SIST EN 61169-35:2011/oprA1:2026

SIST EN 61169-35:2011/oprA1:2026 is Amendment 1 to the sectional specification for 2,92 series RF connectors. It updates the connector ratings and characteristics used to define, test and compare these radio-frequency connectors, including the addition of Grade 0 connectors. Engineers, quality teams and buyers use it to match connector grade, style and test method to the intended RF application.

What does SIST EN 61169-35:2011/oprA1:2026 specify?

SIST EN 61169-35:2011/oprA1:2026 specifies an amendment to the 2,92 series RF connector sectional specification. Its main purpose is to revise the performance table for these connectors and to add Grade 0 connectors for higher-frequency use.

The document is organized around a short purpose statement, a replacement for Table 6, and a technical rationale that explains why the frequency coverage is being extended. The revised table brings together electrical, mechanical, environmental and endurance ratings in one place so users can check suitability against a required application.

What are the key requirements of SIST EN 61169-35:2011/oprA1:2026?

SIST EN 61169-35:2011/oprA1:2026 updates the key rating table for 2,92 series RF connectors and ties each rating to a test method from IEC 61169-1. In practice, the document is mainly a qualification and selection reference: it tells you what performance has to be demonstrated and which connector variants need a separate check.

Electrical performance

• Table 6 sets the nominal impedance and separates the connector grades by frequency range, including the newly added Grade 0 connectors. In practice, the grade must match the operating band of the system, especially where higher-frequency measurement coverage is needed.
• The table gives reflection factor limits under subclause 9.2.1 and distinguishes straight styles from right-angle, component mounting, solder bucket and PCB mounting styles. This matters because not every mechanical style has the same RF performance, so the detail specification has to be checked for the exact variant.
• The electrical checks also cover centre contact resistance, outer conductor continuity and insulation resistance before and after conditioning. This means users have to verify that electrical contact quality stays acceptable after environmental stress.

Withstand voltage, screening and mechanical integrity

• Table 6 includes proof voltage and environmental test voltage requirements, with separate values for sea level and low-pressure conditions and different cable constructions. In practice, altitude and cable type affect the test plan and the acceptable assembly.
• Screening effectiveness is specified for straight cables only, and only when the interfaces are fully mated. That tells users that shielding performance is an assembly property, not just a connector body property.
• Mechanical checks cover gauge retention, centre contact captivation, engagement and separation, coupling torque, tensile strength of the coupling mechanism, vibration and shock. These tests matter because they show whether the connector can be assembled, mated and handled without loosening or damage.

Environmental and endurance performance

• The table includes climatic categories, sealing requirements for non-hermetic and hermetic versions, salt mist exposure, mechanical endurance and high-temperature endurance. In practice, these ratings help users decide whether the connector is suitable for the intended operating environment and service life.
• Several notes in the table say that ratings can depend on the cable used and that some limits are governed by the cable specification. This means the connector cannot be selected in isolation - the cable assembly has to be considered with it.

What terms does SIST EN 61169-35:2011/oprA1:2026 define?

• Grade 0 connectors - the connector grade added by this amendment for the extended frequency use case.
• Grade 1 connectors - the existing connector grade retained in the rating table.
• detail specification (DS) - the product-specific document to consult when the table says "See DS" for a particular style or condition.
• Climatic category - the code used to describe the temperature and humidity service profile for qualification.
• Hermetic - a sealing condition intended for gas-tight performance with a tighter leakage limit.
• Non-hermetic - a sealing condition with a looser leakage limit than hermetic sealing.
• Reflection factor - the RF measure used here to express how well the connector matches the line and limits reflected energy.

Who uses SIST EN 61169-35:2011/oprA1:2026?

SIST EN 61169-35:2011/oprA1:2026 is used by connector designers, cable assembly manufacturers, test laboratories, quality teams and procurement staff. It is especially relevant in RF and microwave work where 2,92 series connectors are used for qualification, incoming inspection, product definition and supplier comparison.

It also matters to users working on high-frequency measurement and 5G-related applications, because the amendment rationale links the added Grade 0 connector to wider frequency coverage.

What changed in SIST EN 61169-35:2011/oprA1:2026 from the previous edition?

SIST EN 61169-35:2011/oprA1:2026 is Amendment 1 to IEC 61169-35:2011. The change note states that it adds Grade 0 connectors, updates the title and introductory text, and replaces Table 6. The rationale explains that the amendment extends the connector’s frequency coverage for the 5G use case discussed in the document.

Which standards are used with SIST EN 61169-35:2011/oprA1:2026?

IEC 61169-1 is the companion standard named in the table, and it provides the standard test methods used for the electrical, mechanical and environmental checks. SIST EN 61169-35:2011/oprA1:2026 builds on IEC 61169-35:2011, which it amends.

What does the SIST EN 61169-35:2011/oprA1:2026 document contain?

SIST EN 61169-35:2011/oprA1:2026 contains the amendment notice, the purpose statement, the revised Table 6 and a short technical justification for the change. The table brings together the connector ratings and characteristics used for design review, qualification and product verification.

It also includes notes that explain how cable type, connector style and mating condition affect the stated performance. These notes are important because they tell the reader when a rating applies to the connector alone and when it depends on the complete assembly.
