Description (English):

IEC 63171-6:2021 covers 2-way and 4-way (data/power), shielded, free and fixed connectors for data transmission with frequencies up to 600 MHz and specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications. This second edition cancels and replaces the first edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Mating conditions changed, see Figure 2, Figure 4, Figure 13, Figure 15, Figure 19 and Figure 21. b) Voltage proof requirement added, 2 250 V DC, see 5.7.2. c) Mechanical shock requirement added, see 5.7.6 (the requirement itself already was specified indirectly by Ed1 due to the specification of the test EP3 of Table 14 which is still identical to Ed1). d) Styles added, 6P-M8CI and 6J-M8CI, see Table 1.

Abstract

Overview

IEC 63171-6:2021 is an International Electrotechnical Commission (IEC) standard that defines detailed specifications for shielded 2-way and 4-way data/power connectors (free and fixed) intended for combined power and data transmission at frequencies up to 600 MHz. The second edition (2021) updates mating conditions, adds a voltage proof requirement (2 250 V DC), introduces a mechanical shock requirement and two new styles (6P‑M8CI and 6J‑M8CI). The standard specifies common dimensions, mechanical and electrical characteristics, transmission requirements, environmental ratings and test procedures.

Key topics and requirements

Connector types and styles: Defines multiple mechanical styles including M8 and M12 variants and specific 2‑way and 4‑way configurations; includes overall and mating dimensions and pin assignments.
Electrical characteristics: Requirements for voltage rating, voltage proof (2 250 V DC), current‑carrying capacity, contact and shield resistance, insulation resistance, and impedance.
Transmission performance: Specifications and test methods for insertion loss, return loss, propagation delay, transfer impedance, coupling attenuation, and alien NEXT/FEXT metrics up to 600 MHz.
Mechanical requirements: Insertion/withdrawal forces, polarization, vibration and mechanical shock resistance (new explicit shock requirement), mating conditions, and durability (number of mating cycles).
Environmental and safety: Climatic category classification, IP degree of protection, clearance and creepage distances and derating diagrams for data and power pins.
Test specifications: Detailed test schedules and groups (basic and full test schedules), mounting arrangements for specimens, and standardized test procedures for electrical, mechanical and environmental verification.

Applications and users

IEC 63171-6 is intended for:

Connector manufacturers designing shielded data/power 2‑way and 4‑way solutions (M8/M12 and other styles).
OEMs and equipment designers building industrial automation, robotics, sensors, fieldbus and PoDL/PoE-like systems that require combined power and data over compact connectors.
Test laboratories and compliance engineers performing type and routine testing to IEC requirements (electrical, mechanical, environmental and RF transmission).
System integrators and procurement teams evaluating connector compatibility, performance up to 600 MHz, and environmental suitability.

Practical benefits include consistent mechanical interoperability, verified signal integrity (insertion/return loss and crosstalk controls), robust power delivery, and harmonized test methods for reliable, field‑grade connector selection.

Other parts of the IEC 63171 series cover alternative connector variants and higher‑level system considerations. Users should consult the complete IEC catalogue for related connector and electrotechnical standards.
