Symbol LS4278 barcode scanner from Motorola

Symbol LS4278 barcode scanner from Motorola


The Symbol LS4278 barcode scanner is specially designed to deliver exceptional scanning performance. With this device users can scan objects at any angle, the innovative multi-line rastering scan pattern eliminates the need for exact aim and positioning of the scanner. The laser line moves vertically during scanning, allowing accurate capture of even the smallest, stacked and poorly printed barcodes on the first scan. And with superior motion tolerance, users no longer need pause between scans, further increasing productivity.

The Symbol LS4278 scanner and cradle are designed to withstand all day every day use, from drops to spills, with features that deliver maximum uptime and investment protection.

The scanner’s patented single board construction eliminates the most common point of failure, the interconnection between multiple boards. Even if the scanner is accidentally dropped, a five-foot (1.5m) drop specification ensures continuous reliable operation.


The scanner and cradle offer industrial charging contacts that eliminate wear when cradling the device, providing a reliable charging connection through hundreds of thousands of insertions, other common charging techniques show wear between 5,000 to 10,000 insertions. Drain points are designed into the cradle to protect sensitive internal electronics from accidental liquid spills.

Its integrated Bluetooth wireless personal area networking (WPAN) provides reliable and secure wireless transmission of data between the scanner and your host. With this device workers can move within a 50 ft./15 m radius to scan items and best of all eliminates the need of hazardous cables helping to create a safer work environment.
