SICK CLV650-6120 Sensor
SICK CLV650-6120 barcode scanner, part 1042125. Fixed-mount 1D scanning with autodynamics for packaging and intralogistics.
Overview
The SICK CLV650-6120 (part number 1042125) is a fixed-mount barcode scanner of the CLV650 family for industrial goods identification. With autofocus and autodynamics, it reads 1D barcodes reliably on moving products and integrates into conveyor, packaging and intralogistics systems.
How It Works
A laser scan line sweeps the barcode on the passing product; the reflected signal is decoded and transferred to the control system. The autofocus keeps the scan line sharp across the working range, and autodynamics match the decode behavior to the actual product speed.

Installation and Setup Notes
Position the scanner so the scan line meets the code with the recommended tilt to avoid specular reflection. Configure symbologies, interface and output format with the family software, and validate read rate statistics during live operation before go-live.
Frequently Asked Questions
What is the difference from the CLV630?
The families differ in reading performance and range classes; the order code defines the exact optics and interface.
Can it read stacked or truncated codes?
The decoder handles a wide range of print qualities, including truncated codes, within its specification.
Is it suitable for 2D codes?
The CLV650 reads 1D barcodes; for 2D symbols use an image-based code reader such as the V2D6xx family.
