IEC 61076-3-119:2017

Overview

IEC 61076-3-119:2017 is an IEC detail specification for rectangular connectors targeted at industrial data transmission up to 100 MHz. It defines product requirements, dimensions, electrical and mechanical performance and test methods for shielded and unshielded, free and fixed 10‑way connectors with a push‑pull coupling. The standard covers connectors with round contacts designed for screw or crimp terminations (other termination methods allowed by agreement). Push‑pull locking supports IP65/IP67 protection per IEC 60529. These connectors are specified without breaking capacity (COC per IEC 61984:2008) and therefore are not intended to be mated or unmated under load or live conditions unless the manufacturer specifies otherwise.

Key Topics and Technical Requirements

• Connector types: Free (female) and fixed (male) 10‑way rectangular connectors, shielded and unshielded.
• Contacts & terminations: Round contacts suitable for screw or crimp; alternative termination techniques by agreement.
• Electrical ratings & tests: Requirements for rated current/voltage, insulation resistance, voltage‑proof testing and transmission parameters for frequencies up to 100 MHz.
• Signal performance: Transmission characteristics including insertion loss, return loss, NEXT, FEXT and transfer impedance for shield performance.
• Mechanical requirements: Push‑pull coupling effectiveness, insertion/withdrawal forces, contact retention, polarization/coding and mounting details (panel cut‑outs, gauges).
• Environmental & reliability: Climatic categories, vibration and shock tests, IP protection (IP65/IP67), and material/marking provisions.
• Test schedules: Basic and full test schedules, specimen wiring and conditioning, plus specific measurement arrangements for contact and shield resistance.
• Safety note: Connectors are specified without breaking capacity - do not engage/disengage live unless explicitly permitted by the manufacturer.

Applications and Who Uses This Standard

IEC 61076-3-119 is relevant for:

• Connector manufacturers designing and certifying compact industrial rectangular connectors (10‑way) with push‑pull coupling.
• OEMs and system integrators specifying reliable industrial data interfaces for automation, control, sensors, robotics and fieldbus applications operating ≤100 MHz.
• Procurement and quality engineers verifying component compliance, IP protection and mechanical endurance.
• Test laboratories performing electrical, mechanical and environmental validation per the standard’s test schedules.

Practical benefits include reliable mating under industrial conditions, predictable electromagnetic performance (shielding), and standardized mechanical interfaces for panel and cable assemblies.
