Keyence SR-651 2D CMOS barcode scanner 752×480 630 nm

SKU CH-0XRY-3D732 MPN SR-651

A 2D CMOS code reader with a 752×480 sensor and 630 nm red LED illumination

  • High-resolution 752×480 CMOS sensor captures detailed 2D codes
  • 630 nm high-intensity red LED illuminates barcodes evenly
  • Class 1 LED rating ensures eye-safe operation
  • SR-651 model reads Data Matrix and QR symbols reliably
  • New condition with 90-day seller warranty included

Product identity

The Keyence SR-651 is a new 2D barcode scanner built around a CMOS image sensor with a 752×480 pixel array. A high-intensity red LED at 630 nm provides illumination for reliable code reading. It is supplied as a standalone code reader for integration into automated identification workflows.

Who it suits

This scanner suits engineers adding fixed-mount 2D decoding to conveyor lines, kiosks or inspection stations where a compact CMOS imager and 630 nm red lighting meet the application needs. Buyers who require an integrated aiming laser, a different wavelength or a wider field of view should look at alternative models.

Deciding specification

The 752×480 pixel CMOS sensor resolution determines the smallest code module the reader can resolve and the maximum capture speed for moving items. Match that figure to your symbol density and line velocity to confirm the SR-651 is the correct part.

Questions about this item

How can I confirm the SR-651 is reading codes correctly after installation?

Aim the scanner at a test Data Matrix or QR code; the high-intensity 630 nm red LED illuminates the symbol and the 752×480 CMOS sensor captures the image, triggering a good-read output when decoding succeeds.

What does the SR-651 package contain and what must I source separately?

The unit includes the SR-651 code reader with its integrated Class 1 630 nm LED and 752×480 CMOS imager; cables, mounting brackets and any interface modules are not included and must be purchased separately.

Which SR-651 variant should I select for my application?

The SR-651 is offered as a single 2D CMOS model with a 752×480 pixel sensor and 630 nm illumination; choose it when you need a compact Class 1 LED reader for standard-range 1D and 2D code capture.
