IEC 61076-3-100:1999

Overview

IEC 61076-3-100:1999 is an international standard developed by the International Electrotechnical Commission (IEC) for rectangular connectors used in d.c., low-frequency analogue, and digital high speed data applications. This standard specifies a range of shielded two-part connectors featuring trapezoidal-shaped shells and non-removable ribbon contacts, arranged in a 1,27 mm double row. These connectors are designed with reliability and assessed quality in mind, making them suitable for a wide range of electronic applications where signal integrity and robust mechanical performance are essential.

The standard applies to both fixed and free connectors:

• Fixed connectors: Mounted vertically or at a right angle to printed circuit boards or panels, with options for dip solder or insulation displacement terminations.
• Free connectors: Attached to cables with non-accessible insulation displacement terminations, accommodating conductor counts from 14 up to 110.

By adhering to IEC 61076-3-100:1999, manufacturers and users ensure compatibility, consistent performance, and international interoperability for shielded trapezoidal connectors in modern electronic systems.

Key Topics

• Assessed Quality: The standard defines quality management and assessment procedures, ensuring consistent product reliability across different suppliers and use cases.
• Connector Variants: Covers shielded connectors with options for right-angle, vertical mounting, locking latches, and screw-locking mechanisms.
• Contact Arrangements: Specifies 1,27 mm pitch double rows for mating interfaces and 2,54 mm × 1,905 mm for board terminations, supporting 14 to 110 contacts.
• Rated Performance:
  • Working voltage: up to 250 V a.c.
  • Current rating: up to 1 A, depending on contact size.
  • Minimum insulation resistance: 500 MΩ.
• Mechanical Protection: The trapezoidal shell shape prevents mismating, while shielded construction aids in electromagnetic compatibility (EMC).
• Mounting Information: Guidance on mounting methods, board thickness compatibility (0,8 mm to 2,4 mm), and termination types.

Applications

Connectors conforming to IEC 61076-3-100:1999 are used in a wide spectrum of electronic assemblies that require both signal integrity and mechanical robustness. Typical applications include:

• Industrial Automation: Reliable interconnection for control systems, sensors, and fieldbus devices.
• Data Communication Equipment: Used in devices requiring high speed data transfer and low-frequency analog signals with EMC protection.
• Computing Hardware: Suitable for internal and external connections in servers, storage units, and modular electronic systems.
• Test and Measurement Equipment: Ensures secure connections for precise analog and digital signal transmission.
• Consumer Electronics: Embedded in products that demand compact, shielded, and high-density connectors.
