Overview

The prEN 3545-001:2025 standard, titled Aerospace series - Connectors, electrical, rectangular, with sealed and non-sealed rear, plastic housing, locking device, operating temperatures -55 °C to 175 °C - Part 001: Technical specification, is a key technical document developed by CEN (European Committee for Standardization) under the ASD-STAN technical committee. This standard specifies the comprehensive technical requirements for rectangular aerospace electrical connectors, designed with both sealed and non-sealed rear options, plastic housings, and integrated locking devices. It ensures reliable operation in extreme temperatures ranging from -55 °C to 175 °C.

This document supersedes the previous EN 3545-001:2008 and incorporates significant technical updates, including new mechanical endurance tests and compatibility assessments for zinc-nickel components. prEN 3545-001:2025 provides a definitive reference for aerospace connector designers, manufacturers, and quality assurance professionals who require durable, high-performance connectors suitable for demanding aerospace environments.

Key Topics

• Connector Types: Defines rectangular connectors with options for sealed or non-sealed rear enclosures to provide flexibility depending on application requirements.
• Materials and Construction: Specifies the use of plastic housings combined with locking devices to enhance durability and secure connections.
• Operating Temperature Range: Covers a broad thermal range from -55 °C up to 175 °C, ensuring performance in harsh aerospace conditions.
• Contact Arrangements: Details various contact configurations (from arrangement 02 to 16), supporting diverse aerospace wiring needs.
• Design and Dimensions: Provides specifications on connector dimensions, mass, and structural features like polarizing and attachment mechanisms.
• Test Methods: Incorporates extensive test protocols based on EN 2591 series test methods including mechanical endurance, temperature cycling, electrical continuity, climatic resistance, and chemical exposure.
• Quality Assurance: Outlines initial qualification, acceptance testing, periodic checks, and quality control processes to maintain standards in manufacturing and performance.
• Marking and Identification: Details naming and marking conventions for traceability and compliance in aerospace applications.
• Packaging and Storage: Specifies conditions to ensure maintenance of connector integrity from production to installation.

Applications

The prEN 3545-001:2025 standard applies primarily to aerospace electrical systems requiring reliable, durable rectangular connectors. Typical applications include:

• Aircraft Wiring and Electrical Systems: Used in critical onboard electronics and electrical harnesses where secure, sealed electrical connections are vital.
• Spacecraft and Satellite Systems: Suitable for harsh space environments that demand extreme temperature resilience and high mechanical endurance.
• Defense Aerospace Applications: Reliable connectors for military aircraft and systems that must withstand vibration, temperature extremes, and environmental stresses.
• Industrial and Avionics Equipment: Applicable for various aerospace-related industrial systems requiring ruggedized electrical connectors.

By adhering to this standard, manufacturers and users are assured of compatibility, performance, and safety in aerospace electrical integration.

Related Standards

prEN 3545-001:2025 references and aligns with numerous aerospace connection and test standards to ensure thorough validation and compatibility:

• EN 2591 Series - Extensive test methods covering visual inspection, contact resistance, electrical and mechanical endurance, climatic and environmental resistance.
• EN 2266-002 – Aerospace electrical cables operating under similar environmental temperature ranges.
• EN 3545 Series – Former versions and related parts of rectangular connector specifications.
• Related aerospace standards for plug-and-socket devices and electrical equipment within the 49.060 ICS classification.

These standards collectively support stringent requirements for aerospace electrical connectors, contributing to system reliability and safety.
