European foreword
This document (prEN 3155-075:2023) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 3155-075:2022.
EN 3155-075:2022:
— normative references updated;
— alternative design and view for female contact authorizing hood on front area side introduced;
— test sequence updated to ensure performance measurements of insertion loss (EN 2591-222) and
impedance characteristic (EN 2591-223) tests;
— document editorially revised.
1 Scope
This document specifies the required characteristics, tests and tooling applicable to female electrical
quadrax contacts, shielded, size 8, type E characteristic impedance 100 Ω, crimp, class R, used in elements
of connection according to EN 3155-002.
It is used together with EN 3155-001.
The associated male contacts are specified in EN 3155-074.
