Direct Part Marking (DPM) is a process that allows users to imprint a bar code directly on an item instead of printing the code on a paper label. Different technologies are available to directly mark objects: laser/chemical etching, dot peening and ink jet printing. Each of these methods have specific advantages and disadvantages in terms of durability, cost and ease of reading.
The PowerScan™ 9501-DPM Evo series of scanners are rugged handheld area imagers specifically addressed and capable of reading codes marked with DPM. The Datalogic Powerscan PTB9501 DPM offers a bluetooth connection. Please see brochure below for full spec.
