SIST EN 3218-002:2009 is the Slovenian adoption of EN 3218-002:2006 from SIST/CEN. It specifies the performance and contact arrangements for rectangular connectors with metallic shells and screw-locking, as defined in EN 3218-001, for aerospace use.
What does SIST EN 3218-002:2009 specify?
SIST EN 3218-002:2009 covers the connector performance and the permitted contact arrangements for this family of rectangular aerospace connectors. The document is organized into clauses on scope, normative references, model coding, definitions, operating conditions, product standards, polarization and coding, contact arrangements, contacts, filler plugs, tools, marking, and assembly and wiring instructions.
The practical value of this structure is that it ties together identification, interface compatibility, cable selection, and installation guidance. A designer, buyer, or inspector can use the same document to check how a connector is designated, what mates with what, and which related standards apply.
What are the key requirements of SIST EN 3218-002:2009?
SIST EN 3218-002:2009 gives the rules that define a connector version, its mating compatibility, and the performance limits that matter in service.
Connector coding and finishes
Clause 3 defines model codes for the connector body and housing finish. The model codes identify a receptacle, plug, protective cover for plug, or protective cover for receptacle, while the finish codes identify anodized, cadmium-plated, or nickel-plated housings. In practice, this means the ordered part must be identified by both its form and its finish so the right parts are selected and matched.
Mating conditions
Clause 5.1 requires a plug to mate with a receptacle having the same finish. Clause 5.2 applies the same idea to protective covers. This matters because finish matching is part of the intended interface and prevents using incompatible combinations.
Termination types and cable use
Clause 5.3 sets the termination types: front-removable crimp contacts size 22, fixed solder contacts size 22, and rear-removable crimp contacts size 20, each with defined population codes. Clause 5.4 then limits the permissible cables by size code and gives section, closest American Wire Gauge (AWG), and insulation diameter ranges. In practice, the harness designer must choose a connector version that fits the termination method and cable dimensions.
Operating characteristics
Clause 5.5 groups the operating characteristics into electrical, climatic, and mechanical performance. It includes heating, insulation resistance, withstand voltage at sea level and at 1.1 kPa, permissible current per contact, operating temperature from − 65 °C to 150 °C, resistance to corrosion and fluids, and 500 mating and unmating operations. For users, this is the core check for whether the connector family suits the electrical load, altitude, temperature, and expected lifecycle.
Contact arrangements and intermateability
Clause 8 lists the contact arrangements by code, contact count, contact size, and mating-face view. It also states that equivalent size 20 and size 22 arrangements in the same housing size are intermateable, with current limited by the smaller contact. This is important when matching connector halves or when designing variants that must mate across different contact sizes.
Contacts, filler plugs, tools, marking, and instructions
Clause 9 links solder contacts to the inserts and points removable crimp contacts to EN 3155-022 and EN 3155-023. Clauses 10 to 13 direct the user to filler plugs, tooling, marking, and assembly and wiring instructions in related standards. In practice, these clauses tell the user where to find the parts and tools needed for assembly and maintenance.
What terms does SIST EN 3218-002:2009 define?
- Plug - The male connector half that mates with a receptacle.
- Receptacle - The mating connector half that receives the plug.
- Protective cover - A cover fitted to protect the connector when it is not in use.
- Crimp contact - A contact connected to the wire by crimping rather than soldering.
- Solder contact - A contact joined to the wire by solder and integrated with the insert in this family.
- Polarization and coding - The features that control how connectors are keyed so that only the intended mating position is used.
Who uses SIST EN 3218-002:2009?
SIST EN 3218-002:2009 is used in aerospace electrical and optical interconnection systems. It is relevant to connector designers, harness manufacturers, assembly technicians, test laboratories, quality teams, and buyers who need to specify the connector model, finish, contact arrangement, cable size, and related tooling.
In practice, these users apply it when selecting parts, checking interchangeability, preparing wiring, and verifying that a connector assembly meets the intended operating conditions.
What changed in SIST EN 3218-002:2009 from the previous edition?
SIST EN 3218-002:2009 corresponds to EN 3218-002:2006.
Which standards are used with SIST EN 3218-002:2009?
| Reference | What it contributes |
|---|---|
| EN 3218-001 | Technical specification and the definitions used by this part |
| EN 2265-002 | General requirements for electrical cables operating between − 55 °C and 150 °C |
| EN 2266-002 | General requirements for electrical cables operating between − 55 °C and 200 °C |
| EN 2591-209 | Test method for current temperature derating |
| EN 3155-022 | Specification for male rectangular crimp contacts, size 20, class R |
| EN 3155-023 | Specification for female rectangular crimp contacts, size 20, class R |
| EN 3197 | Installation of aircraft electrical and optical interconnection systems |
| EN 3218-005 to EN 3218-011 | Product standards for plugs, receptacles, covers, and extraction tools in this connector family |
| EN 4008-003 | Filler plugs for contacts used in electrical connection elements |
What does the SIST EN 3218-002:2009 document contain?
SIST EN 3218-002:2009 contains coding tables, operating-condition rules, contact-arrangement tables, and references to related product standards. Table 1 covers connector model and housing finish coding, Table 2 covers termination types, Table 3 covers permissible cable sizes, Table 4 covers polarization and coding, and Table 5 covers contact arrangements.
It also points to the standards for the contacts, filler plugs, tools, marking, and assembly instructions. That makes the document useful both for product definition and for checking whether the chosen connector family can be built and installed as intended.
