Overview
EN 4165-018:2026 is a European product standard developed by CEN for the aerospace industry, focusing on electrical rectangular modular connectors. This part of the EN 4165 series specifies the requirements for protective covers designed for 1, 2, and 4 module receptacles of series 2 and 3, ensuring protection and integrity of electrical connector systems under continuous operating temperatures up to 175 °C. This standard addresses the specific needs for durable and reliable protection in demanding aerospace environments.
Key Topics
- Protective Cover Specification: Defines the characteristics and requirements for protective covers compatible with modular rectangular connector receptacles, particularly for series 2 and 3.
- Compatibility: These covers are intended for use with receptacles referenced in EN 4165-004, EN 4165-011, and EN 4165-025, covering both single and multi-module configurations.
- Design and Features:
- Covers for 1, 2, and 4 module receptacles
- Options for classes W and F
- Secure attachment with unlosable cords and EMI protection features
- Sealing capability for environmental protection
- Marking and Identification: Requirements for product marking include identity block, date of manufacture, and manufacturer’s identification, enhancing traceability and quality control.
- Performance Requirements: The standard references EN 4165-001 for technical and environmental performance, ensuring the cover maintains integrity at high temperatures and in harsh conditions.
Applications
EN 4165-018:2026 covers protective covers for rectangular modular connectors mainly used in the aerospace sector, where robust electrical systems are critical for safety and performance. Practical applications include:
- Aircraft Electrical Systems: Protection of module receptacles against dust, moisture, and electromagnetic interference when the connector is not in use, helping maintain reliability in avionics and power distribution networks.
- Spacecraft and Satellites: Ensures continuity of protection in modular connectors that may be exposed to extreme environmental changes.
- Military Aerospace Applications: Suitable for defense and aerospace platforms requiring high-temperature operation and durable protective solutions for electrical interfaces.
The adoption of protective covers as specified by this standard helps extend the lifespan of modular connector receptacles, reduces maintenance costs, and enhances safety by preventing contamination or mechanical damage.
Related Standards
EN 4165-018:2026 is part of a broader family of standards regulating modular rectangular connectors and their accessories in aerospace:
- EN 4165-001: Technical specifications for modular rectangular connectors, including general requirements and test methods.
- EN 4165-002: Covers performance specifications and contact arrangements for connectors.
- EN 4165-004: Specifies stackable mounting receptacles for 2 and 4 modules (series 2).
- EN 4165-011: Details flange mounting receptacles for 2 and 4 modules (series 2).
- EN 4165-025: Covers single module receptacles.
- ICS 31.220.10: Pertains to plug-and-socket devices, connectors.
- ICS 49.060: Relates specifically to aerospace electric equipment and systems.
By aligning with this and related standards, manufacturers and system integrators can ensure compatibility, interchangeability, and compliance with internationally recognized requirements for aerospace electrical connectors and their protective accessories. This standard is essential for maintaining robustness and reliability in modern aerospace electrical systems.
