Integral Shield TerminationThe connector shell has a platform to accept Band-It shield termination bands. The cable shield braid is attached directly to the connector. Save Labor, Reduce Weight and Improve EMI Shielding with Glenairs Micro-D Shielded Cable Assemblies Aerospace electronics systems require higher and higher levels of protection from radiated emissions. Glenairs fully shielded Micro-D cable assemblies meet this need. The cable shield is attached directly onto the one-piece connector shell and secured with a stainless steel BAND-IT clamp. These pre-wired, 100% tested assemblies meet the requirements of MIL-DTL-83513. An optional ground spring on the pin connector assures low shell-to- shell resistance. Available with a variety of wire types and shields, Micro-D shielded assemblies can be ordered in any length, either single-ended or back-to-back. Ground Spring and EMI Shielding Effectiveness A gold-plated stainless steel ground spring on the pin connector mating face offers substantial improvement in EMI protection. The graphs compare identical connectors tested with and without ground springs.
