IEC 60297-3-104:2006 defines connector dependent interface dimensions for subracks and plug-in units within the 482,6 mm (19 in) mechanical structure series. It is relevant when teams need a dimensional reference for designing, selecting, or verifying rack-mounted electronic equipment that must fit together reliably. By tying mechanical interfaces to connector-related requirements, IEC 60297-3-104:2006 supports engineering documentation, product evaluation, and conformity assessment where physical compatibility and operational consistency matter.

What is IEC 60297-3-104:2006?

This document is a primary technical reference for the mechanical dimensions associated with subracks and plug-in units in the 19 in equipment family, with a specific focus on connector dependent interface dimensions. In practical terms, it helps engineers and compliance teams align enclosure design, module layout, and connector positioning during technical review and verification activities. It is commonly used as a dimensional basis when assessing whether equipment interfaces are suitable for integration, procurement, or documented evaluation.

Applications of IEC 60297-3-104:2006

IEC 60297-3-104:2006 is typically applied in rack-based electronic equipment programs where standardized mechanical fit is important, such as control systems, instrumentation platforms, and modular industrial electronics. It may also support laboratory evaluation, prototype validation, and procurement review when comparing subrack or plug-in unit designs from different suppliers. For organizations managing engineering specifications, it provides a useful reference for checking interface compatibility before manufacturing, assembly, or conformity assessment preparation.

Why is IEC 60297-3-104:2006 important?

This technical document helps reduce integration risk by giving a common dimensional basis for connector-related interfaces in 19 in subracks and plug-in units. That matters for safety, interoperability, and quality workflows because mechanical mismatch can lead to installation issues, rework, or failed verification testing. For procurement and compliance teams, IEC 60297-3-104:2006 supports clearer technical validation, more consistent supplier evaluation, and better preparation for documented compliance and conformity assessment.
