IEC 61169-17:2022

Overview

IEC 61169-17:2022 is an international standard published by the International Electrotechnical Commission (IEC) that specifies sectional requirements for RF coaxial connectors-specifically the series TNC type with 50-ohm characteristic impedance and an inner diameter of 6.5 mm for the outer conductor. These connectors feature screw coupling and are widely used in microwave transmission systems operating up to 11 GHz.

This standard provides critical guidelines for preparing detailed specifications (DS) for TNC connectors, including precise mating face dimensions for high-performance grade 2 connectors, dimensional details for grade 0 standard test connectors, gauging information, and testing procedures based on IEC 61169-1. IEC 61169-17:2022 also outlines recommended performance characteristics and test schedules for quality assessments according to assessment levels M and H.

Key Topics

• Scope and Purpose
  Defines the framework for detail specifications related to series TNC RF coaxial connectors with a characteristic impedance of 50 Ω and screw coupling, facilitating consistency and interoperability across designs and manufacturers.

• Mating Face Dimensions
  Establishes standardized dimensions for the connector's mating face-critical for ensuring robust mechanical and electrical connections. Details are specified for connectors with pin and socket center contacts, identifying high-performance (grade 2) and test (grade 0) variants.

• Gauging and Quality Control
  Includes specifications for gauges used to verify connector dimensions, ensuring conformance and interchangeability. Gauges for the pin center contact, socket center contact, and outer conductor are clearly defined.

• Testing and Performance Requirements
  Summarizes performance ratings and characteristics to be considered when designing or specifying connectors. It also lists acceptance and periodic tests for durability, environmental resistance, electrical performance, and mechanical reliability drawn from IEC 61169-1 standards.

• Preparation of Detail Specifications (DS)
  Offers detailed instructions and a blank pro-forma for writing DS documents, covering identification, performance parameters, marking, ordering information, and applicable test procedures.

• Assessment Levels
  Test schedules and inspection requirements are provided for assessment levels M (medium) and H (high), allowing for tailored quality assurance depending on end-use applications.
