Shielded Cable Assembly

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

specification 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-Master™ ATS

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.
