When your production line depends on reliable barcode reads, picking the right scanner for your machine vision identification setup is a big deal. The SICK CLV490-6010 Industrial Barcode Scanner, V#6, is a used line-scan unit that shows up at a modest price, but you have to decide whether an older, discontinued scanner can still handle the job.
Quick verdict
The SICK CLV490-6010 is a SICK line scanner priced at USD 279.00 in used condition. It is built for low-density barcode reading and supports a program-selectable host connection, which gives you flexibility in integrating it with your automation gear. The manufacturer has discontinued this model, though, so you are buying a unit with limited long-term support and some risk that comes with used hardware.
Who it suits
If you already run SICK equipment and need a familiar spare or a secondary scanner, this model is a reasonable candidate. It also appeals to small automation projects where the budget is tight and you are comfortable commissioning used industrial hardware yourself.

For USD 279.00, this used scanner gives you a real SICK unit, not a generic look-alike. The line-scan approach lines up well with reading barcodes on items moving along a conveyor, and the low-density rating tells you it handles standard barcodes rather than ultra-dense codes. The program-selectable host interface lets you choose how the scanner talks to your controller, which is a useful option to have.
The big reason to be cautious is the condition: this is explicitly a used unit. On top of that, the manufacturer has discontinued the model, so getting spare parts or support from SICK will be difficult if anything fails. You are paying a low price, but you are also taking on the risk that the internal optics or electronics may have wear that only shows up after you install it.
What stands out
The model number, manufacturer, and MPN are all consistent on this unit, so there is no ambiguity about what you are looking at. The combination of line scan, low density, and program-selectable host is clearly stated, giving you a concrete picture of its intended use. The price is also a standout: USD 279.00 is a relatively small amount for industrial barcode scanning hardware.
Meaningful trade-offs
The most obvious trade-off is the used condition. With any used scanner, you cannot know how much the laser or sensor has aged until you power it up. The discontinued status adds another layer of risk because replacement parts and official config software may not be available. The low-density limitation also narrows the range of barcodes it can handle, so if your labels pack a lot of data into a small space, this scanner will not be the right tool.
Another trade-off is the line-scan design itself. It works well for products passing in front of the scanner, but it is not as versatile as an area imager for reading codes at random angles. The program-selectable host is a positive, but the exact host protocols are not specified, so plan to spend some time with SICK's setup tools.
Bottom line
The SICK CLV490-6010 is an affordable entry into industrial barcode scanning at a selling price of USD 279.00. It is a SICK product with a clearly labeled used condition and a discontinued status, so it makes sense only if you accept those realities. If you need a low-density line scanner for a defined machine vision identification task and you are comfortable working with used gear, this unit is a reasonable buy. If you need manufacturer support, high-density reading, or fresh hardware, you should skip it.
