Image-based code readers

High efficiency for code reading applications

Your Benefits

  • Highly flexible code position, object height, and transport speed due to a large field of view and large depth of field
  • Cost-effective, straightforward, modular integration of multiple devices adapted to the width of the conveyor belt
  • Minimum training and installation work due to intuitive device equipment that includes function buttons, auto setup, integrated illumination, an aiming laser, an acoustic feedback signal, and a green feedback LED
  • Intelligent decoding algorithms ensure maximum reading performance and high package throughput, even with codes that are difficult to read
  • SICK 4Dpro platform facilitates quick and easy integration into numerous industrial networks


High efficiency for code reading applications

The Lector642 image-based code reader from SICK provides maximum performance and optimum throughput in logistics and factory automation. With a frame repetition rate of 40 Hz and real-time decoding, the Lector642 can reliably identify 1D, 2D and directly marked codes at the highest possible speed. The 1,7 megapixel image resolution offers a large field of view. The intuitive device equipment – featuring function buttons, auto setup, an aiming laser, an acoustic feedback signal, and a green feedback LED – reduce the amount of work required for training and installation. The microSD memory card can be used to store images or back-up copies of parameters. Due to SICK's 4Dpro feature, the Lector642 can be integrated into numerous industrial network.
