High Speed with Signal Integrity eBook

robotics and aerospace systems provide a great example of hybrid and SWaP in connectors. Power requirements have evolved from 30 A to over 300 A or more in heavy lift type applications over the past decade, with some adding signal to provide telemetry, pulse wave modulation (PWM), or other data transfer.

contacts to prevent breakdown of the connectors. High voltage and current demands may create electrical noise inside the connector and require additional shielding. Shielding adds both size and weight to the overall solution through use of conductive braid, conductive shrink tubes, wraps, or ground terminations. In many cases, shielding is critical for maintaining device performance. With modern applications regularly demanding small portable form factors to get the job done, fitting a factory’s worth of computing power into a package with reduced size and weight can be a real challenge. Fusion of solutions utilizing proven designs and alternate materials can be a great asset when it comes to reducing size, weight, and power demands. Designers open to use of materials both in and outside of traditional specifications will find themselves with more solutions in their toolbox to address challenging environments.

Voltage can also present challenges in terms of power and signal delivery and affect overall size and weight. Voltages above those found in the MIL- DTL-83513 or MIL-DTL-32139 base specification will require additional contact-to-contact spacing and insulation methods such as individually shielded
