The LS 4000 Series is the result of Symbol's experience in the design of innovative, high-performance scanning solutions. The LS 4000 incorporates a 650 nm laser that provides a bright scan line ensuring easy aiming even in high ambient light conditions. Combine this with a robust working range of contact out to more than 16 in. (40 cm) on 100% UPC codes and bar code data capture is a snap. Plus built-in Adaptive Logic Signal Processing decodes poorly printed and damaged bar code.
