Code readers
Fixed readers for barcode and 2D codes. Faster to set up than a general smart camera when identification is the only job.
Typical station
Codes on cartons on a conveyor
Cartons pass a fixed reader. Code type, size and working distance are known. The reader sends the decode result to the PLC. On DPM on metal or low contrast, lighting belongs with the reader, not as an afterthought. If you also inspect print or measure around the code, a smart camera is usually the better start. Handheld units are a different form factor. They are not on this page. Background: code readers and DPM reading.
Help with selection
Send samples or a photo of the station. We will say which models fit, and which lens and lighting they need.
