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 has specific advantages and disadvantages in terms of durability. cost and ease of reading.The PowerScan™ PD9530-DPM Evo reader is a rugged handheld area imager specifically addressed for DPM applications. The typical reading distance is from contact to 4-5 cm / 1.5-1.9 in. depending on the type of DPM technology used. the code resolution. and the material and surface type. The scanner is also capable of reading standard bar codes printed on labels. It is based on a high density optic which allows the capture of very small. high-resolution codes in a range from near contact up to 15.0 cm / 5.9 in.The intuitive aiming system provides the highest first-pass reading rate. Additionally. the PowerScan 9530-DPM Evo area imager uses a soft-pulsed white illumination light resulting in reduced flashes. which is very gentle on users’ eyes.Datalogic’s Motionix™ motion-sensing technology detects the natural actions of the operator to automatically switch the scanner into the desired scanning mode.
