Overview: Numerous technologies exist to bar code label industrial tools and components. Standard adhesive labels have poor resistance to abrasion. RFID tags have a limited temperature range [ typ. -40° F to 360° F (-40° to 160° C)] and do not interrogate well when applied or embedded in metal.
Micro2d and Permalabel®: Infosight provides a CO2 laser markable hard anodized media called Permalabel which is marked “subsurface”. The resulting tag with an aluminum oxide surface is immune to scraping—you can actually sharpen a knife on the label!
When supplied as labels with small barcodes , the so-called Micro2d© labels may be affixed with conventional adhesives or with a dot of epoxy (shown) . Micro2d labels are available as unmarked die cut shapes or as sequential preprints. A small circular Micro2d label is shown below affixed to a tool and retains high read rates even after violent in use scraping and toolbox collisions. Samples are available from Infosight ® Corporation* 888 642 3600 ( Becky Dolan) .
