High precision marking solution for traceability and identification of any part
The XF510m offers the precision and quality that electromagnetic micro-percussion can bring. The force of the impact can be adjusted in hundredths via the precision control unit. This means it can be used on even the most delicate materials. This technology simply requires an electrical supply. This range is particularly suited to the marking of 2D codes (Data MatrixTM ECC200, UID etc.).
3 Marking areas available : 50 x 20 mm / 100 x 80mm / 200 x 80 mm
