Overview
EN 4644-141:2016 is a CEN product standard in the Aerospace series that defines the size 4 plug for rack-and-panel applications in the family of modular rectangular electrical and optical connectors with rectangular inserts. The standard covers plugs designed for continuous operating temperatures of 175 °C (or 125 °C) and specifies mechanical, marking and designation rules for class C and D shells. The complementary receptacle is given in EN 4644-142. This size 4 plug can also mate with two size 2 receptacles, enabling flexible panel configurations.
Key topics and technical requirements
- Scope and usage: Specifies the size 4 plug for rack and panel applications within the modular rectangular connector family.
- Operating temperature: Rated for continuous operation at 175 °C or 125 °C, addressing high-temperature aerospace environments.
- Mechanical characteristics:
- Mass: 50 g maximum, useful for weight budgeting in aerospace designs.
- Housing types and threads: options include M (self-locking thread M3 × 0.5) and U (self-locking thread 4-40 UNC).
- Dimensions: detailed in the standard’s Figure 1 (see EN 4644-141 for drawing and axes references).
- Designation and marking:
- Example designation format: EN4644-141CM000 (includes standard number, shell class, housing type, polarization/locking code).
- Polarization and locking options: delivered with or without polarizing keys / locking hardware (codes such as 999 for none, 000 for unassembled polarizing key).
- Mandatory markings: housing ID, date of manufacture (year-week), and manufacturer name or trademark.
- Normative references and cross-references:
- Relies on EN 4644-001 (technical specification) and EN 4644-002 (performance and contact arrangements).
- Receptacle specification in EN 4644-142.
Applications and users
- Primary applications: Rack-and-panel electrical and optical connections in aerospace platforms where modular, high-temperature-capable connectors are required (avionics racks, flight control systems, environmental control units).
- Who uses this standard:
- Connector manufacturers and designers specifying size 4 plugs.
- Aerospace systems integrators and procurement teams requiring compliance and interchangeability.
- Test, maintenance and certification engineers ensuring marking, mass and mechanical compatibility.
- Product managers selecting components for high-temperature or mixed electrical/optical applications.
