IEC 63171-2 pdf – 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

This part of lEC 63171 covers 2-way, shielded or unshielded, free and fixed connectors for datatransmission up to 600 MHz,with current-carrying capacity, known as Type 2. It specifies thecommon dimensions, mechanical, electrical and transmission characteristics and environmentalrequirements as well as test specifications respectively.
The form factor of these connectors allows their use for cable sharing with already installedTOs 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 includingthis connector are described in lEC 63171-5.
The shielded and unshielded connectors are interoperable for their internal transmissionperformance and can be exchanged. The shielded version has improved alien crosstalk andcoupling attenuation properties.

4Common features and typical connector pair
4.1Mating information
4.1.1General
Dimensions are given in millimetres. Drawings are shown in first angle projection. The shapeof 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 usedas mating face of a fixed connector and the mating face of the fixed coninector can be used as mating face of a freeconnector.
5 Characteristics
5.1 General
Compliance to the test schedules is intended to ensure the reliability of all performance parameters, including transmission parameters, over the range of operating climatic conditions.
5.2 Pin assignment
For those specifications where pin assignment is relevant the pin assignment shall be as shown in Figure 6, unless otherwise specified.
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.
ln general, for minimum values of clearances and creepage distances IEC 60664-1 shall apply.based on the assigned voltage rating 50 VAC and 6o v Dc.
NOTE As indicated in IEC 60664-1, IEC TR 63040 provides an alternative and more precise dimensioningprocedure for clearances equal to or less than 2 mm.
The creepage and clearance distances that cover performance requirements in lEC 60664-1may be reduced, based on lEC TR63040.
The creepage and clearance distances given in Table 3 apply as operating characteristics formated connectors according to this document.
In practice，reductions in creepage or clearance distances may occur due to the conductivepattern of the printed board or the wiring used and should duly be taken into account.
