Jackscrew fixing replaces latches in robotics, satellite connectors
Robotics, satellites and motor sport applications can benefit from the Datamate J-Tek jackscrew fixing in high shock and vibration environments, says Harwin. The company says that customers are specifying 2mm pitch Datamate connectors with jackscrews, rather than latches or other fixing mechanisms, to ensure secure connection. As well as guaranteeing connector retention and signal integrity, the J-Tek jackscrew fixing is also being used to connect PCBs where space is at a premium. Autosport teams, for example, used to use plastic latches and are now moving to jackscrews for added security. Robotics is another example where repeated mating can lead to the latch wearing, so jackscrews are now commonly preferred, says the company. For satellites, especially miniature CubeSats, jackscrews ensure that the connection survives harsh operation conditions, but also save space.
The company recommends a torque of 21 ±2Ncm, to ensure devices meet EIA specifications for vibration severity. Jackscrews are available with all Harwin’s Datamate and Mix-Tek (mixed signal, power and coax) connectors.
