Part Number Canvas

Checking a designed part number by drawing it

Five items: family, sensing method and generation, ingress rating, connection and revision. The part number built in the design guide, drawn as it stands.

How to read the part number

The fictional part number TS-A2-W67-M12-R1 is split into 5 items.

In the part numberItemOptions
TS Family
TS = Temperature sensor (fictional)
A2 Sensing method and generation
A1 = RTD, 1st generation
A2 = RTD, 2nd generation
W67 Ingress rating
W54 = IP54
W67 = IP67
M12 Connection
M8 = M8 connector
M12 = M12 connector
CB = Flying lead
R1 Revision
R1 = First release

Notes

  • The revision goes up with every compatible change. Mounting dimensions and wiring stay the same across revisions.

What went into this one

Two facts in two characters

Sensing method and generation share one range: the letter is the method, the digit the generation. Drawn, the heading needs an “and”, which makes the two facts in one range visible. Split it into two one-character items if you would rather keep them apart.

Options of different lengths

The connection options are M8, M12 and CB — two characters and three. The diagram underlines the range in the part number and lists every option under the heading, so options of uneven length can still be drawn. A reader hesitates for a moment, though; if one width can be settled while designing, settle it.

Revision last, its meaning in a note

The revision mark sits at the end, and only R1 is listed because only R1 exists. What makes the revision go up does not fit in an option's description, so it is a note under the diagram.
