Overview
FprEN 2997-014 is a CEN product standard within the EN 2997 aerospace connector series that specifies the characteristics of square flange mounted receptacles with integrated accessory. It applies to circular electrical connectors coupled by a threaded ring and addresses fire-resistant and non fire‑resistant variants across defined operating temperatures (−65 °C to 175 °C continuous, 200 °C continuous, 260 °C peak).
This draft standard (prEN 2997-014:2024) is prepared by ASD-STAN and, when approved, will supersede EN 2997-014:2016. It standardizes dimensions, mass, panel cut-outs, mounting methods, material and surface treatments, and class-based product characteristics.
Key Topics
- Scope & applicability: Square flange receptacles in the EN 2997 family; applies to classes listed in Table 3.
- Dimensions & mass: Detailed in Figure 1 and Table 1; dimensions and tolerances are in millimetres and apply after surface treatment. Mass values (without contacts) are provided per housing size.
- Panel cut-out & mounting: Panel cut-out dimensions and minimum clearances between adjacent connectors are given in Figure 2 and Table 2. Front and rear mounting options are specified (Figure 3).
- Material & surface treatment: Material and finish requirements are defined in Table 3 and address aluminium alloys and passivated stainless steel options with specified corrosion resistance.
- Design & marking: Formal designation and identity block rules are provided, including manufacturer marking and date codes. Identification characters and contact types are referenced.
- Classes & performance: Class definitions (WS, RS, S, SV, SE, SF) specify housing material/finish, salt‑mist resistance, contact type (crimp), vibration/fire performance and maximum operating temperatures.
Applications
This product standard supports selection, procurement and integration of connectors used in aerospace electrical systems where robust mechanical mounting and environmental performance are required. Typical applications include:
- Aircraft wiring panels where square flange receptacles provide secure panel attachment and easy mating.
- High-temperature zones or fire-protection systems where fire-resistant connector classes are required.
- Corrosion-prone environments where specified salt‑mist resistance and material finishes (nickel‑plated aluminium or stainless steel) guide material choice.
Practical considerations when using this standard:
- Verify the housing size and corresponding panel cut-out (Table 2) to ensure correct fit and clearance between connectors.
- Select class based on maximum operating temperature, salt‑mist resistance and vibration requirements.
- Refer to EN 2997-002 for contact arrangements and EN 3155 series for contact types when specifying delivered contacts.
Related Standards
- EN 2997-001 - Technical specification for the EN 2997 series
- EN 2997-002 - Specification of performance and contact arrangements
- EN 2997-008 / EN 2997-016 - Plug product standards
- EN 2997-009 - Protective covers for receptacles
- EN 3155-002 - Electrical contact list and utilization
Use FprEN 2997-014 as the reference when specifying square flange receptacles for aerospace designs to ensure compatibility across EN 2997 series components and compliance with material, dimensional and performance requirements.
