Micro-D connectors are widely used in EMI applications; however,the shell-to-shell resistance of a mated pair can vary, resulting in inconsistentlevels of shielding effectiveness. Ground springs assure consistent shell-to-shellresistance for improved EMI protection.Ground Spring and EMI Shielding Effectiveness – A gold-platedstainless steel ground spring on the pin connector mating face offerssubstantial improvement in EMI protection.
