When a production line needs to identify parts, you have two very different ways to get there: capture an image and let vision software inspect it, or scan a printed code and let the reader decode it. That fork is why the Keyence XG-H2100M and the Keyence SR-X300W are not interchangeable even though both belong in the machine vision identification space. The XG-H2100M is a camera module with a lens, built for image-based inspection. The SR-X300W is a 1D-2D AI powered industrial barcode scanner built for reading codes. The listed price gap is also substantial: the camera is at USD 119.00 and the scanner is at USD 666.00, leaving a spread of about USD 547.
Quick Verdict
If your process depends on checking shape, presence, or surface details in a captured image, the XG-H2100M is the direct image-capture path. If your process depends on decoding 1D or 2D codes, the SR-X300W is the more complete reader.
Comparison at a Glance
| Product | Listed price | Price position | Condition | Best for |
|---|---|---|---|---|
| Keyence XG-H2100M | USD 119.00 | Used | Image capture and inspection | |
| Keyence SR-X300W | USD 666.00 | Used | Barcode decoding |
Where Each Product Wins
- The XG-H2100M wins when the work is visual. You need the lens and camera to feed frames into a machine vision system for presence checks, dimension checks, or surface inspection.
- The SR-X300W wins when the work is code-based. You need a scanner that reads barcodes and processes them on the unit.
Product Notes
Keyence XG-H2100M Industrial Machine Vision Camera Module w/ Lens
The XG-H2100M is a machine vision camera module, and the included lens gets you closer to an inspection setup. It was recently retired from service by a local business, so this is a used unit that comes as pictured. That is also the main limitation: nothing additional is included, so cabling, mounting, and the vision processing environment are on you. If your project needs a camera to check part presence, measure features, or inspect surfaces under controlled lighting, this module is a straightforward way into a Keyence vision platform. Just plan to supply everything beyond the module and lens.
Keyence SR-X300W 1D-2D AI Powered Industrial Barcode Scanner
The SR-X300W is built as a 1D-2D AI powered barcode scanner, so it is designed to decode labels and direct part marks without a separate vision processing unit. The used unit shows cosmetic flaws and is missing a button, and the seller makes clear that manufacturer warranty and support do not apply. That makes it a hardware-as-is purchase. If your line needs reliable reading of 1D or 2D codes and you want the AI-assisted decoding capability, this scanner is the more complete ready-to-deploy pick. Give the missing button and cosmetic condition a close look before putting it into full production.
Final Choice by Use Case
Choose the XG-H2100M if your core need is image capture for inspection and you can build the surrounding vision setup. Choose the SR-X300W if your core need is reading barcodes and you want a single scanning unit. When both roles matter, decide by the more frequent or more critical step on your line: a camera cannot decode a barcode, and a scanner cannot inspect a surface.
