The 3239-xx cables from CNC Tech are available in several different lengths, however the manufacturer part number’s length spec of 500ft is static, for example if you want a 1,000ft spool that is not offered at this time, and attempting to order “3239-18-1-1000-004-1-TS” will not get you anywhere. That section of the part number does call out length, but it is not customizable unless you contact the manufacturer directly and negotiate a custom spool with them. There are some options available in a 100ft length from the manufacturer, but the majority arrive on 500ft spools and are cut down as needed at DigiKey.
As for the numbering system , the first “XX” in 3239-XX-1-0500-0XX-1-TS is used to call out wire gauge (Ranging from 10-24AWG) and the “0XX” calls out jacket color, as shown page 2 of the following datasheet: https://www.cnctech.us/pdfs/3239-XX-1-0500-0XX-1-TS.pdf
