Full title and description

Connectors for electronic equipment - Product requirements - Part 2-106: Circular connectors - Detail specification for connectors M16 x 0,75 with screw‑locking and degree of protection IP40 or IP65/67. This International Standard specifies mechanical, electrical and environmental requirements for fixed and free circular M16 × 0,75 screw‑locking connectors (rewireable and non‑rewireable) with male round contacts (ø 1,5 mm or ø 1,0 mm), intended primarily for industrial process measurement and control applications.

Abstract

This standard defines the detail specification for M16 × 0,75 circular connectors with screw locking and specified degrees of protection (IP40 and IP65/67). It covers connector types, contact arrangements/sizes, electrical and mechanical performance requirements, environmental and sealing requirements, marking and verification tests to ensure reliable mating, interchangeability and suitability for use in industrial instrumentation and control systems.

Scope

IEC 61076‑2‑106:2011 specifies the detail requirements for circular connectors with M16 × 0,75 screw‑locking, available as fixed and free connectors and as rewireable or non‑rewireable versions. The standard addresses two protection classes (IP40 and IP65/67), contact diameters (≈1,5 mm and ≈1,0 mm for male contacts), mating interfaces, mechanical dimensions, materials, marking and the suite of electrical, mechanical and environmental tests needed to verify conformity for industrial process measurement and control applications. The standard also notes potential mating interface relationships with certain connector styles in IEC 60130‑9 and provides guidance on compatibility considerations.

Key topics and requirements

• Mechanical specifications: M16 × 0,75 screw‑locking geometry, dimensional tolerances and mating arrangements.
• Contact details: permitted contact diameters (male contacts ø 1,5 mm or ø 1,0 mm) and contact arrangements.
• Degrees of protection: requirements and tests for IP40 and IP65/67 sealing performance.
• Electrical requirements: insulation resistance, dielectric strength and current/voltage ratings as applicable to the contact sizes and intended use.
• Mechanical performance: mating/unmating cycles, retention, vibration and mechanical shock tests.
• Environmental and ageing tests: temperature, humidity, salt spray and other relevant environmental verifications.
• Materials, plating and corrosion resistance, plus marking and identification requirements.
• Assembly, rewireable vs non‑rewireable construction and verification/test procedures for conformity.

Typical use and users

Typical applications are industrial process measurement, sensors, actuators, field instrumentation and control equipment where compact, robust circular connectors with IP40 or IP65/67 protection are required. Primary users include connector and equipment manufacturers, product designers, system integrators, test laboratories, procurement/specification engineers and certification bodies working in industrial automation and instrumentation.

Related standards

IEC 61076‑2‑106 is one part of the IEC 61076 connector series (product requirements for various connector families) and is developed under the IEC technical committee for electrical connectors (TC 48 / SC 48B). Users commonly refer to related documents for complementary requirements and tests, such as IEC 60529 (degrees of protection — IP codes) and IEC 60130‑9 for historical mating interface comparisons noted in national guidance. National/adopted versions (EN/BS/DIN/etc.) exist and may include editorial or language adaptations.
