IEC 63171-2:2021 pdf download.Connectors for electrical and electronic equipment – Part 2: Detail specification for 2-way, shielded or unshielded
1 Scope
This part of IEC 63171 covers 2-way, shielded or unshielded, free and fixed connectors for data transmission up to 600 MHz, with current-carrying capacity, known as Type 2. It specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications respectively. The form factor of these connectors allows their use for cable sharing with already installed TO’s for structured cabling. NOTE The overall performance of the transmission channel in such case has to be evaluated. Intermateable and interoperable versions for circular connector for sealed applications including this connector are described in IEC 63171-5. The shielded and unshielded connectors are interoperable for their internal transmission performance and can be exchanged. The shielded version has improved alien crosstalk and coupling attenuation properties.

4 Common features and typical connector pair
4.1 Mating information 4.1.1 General Dimensions are given in millimetres. Drawings are shown in first angle projection. The shape of connectors may deviate from those given in Figure 2 to Figure 5, as long as the dimensions specified are not changed, see also Table 1 and Table 2. NOTE When using the snap-in version of the free connector, the mating face of the free connector can also be used as mating face of a fixed connector and the mating face of the fixed connector can be used as mating face of a free connector.
5.3 Classification into climatic category The temperature range and climatic category shall be compatible with ISO/IEC 11801-1 classification of a M1I1C1E1 environment. 5.4 Electrical characteristics 5.4.1 Creepage and clearance distances The permissible operating voltages depend on the application and on the specified safety requirements. Although insulation coordination is not required for safety aspects for these connectors, it is still required for their electrical functional requirements. In general, for minimum values of clearances and creepage distances IEC 60664-1 shall apply, based on the assigned voltage rating 50 VAC and 60 V DC. NOTE As indicated in IEC 60664-1, IEC TR 63040 provides an alternative and more precise dimensioning procedure for clearances equal to or less than 2 mm. The creepage and clearance distances that cover performance requirements in IEC 60664-1 may be reduced, based on IEC TR 63040. The creepage and clearance distances given in Table 3 apply as operating characteristics for mated connectors according to this document. In practice, reductions in creepage or clearance distances may occur due to the conductive pattern of the printed board or the wiring used and should duly be taken into account.
