IEC 61076-4-103:1999

IEC 61076-4-103:1999 defines requirements for connectors used in d.c. low-frequency analogue and digital high speed data applications, with a focus on printed board connectors with assessed quality. It covers a detail specification for two-part connectors with shielding and a basic grid of 2,5 mm, making it relevant for engineers and procurement teams that need a technical document for component selection, verification activities, and conformity assessment. For organizations working with connector qualification, the reference supports more consistent technical review and compliance workflows.

What is IEC 61076-4-103:1999?

IEC 61076-4-103:1999 is a detail specification within the IEC 61076 connector series, addressing printed board connectors for analogue and high speed digital data applications. Its title indicates a two-part connector arrangement with shielding and a 2,5 mm basic grid, which suggests a focus on connector interface definition, assessed quality, and product evaluation against a structured technical reference. In practice, it is useful when documenting connector requirements, supporting laboratory evaluation, and aligning engineering documentation with a defined compliance reference.

Applications of IEC 61076-4-103:1999

This document is typically relevant in electronic equipment design, printed circuit board interconnection, and assemblies where shielded connectors are used to support reliable signal transmission. It may be consulted during design validation, supplier qualification, and testing workflows for analogue or digital data interfaces in industrial control, instrumentation, communications hardware, and other electrical equipment. Teams involved in procurement review or conformity assessment can use it as a technical basis for comparing connector parts and confirming that the selected interface matches the intended application.

Why is IEC 61076-4-103:1999 important?

The value of IEC 61076-4-103:1999 lies in its role as a consistent engineering specification for connector selection and assessment. By defining a detailed connector type with shielding and a specified grid, it helps reduce ambiguity during technical validation and supports operational consistency across design, sourcing, and inspection activities. That can improve quality assurance, lower integration risk, and make regulatory preparation and conformity assessment more straightforward, especially where repeatable connector performance is important to system reliability.
