Overview
EN 4644-133:2016 is a CEN (ASD‑STAN) product standard in the EN 4644 aerospace connector series. It specifies the Size 3 receptacle for rack and panel applications used with the family of modular rectangular electrical and optical connectors with rectangular inserts. The standard applies to connectors rated for continuous operating temperatures of 175 °C (or 125 °C) and covers class C and D shell designs. The matching plug is defined separately in EN 4644-131.
Key topics and technical requirements
- Connector type and scope: Size 3 receptacle for rack and panel application, part of the modular rectangular connector family.
- Operating temperature: Continuous rating of 175 °C (or 125 °C) as per the EN 4644 series.
- Required characteristics (as specified):
- Dimensions and recommended panel cut‑out (illustrated in figures provided in the standard).
- Mass: maximum 60 g.
- Panel cut‑out coding: universal panel cut‑out with four coded areas (areas 1–4) and selectable hole drilling to match shell coding (codes A–T; Z = no coding pin). Coding uses coding pins on the shell to prevent mating errors.
- Housing / locking types: housing designation includes thread options (e.g., locking thread M3 × 0.5 or 4‑40 UNC) and polarization features.
- Marking: housing identification, date of manufacture (year‑week), and manufacturer name or trademark.
- Designation format: Example shown in the standard (EN4644-133 C M 000 G) identifies the standard number, shell class, housing type, polarization and panel coding.
- References: Technical specification and related performance/contact arrangements are given in EN 4644-001 and EN 4644-002; the plug is defined in EN 4644-131.
Applications and users
- Primary industries: Aerospace and defence systems where high‑temperature, modular rectangular electrical and optical connectors are required.
- Typical users: connector manufacturers, aerospace system integrators, electrical/mechanical designers, procurement and conformity officers, maintenance and repair teams.
- Practical uses: specifying compatible rack & panel receptacles for avionics units, ensuring correct panel cut‑out and coding to avoid mismating, selecting housings/locking types for installation and serviceability, and meeting marking and traceability requirements for production and maintenance.
