Features
● Optical sensor for scanning bar codes
● Comprises a laser diode with optics, as well as an electronics unit with integrated
decoder. Both components are installed in a housing
● Light is emitted and received through the viewing window in the housing

Function
● Automated and non-contact detection and decoding of bar codes on a conveying line
after triggering
● A scan line is generated on the object in order to detect the bar code
● Auto focusing when the light beam hits the object
● The line pattern reflected from the bar code is recorded, processed, and decoded by the
CLV691
● The read result is transmitted to the MSC800 system controller
