Every HEIDENHAIN product bears an ID label. On this label you can find data identifying the unit.
Model designation
The model designation is the name of the device.
ID number
The ID number (also referred to as part number) is a HEIDENHAIN article number consisting of the basic ID number (6 or 7 digits) and the variant (2 digits after the hyphen). If you intend to order a replacement unit from HEIDENHAIN, the ID number is absolutely necessary, as it allows for an exact statement on the product’s specifications. The ID number may be abbreviated to ID, ID number or Id.No.
Serial number
Every device has its own serial number. The serial number is a consecutive number for unique identification of products with the same ID number. It serves to ensure traceability of a product after it has been put in circulation, e.g. to find the date of invoice that is required to determine guarantee and warranty periods. The term serial number is mostly abbreviated to SN or S/N.
Model designation, ID number and serial number are also indicated on the packaging label.
