IEC 61076-3-115:2009

Overview

IEC 61076-3-115:2009 is an international standard published by the International Electrotechnical Commission (IEC) that specifies product requirements for protective housings used with 8-way rectangular shielded and unshielded connectors. These connectors operate at frequencies up to 600 MHz and are designed specifically for industrial environments. This standard incorporates the interface specifications from the IEC 60603-7 series and focuses on Variant 12, related to IEC 61076-3-106, which uses a push-pull coupling type.

The main objective of IEC 61076-3-115 is to enhance existing 8-way connector systems by providing detailed specifications for protective housings that upgrade connectors to meet IP65 and IP67 ingress protection ratings as defined in IEC 60529. This makes these connectors highly suitable for use in harsh industrial environments where resistance to dust and water ingress is critical.

Key Topics

• Scope and Object: Protective housings compatible with 8-way shielded/unshielded connectors for frequencies up to 600 MHz, designed for industrial settings.

• Interface Compatibility: Incorporates IEC 60603-7 series interface standards (parts 2, 3, 4, 5, 7), with emphasis on Variant 12 push-pull coupling related to IEC 61076-3-106.

• Ingress Protection: Defines housings upgrading connectors to IP65 and IP67 protection classes for reliable sealing against dust and water.

• Connector Types:

  • Fixed connectors
  • Free (receptacle) connectors
  • Various locking mechanisms and mounting configurations

• Mechanical and Electrical Characteristics: Coverage of climatic category, clearance and creepage distances, voltage proof, current derating, mating cycles, and insulation resistance specific to industrial conditions.

• Testing Procedures: Comprehensive test schedules including mechanical, climatic, electrical, and transmission characteristic evaluations to ensure compliance and durability in industrial applications.

• Mounting and Termination: Detailed mounting information, caps for fixed and free connectors, and termination methods specified per IEC 60603-7.

• Push-pull Coupling: Variant 12 push-pull type enables efficient, secure, and quick connection/disconnection, improving operational efficiency in industrial electronic equipment.

Applications
