Quick take
Choosing the right machine vision identification components means deciding whether you need to capture an image or correct the image your current camera already sees. The four options here cover very different jobs: two Keyence camera bodies, a Cognex color camera, and a pair of lens calibration targets. If your task is color inspection, the Cognex unit is the only one whose title promises a color camera. If you are building a low-budget setup, the Keyence XG-H2100M is the entry point. And if your existing images look distorted or color-shifted, the calibration boards may be the missing piece.
Listed Price Comparison
| Product | Listed Price | Price Bar |
|---|---|---|
| Keyence XG-H2100M Industrial Machine Vision Camera Module w/ Lens | USD 119.00 | |
| Pair of Machine Vision Lens Distortion Calibration Target Boards w/ ColorChecker | USD 180.00 | |
| KEYENCE MACHINE VISION CAMERA WITH LENS CA-HX200M W/F1.4/12MM | USD 249.99 | |

Decision Matrix
- Color inspection is the core task: The Cognex IS7802C-363-50 Color Machine Vision Camera is the only product here whose title says Color, making it the natural first candidate.
- Budget is the main constraint: The Keyence XG-H2100M sits at the low end of this price range and is still a Keyence camera module with a lens.
- Your lens needs checking before you trust a captured image: The Pair of Machine Vision Lens Distortion Calibration Target Boards w/ ColorChecker lets you evaluate distortion and color balance in one used set.
- You want a ready-to-mount camera with a brighter aperture: The KEYENCE MACHINE VISION CAMERA WITH LENS CA-HX200M W/F1.4/12MM pairs a camera with a 12mm F1.4 lens.
Product Notes
Pair of Machine Vision Lens Distortion Calibration Target Boards w/ ColorChecker
These calibration boards solve a different part of machine vision identification than the cameras: they help you check lens distortion and color reference before you trust what the camera sees. The pair includes built-in ColorChecker targets, LED grid illumination, and battery power via AA batteries, and the condition is listed as used but fully operational. That makes them a practical companion to any of the cameras in this comparison. The limitation is obvious but worth stating: they are targets, not capture hardware. You need a camera such as the Cognex or Keyence models here to actually record an image, and the boards do not replace a color camera when your inspection task requires live color classification.
KEYENCE MACHINE VISION CAMERA WITH LENS CA-HX200M W/F1.4/12MM
The Keyence CA-HX200M is a camera-plus-lens bundle that sits in the middle of this price spread, and the included 12mm F1.4 lens is the standout detail for low-light or fast-moving part identification. It is a used industrial surplus unit from American Industrial Supply Co., and the description says the items shown in the photos, namely the camera and lens, are what you get. If your application already assumes a Keyence controller or software workflow, staying with a Keyence camera body reduces integration variables. The limitation is the opposite side of the same coin: because it is described simply as a machine vision camera with a lens, there is no color-specific claim, so it should not be your default if color matching is the central requirement.
Cognex IS7802C-363-50 Color Machine Vision Camera 825-10786-1R Opto TC23016 Lens
This Cognex IS7802C-363-50 is the one product in the group with a clear color-camera identity, and it ships with an Opto TC23016 lens. The description says the unit is in excellent cosmetic condition, works, and was removed from a working environment, which is a useful confidence signal for a used industrial camera. If your identification task involves reading colored status lights, sorting parts by hue, or checking printed labels, the color sensor is the differentiator the other camera bodies do not claim. The limitation is the high end of the price range; it is the most expensive option in this set, so it should be reserved for applications that genuinely need color discrimination rather than simple presence or geometry checks.
Keyence XG-H2100M Industrial Machine Vision Camera Module w/ Lens
The XG-H2100M is a Keyence industrial machine vision camera module with a lens shown in the picture, and it sits at the low end of this comparison's price range. A local business retired it from service recently, so it is a used unit, and the description says it comes exactly as pictured with nothing additional included. For an engineer who already has a Keyence XG controller or wants to prototype an identification setup without a large budget, this module is the least expensive camera path. The limitation is that the description does not state a focal length or aperture for the lens, so you are relying on the pictured lens already matching your working distance and field of view.
Final Recommendation
For color-critical identification, start with the Cognex IS7802C-363-50 Color Machine Vision Camera. For a low-budget camera path, use the Keyence XG-H2100M. If you already have a camera and only need to verify lens geometry, get the Pair of Machine Vision Lens Distortion Calibration Target Boards w/ ColorChecker. And if you want a Keyence camera with a bright 12mm F1.4 lens in one package, the KEYENCE MACHINE VISION CAMERA WITH LENS CA-HX200M W/F1.4/12MM is the balanced middle option.
