IEC 63171-2:2021 pdf download – Connectors for electrical and electronic equipment – Part 2: Detail specification for 2-way, shielded or unshielded, free and fixed connectors: mechanical mating information, pin assignment and additional requirements for type 2

IEC 63171-2:2021 pertains to two-way connectors, both shielded and unshielded, that can be used for free or fixed applications and are capable of data transmission at frequencies up to 600 MHz, classified as Type 2 due to their current-carrying capacity. The standard specifies the essential dimensions, as well as mechanical, electrical, and transmission characteristics, in addition to environmental requirements and relevant testing protocols.

These connectors are designed to facilitate cable sharing with existing TOs in structured cabling environments.

It is essential to evaluate the overall performance of the transmission channel in these configurations.

Versions of circular connectors for sealed applications, including the ones discussed, are also detailed in IEC 63171-5, ensuring they are interchangeable and compatible.

Both shielded and unshielded connectors maintain compatibility in their internal transmission capabilities and can be swapped without issue. The shielded variant provides improved performance in terms of alien crosstalk and coupling attenuation.
