MWDM Micro-D Shielded Cable Assemblies
Single-Ended or Double-Ended–These easy-to-order cable
assemblies eliminate the need for expensive assembly
labor. 100% tested and ready for use.
Now With Twisted Pairs–No need to create a procurement
specifi cation for Micro-D cables with twisted pairs. Glenair
177-740 cables are furnished with a full complement of
white/blue twisted pair wires.
Integral Shield Termination–The 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
Glenair’s Micro-D Shielded Cable Assemblies
Aerospace electronics systems require higher and higher levels of protection from radiated emissions. Glenair’s 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.
