EN 61169-32:1999

Overview

EN 61169-32:1999 (published by CLC) is the European adoption of IEC 61169‑32 and defines the requirements for RF coaxial connectors with an inner diameter of outer conductor 1.85 mm (type 1.85). These 50 ohm, screw‑coupling connectors are specified for use with semi‑rigid and flexible coaxial cables and intended for microwave applications up to 65 GHz. The standard provides the normative basis for compatibility, performance and interchangeability of the type 1.85 family in high‑frequency systems.

Key Topics

• Mechanical dimensions and mating - required interface geometry for a 1.85 mm outer conductor inner diameter and screw coupling to ensure mechanical compatibility.
• Characteristic impedance - confirmation of 50 ohm electrical interface intended for controlled impedance systems.
• Frequency performance - suitability and test considerations for operation up to 65 GHz (microwave band).
• Cable compatibility - guidance for use with semi‑rigid and flexible cable types commonly used in high‑frequency assemblies.
• Mechanical and electrical tests - standardized test procedures for verifying connector performance (mating durability, electrical continuity, and RF performance).
• Material and plating considerations - general expectations for materials and finishes to meet electrical and mechanical requirements (without prescribing specific proprietary materials).
• Marking and identification - requirements for labeling and traceability to support procurement and maintenance.

Applications

EN 61169‑32:1999 (type 1.85) is aimed at sectors requiring compact, high‑performance RF connections, including:

• Microwave and millimeter‑wave test systems and measurement fixtures
• Laboratory and R&D equipment for antennas, amplifiers and transceivers
• Aerospace, defense and satellite subsystems where compact 50 Ω interfaces are needed
• High‑frequency instrumentation and calibration devices
• Manufacturers of semi‑rigid/flexible cable assemblies and RF interconnect components

Typical users:

• Connector and cable manufacturers
• RF/microwave system designers and test engineers
• Procurement and quality teams ensuring component interchangeability
• Test laboratories conducting high‑frequency measurements

Related Standards

• IEC/EN 61169 family (other parts cover different RF connector types and sizes)
• National adoptions and translations (EN versions adopt IEC content; check local CLC publications for nation‑specific notices)

EN 61169‑32:1999 is essential when specifying compact, 1.85 mm RF coaxial connectors (type 1.85) for reliable 50 Ω performance up to 65 GHz-helping ensure mechanical interchangeability and predictable RF behavior across devices and vendors.
