complies with the
widely used Hard Metric CompactPCI® specification, making
it easily integrated into existing platform architecture. It’s
footprint and envelope compatible with COTS 2mm, allowing
for use of the wide range of available accessories, such as
guide hardware.
This connector range delivers a broad set of features and
benefits to customers by addressing their high-reliability
connectivity needs. The Aurora Series features enhanced
gold plating with 1.27μm (50 μin) coverage on contact
mating surfaces, which provides consistent durability,
improved contact resistance stability, and greater resistance
to fretting versus alternate plating materials. Additionally,
Aurora meets customers’ performance requirements
without the need for lubricants, which can cause secondary
contamination, while offering electrical stability throughout
the product’s life. Developed specifically for the commercial
space applications, this Series is designed to perform
in operating environments that feature extremely harsh
conditions.
The SpaceNXT Aurora series incorporates rugged stamped
and formed contacts, making it the most cost effective
space grade, backplane connector solution on the market.
