Overview
EN 3372-003:2007 is a CEN product standard in the Aerospace series that defines the characteristics of square flange receptacles in the family of circular electrical connectors with bayonet coupling (scoop‑proof). It covers medium and high contact density connectors designed for demanding aerospace applications with continuous operating temperatures of −65 °C to 175 °C or 200 °C. The document specifies dimensional, mechanical and marking requirements for square‑flange mounted receptacles and references companion parts for contacts, plugs and protective covers.
Key topics and technical requirements
- Connector family and scope
- Square flange mounted receptacles within the EN 3372 circular connector family (bayonet ring coupling, scoop‑proof).
- Applies to classes defined in Table 3 (notably Class W and Class F).
- Dimensions and mass
- Detailed receptacle dimensions, tolerances and masses are given (Figure 1, Table 1). Dimensions apply after surface treatment.
- Panel cut‑out and mounting
- Panel cut‑out and mounting geometry for front and back panel mounting are defined (Figure 2, Table 2); includes minimum spacing calculations for multiple connectors.
- Materials and surface treatment
- Material and surface treatment requirements are specified (see Table 3) and differentiate connector classes (e.g., cadmium‑plated vs nickel‑plated aluminium alloys and salt spray performance).
- Connector classes
- Class W: cadmium‑plated aluminium, olive drab, 500 h salt spray, max continuous 175 °C.
- Class F: nickel‑plated aluminium, 48 h salt spray, max continuous 200 °C.
- Designation and marking
- Standardized designation format (example provided) and mandatory marking items: identity block, date of manufacture (year/week), manufacturer name/trademark.
- Reference to performance and contact arrangements
- Main performance characteristics, contact arrangements and compatible plugs/accessories are handled in EN 3372‑001, EN 3372‑002, EN 3372‑006 and EN 3372‑008.
Applications
- Use in aerospace electrical and avionics systems where robust, scoop‑proof circular connectors with bayonet coupling are required.
- Suitable for installations exposed to elevated continuous temperatures (up to 175 °C or 200 °C depending on class).
- Typical uses include airframe and engine compartment connections, harness terminations, and equipment panels requiring square‑flange receptacle mounting.
Who should use this standard
- Aerospace design and systems engineers
- Connector manufacturers and component suppliers
- Procurement and quality assurance teams specifying connector classes and finishes
- Test laboratories and certification bodies verifying conformance
- Maintenance and support organizations replacing or upgrading connectors
