The SR-750 Series compact 1D and 2D code reader offers stable automatic reading of challenging codes despite its compact size. Adopting a new image capturing and processing algorithm and using the latest correction techniques, this series achieves best-in-class reading performance for the most difficult-to-read codes. This code reader can reliably read codes directly marked on products (DPM) of various materials. Operators can also use the easy tuning feature which provides optimal settings in three steps either on the unit itself or from a computer, thereby resulting in quick integration and product changeovers. This series is also the first unit in its class to be equipped with a marking quality judgment function based on industry standards. This function outputs judgment results as signals and can be useful for predictive maintenance of the marking process.
