5.12.9. Classify Electrical Parts

	Note
This chapter's focus is on using the CNS classification. That target systems additionally need to be classified according to eClass in order to identify the part type, remains untouched by this. Within the CNS classification, in addition to the labeling with specific electrical classes (CNSELEK [component level] or CNS_CP\|4 [connection points]), the labeling with classes for determining the graphical representation (CNSCAX\|GFX) or material characteristic properties (CNSERPBASE [see Section 5.12.3.1, “Classification (CNS) ”]) is also important, to name just a few.

Within the CNS classification, in addition to the labeling with specific electrical classes (CNSELEK [component level] or CNS_CP|4 [connection points]), the labeling with classes for determining the graphical representation (CNSCAX|GFX) or material characteristic properties (CNSERPBASE [see Section 5.12.3.1, “Classification (CNS) ”]) is also important, to name just a few.

In the field of electrical engineering not only the outer shape of a component is decisive: In fact, engineers need further information, especially connection information, when looking for an appropriate part. In order for electrical components to be properly exported in respective ECAD target systems, they have to be classified accordingly.

Some classes refer to the component as a whole, others to specific areas such as electrical connections or plug connections. When classifying, this is reflected in the choice of filter such as classes [Classes] or connection points [Connection points].

Filter classes
Part classifications such as article number, descriptions and IEC code 81346_2, for example (see Section 5.12.9.3, “Classification according to IEC Code 81346_2”)

Filter connection points

Note

Appropriately positioned connection points must already exist.

A connection point can fulfill different tasks, that's why classification for electrical CADs (ECADs) is decisively.

^[a]Electrical Connection (CNS_CP|4|3)
On this see Section 5.12.9.4, “Classification of Electrical Connections [CNS_CP|4|3])”.
Mounting Points (CNS_CP|4|6)
Drillings (CNS_CP|4|2)
Elektro Alignment Coordsys (CNS_CP|4|5)
On this see Section 5.12.9.1.1, “ Set connection point ”.

Depending on class, very different values have to be entered for the specification of points. So it makes a big difference, if a borehole diameter or a stripping length is specified, for example.

Feature CNS_CP|4|2::000008001 applies to the drill hole diameter, while CNS_CP|4|3::000036001applies to the stripping length.

General rules for classifying can hardly be found, because each supplier prefers different definitions, for example for the position of electrical connections. Furthermore the position of electrical connections may depend on whether a stripped wire shall be plugged in or a hard metallic connector (male) [compare shockproof plug]. In the case of the below depicted terminal, which complies with the first case, the electrical connections are near the bottom.

^[a]Classes meant for connection level (and not for the whole part) can be recognized by the prefix "CNS_CP".

The prerequisite for classification is a current CNS classification.

If necessary, update the CNS classification via PARTadmin -> Catalog update -> Online.
