PART NUMBERS Tag Description
The CNC Part Number is on a metal tag or paper label. The tag varies in size from ½ to 1 inch wide and 1 to 5 inches long. The label tag has three pieces of important information: Part Number (Control Type), Serial No and Date of Manufacture. The part number is the top-level number and help's identify the control type. The “Date” is the manufacture date of the product. The Fanuc Part number is made up of three blocks of four digits normally starting with an A (eg A06B-6058-H223).

The Fanuc Series 0A, 0B, 0C, 0D, Series 10, 11, 12, and the Fanuc Series 15-A controls usually have the Part No label mounted along the upper edge of the Fanuc Master PCB. NOTE the parts number on its own for ALL CNC controls is no good without the data sheet also known as the rice paper. if you're wanting to order a full replacement control you will need this as not only does it have all the control hardware details it also has software and options listed.
