Overview
kSIST FprEN 4165-018:2025 is a European aerospace standard specifying protective covers for electrical rectangular modular connectors designed to operate continuously at 175 °C. This product standard applies specifically to protective covers for 1, 2, and 4 module receptacles in series 2 and series 3. These connectors and their corresponding protective covers are critical components in aerospace electrical systems, ensuring reliable protection and durability under high-temperature operating conditions.
The standard is developed by CEN through the ASD-STAN Technical Committee and supersedes the previous EN 4165-018:2015 version, incorporating updates to normative references, marking requirements, and product designations.
Key Topics
Scope
Defines protective cover specifications for rectangular electrical connectors-series 2 and 3 modules used in aerospace applications.Design and Dimensions
Protective covers are detailed for different module configurations:- Single module covers with a maximum mass of 11 g
- Two-module covers (Classes W and F) with a maximum mass of 18.5 g
- Four-module covers (Classes W and F) with a maximum mass of 22 g
Precise measurements are provided in millimeters to ensure compatibility with the relevant connector receptacles.
Attachment and Sealing Features
Protective covers include:- Unlosable non-metallic cords attachable on sides or top
- Eyelets for secure mechanical fastening with specified hole diameters to ensure robust securing and easy handling
- Sealing elements to maintain environmental protection and EMI (electromagnetic interference) shielding capabilities
Marking and Identification
Mandatory marking on the cover includes:- Identity block as per designation clauses
- Date of manufacture (year-week format)
- Manufacturer’s name or trademark
These markings facilitate traceability and quality assurance in aerospace assembly and maintenance operations.
Applications
Aerospace Electrical Systems
The protective covers specified in kSIST FprEN 4165-018:2025 are essential in safeguarding modular rectangular connectors used in aircraft and spacecraft electrical wiring. These covers protect connectors against contamination, mechanical damage, and environmental impacts during storage, maintenance, and operational conditions.High-Temperature Environments
Designed for continuous operation at 175 °C, these protective covers ensure connector integrity in high-temperature aerospace environments, including engine compartments and avionics bays where thermal stress is significant.Modular Connector Maintenance
The covers enable safe handling and protection of connector interfaces when disconnected, preventing ingress of debris and preserving EMI characteristics, critical for avionics safety and performance.
