Full title and description

Connectors for electronic equipment - Product requirements - Part 2-105: Circular connectors - Detail specification for M5 connectors with screw-locking. This part specifies dimensional, mechanical and electrical product requirements for M5 circular connectors with screw-locking, typically used for industrial process measurement and control applications.

Abstract

IEC 61076-2-105:2008 defines the detail specification for M5 circular connectors with screw-locking. It covers connector types (fixed and free), contact arrangements and sizes, mechanical construction and mating, electrical performance and environmental/test requirements appropriate for sensors, actuators and other field devices in industrial process-control environments.

Scope

Specifies product requirements for circular M5 connectors with screw-locking intended for industrial process measurement and control. The standard covers fixed (non‑rewireable or rewireable) and free (non‑rewireable) connectors, contact sizes and arrangements, mechanical characteristics (mating, retention and locking), electrical performance, and applicable tests to verify mechanical, electrical and environmental performance.

Key topics and requirements

• Detail specification for M5 circular connectors with screw-locking (dimensional and mechanical requirements).
• Types covered: fixed (non‑rewireable or rewireable) and free (non‑rewireable) connectors.
• Contact design and nominal contact diameter for male contacts (noted in national adoptions as ∅ 0.48 mm for male contacts).
• Electrical requirements (current/voltage ratings, contact resistance limits) and mechanical performance (mating cycles, retention force, torque for screw‑locking).
• Environmental and reliability tests referenced to generic connector test standards (for example IEC 61076‑1 and IEC/EN test methods such as IEC 60512 series).
• Application guidance for use in process instrumentation and automation (sensors, actuators, field devices).

Typical use and users

Used by connector and device manufacturers, product designers, test laboratories, procurement/specification engineers and system integrators in industrial automation, process control, instrumentation and sensor markets. Typical applications include sensor/actuator cabling, small‑signal instrumentation and field I/O where compact screw‑locking M5 connections are required.
