XLR-3 Cable - 25ft
This is a 25 foot (~7.6m) long XLR-3 cable capable of better communications for lighting and special effects through standard or digital communication protocols. We specifically like to use this cable with our ESP32 Thing Plus DMX to LED Shield but it can also be used with DMX fixtures that utilize an XLR-3 jack.
This cable possesses a 24AWG diameter and is terminated with a 3-pin male XLR connector at one end and a 3-pin female XLR connector at the other.
Note: The usage of 3-pin XLR connectors for DMX signals is technically prohibited by section 7 of ANSI E1.11 - 2008. Please take care not to confuse lighting cables with audio cables.

As I posted on the interface board, DMX explicitly disallows 3-pin XLR - see section 7.1.2. It must be 5-pin XLR to be DMX. The only other connector allowed is RJ-45 for fixed or permanent installs. For more, see https://en.wikipedia.org/wiki/DMX512#Connectors. You should remove the term 'DMX' from this product to eliminate confusion.
It's still compatible with DMX512, therefore it would be false advertising to NOT state that it's DMX. Even if it's expressly disallowed by the spec, people are still doing it for the "budget" range of lighting equipment; ergo, it is a de facto DMX cable, compatible with devices supporting 3-pin DMX connectivity. Any device using 3-pin XLR for its DMX512 communication is compatible, so it is a DMX device.
Just because some cheap gear has 3-pin XLR on it isn't an excuse to trample on very explicit standards. It is currently false advertising to label these products as DMX. USITT and ANSI have been VERY clear on this over the years, and have a very firm stance on this. You could label this cable as capable of carrying a RS-485 signal if its impedance is 120 ohms (they don't even list that, this could be mic cable for anyone ordering this cable knows), you cannot say this is a DMX cable as by its connectors (and unlisted complying impedance rating), it is NOT. Saying that any device using 3-pin XLR for RS-485 signals is DMX is patently false and misleading.
