Robust and compact SMT D-Sub connectors for use in space applications

C&K, a trusted brand of high-reliability connectors, announces the launch of its space-grade D-Subminiature surface mount termination (SMT) range of electrical connectors. The new SMT D-Sub connectors under CS-FR053 specification are primarily intended for aerospace engineering applications such as developing communication and network ports for satellites, spacecraft and launchers.

Reducing weight and making space savings on PCBs are critical requirements for connectors in space and military avionics applications, together with ensuring straightforward implementation and operational reliability. By utilizing SMT, C&K’s D-Sub connectors do not require plated holes to be drilled into the PCB, and free up one side for use by other components, resulting in a simpler, lighter design and a miniaturized footprint overall.

Constructed from a single part of machined aluminium shell, this latest series of connectors draws on C&K’s in-house technological expertise to achieve a smaller form factor than the traditional six-part copper-alloy stamped shell method. This means they can achieve up to 50% less weight compared to standard through-hole technology (THT) connectors. This construction technology also delivers better dimensional capability.

“With its combination of robustness, light weight and small form factor, the SMT D-Sub connectors are in a class of their own in the space and high-performance aerospace applications market,” said Rémi ANTOINE, Global Product Manager and Aerospace Segment Leader.

The D-Sub product lines conform to European Space Agency (ESA) standards and are qualified to the ESA/European Space Components Coordination (ESCC) code 3401. There are a large number of layouts available to serve most mounting configurations.

Gladys West - Pioneer of GPS
GPS and GNSS positioning technology is such an integral part of our lives today that we rarely stop to think about where it all came from. When we do, we usually picture men in white shirts and dark glasses hunched over calculators and slide rules. In fact, one of the early pioneers behind GPS and GNSS technology was Gladys West - a black woman.
