ISO/IEC 11569:1993

ISO/IEC 11569:1993 defines mateability dimensions and contact number assignments for a 26-pole interface connector used in information technology and telecommunications equipment. It is relevant when engineering teams need a consistent physical interface definition for design review, product evaluation, and procurement decisions. By aligning connector geometry and contact identification, the document supports operational consistency, technical validation, and documented evaluation during integration or replacement of compatible equipment. In practice, ISO/IEC 11569:1993 helps reduce ambiguity where connector compatibility affects system assembly and conformity assessment.

ISO/IEC 11569:1993 standard overview

The technical scope of ISO/IEC 11569:1993 is centered on the connector interface itself: the mateability dimensions and the assignment of contact numbers for a 26-pole arrangement. That makes it a useful reference for engineers who need to confirm interface compatibility, prepare drawings, or verify equipment against a defined mechanical connection scheme. As a derived document connected to ISO/IEC 11569, it supports technical assessment and compliance workflows by clarifying how the interface should be identified and matched in documentation, testing, and procurement review.

Applications of ISO/IEC 11569:1993

ISO/IEC 11569:1993 is typically consulted in telecommunications and information technology hardware where a 26-pole connector interface must be specified or checked. It may be used in engineering documentation, laboratory evaluation, and manufacturing quality workflows to confirm connector orientation, contact numbering, and physical compatibility. Procurement teams may also rely on it when sourcing replacement components or comparing product specifications. In installation and maintenance environments, the reference can help reduce errors during equipment integration and support consistent assembly practices across technical teams.

Why ISO/IEC 11569:1993 matters

Accurate connector definitions are important for interoperability, and ISO/IEC 11569:1993 helps establish that consistency for a specific 26-pole interface. Clear mateability dimensions and contact assignments can lower the risk of misconnection, support verification activities, and improve testing consistency across suppliers or sites. For organizations preparing technical compliance files or conducting conformity assessment, the document offers a practical reference for validating interface details. It also helps procurement and engineering groups align on a common engineering specification before equipment is approved for use.
