Hauppauge, New York – SBSI series low cost vision sensors for code reading and quality inspection feature fast setup, compact sizes, rugged IP67 housing, built-in lighting, and EtherNet/IP capability. SBSI sensors can be ordered as components, parts of a sub-system ready for assembly, or incorporated into a plug and play module.

The SBSI-B reads 1D and 2D codes. These code readers can be used to identify and track and trace products for production flow, logistics, and serialization. The SBSI-B can also read direct part marking (DPM) codes, including laser etched and dot-peened codes, and can check for the quality of a DPM code.

The SBSI-B reads up to 10 codes per image. SBSI-B readers are designed for automated solutions in the automotive and other industries.

The SBSI-Q for quality inspection can be used for completeness and presence sensing to ensure all relevant parts are mounted and/or accounted for. Position checking can verify if caps are correctly mounted or screws and holes are in the right position. The SBSI-Q can compare an object’s contour with taught-in reference contour, and can compare patterns and evaluate pixels within the search area by calculating contrast, brightness, or variations in gray scale.

SBSI series optics offer a range of reading areas and working distances. Code reading models have enhanced depth of field to increase the area of focus. Built in lighting comes in white, red, or infrared. There are also a range of options for additional lighting, including ring lights and area lights. All additional lights are plug and play. The SBSI housing is exceptionally small and rugged with an IP67 rating for automotive and food and beverage applications.

All key functions, including processing, lighting, and optics, are integrated. There are status and I/O indications. Working distance is adjustable. SBSI sensors have two inputs and four outputs with two PNP/NPN switchable I/O. Users have many options for communications protocols, including Industrial Ethernet – EtherNet/IP, TCP/IP, FTP, SMB – digital I/O, and RS232/422 (code reader model only). SBSI software is intuitive to use with set-up only requiring three to four steps.
