AWM 21894, PVC Jacketed Multi-Conductor Appliance Wiring Material, Sunlight and Oil Resistant

UL AWM Style 21894 looks like 2103 on the drawing and behaves differently in service. Same multi-conductor build, same 105°C and 300 Vac, same extruded PVC jacket, but the jacket wall starts at 30 mils instead of 15, the compound is required to be oil resistant to 60°C and sunlight resistant, and the style is listed for external wiring rather than internal. That combination is what makes it useful on a machine that sits outdoors or in a wash-down area: the cable can be run exposed, in sun, against oil mist, without a conduit or an extra sleeve. Jacket thickness runs from 30 mils minimum average up to 80 mils on a 38 to 63 mm cable, with minimum at any point at 80 percent of those figures. If the run stays inside the cabinet, 2103 does the same job on a thinner jacket for less money; if it goes outside, 21894 is the one that carries the markings.
