When you're putting together a machine vision identification setup, the first fork in the road is whether you need a complete imaging reader or just the cable that connects the camera you already have. That's the choice between the Cognex DataMan DM474QL-M and the Keyence CA-CH3 3M/10ft cable. The price difference is real - the Cognex reader is listed at $255.00, while the Keyence cable is listed at $34.52 - but the actual decision depends on which piece your system is missing.
Quick Verdict
If your machine vision identification task requires a dedicated sensor that can capture and identify objects, the Cognex DataMan DM474QL-M is the unit to build around. If you already have a KEYENCE CA Series camera and simply need to replace or extend the 10ft connection, the Keyence CA-CH3 is the economical pick. Both are listed as used, so factor that into your plan.
Comparison at a Glance
| Product | Listed Price | Condition | Role |
|---|---|---|---|
| Cognex DataMan DM474QL-M | $255.00 | Used | Industrial machine vision imaging camera reader sensor |
| Keyence CA-CH3 3M/10ft Cable | $34.52 | Used | Machine vision camera cable for KEYENCE CA Series |
Where Each Product Wins
- Choose the Cognex DataMan DM474QL-M when your line needs a reader that performs precise inspection and identification in manufacturing, quality control, and automation. It's the higher-priced item, but it's also the one that does the imaging work.
- Choose the Keyence CA-CH3 when you're working with an existing KEYENCE CA Series camera and money is better spent on a 10ft replacement cable than on a full reader. Its lower price makes it the sensible pick.
Product Notes
Cognex DataMan DM474QL-M Industrial Machine Vision Imaging Camera Reader Sensor
With the DataMan DM474QL-M, you're getting a full industrial machine vision imaging camera reader sensor rather than a support component. It is built for precise and efficient inspection and identification in manufacturing, quality control, and automation, so it fits a role where objects need to be read and recognized on the line. The MPN DM474QL-M gives you a specific model reference, and Cognex is the supplier. The limitation is the higher price: it's the bigger investment here, so it only makes sense when your setup actually needs the reader function. If your machine vision identification task is missing a sensor, this is the product that fills that gap.
Keyence CA-CH3 Machine Vision Camera Cable 3M 10ft
The Keyence CA-CH3 comes as a 3-meter/10ft cable in good working condition with no visible damage. Its compatibility with KEYENCE CA Series machine vision cameras makes it a replacement option for that camera family. As the lower-priced option, it's the easier buy when the budget is tight. The trade-off is that a cable cannot capture images or read anything by itself; it exists to link a camera to your setup. It also carries a KEYENCE-specific compatibility listing, so it's not a universal cable for unrelated systems. When the camera is already on hand and the missing piece is the link, this cable covers that need without a large outlay.
Final Choice by Use Case
If the gap in your machine vision identification line is the imaging and reading capability itself, the Cognex DataMan DM474QL-M is the one to choose. If you're maintaining a KEYENCE CA Series camera and need a 10ft cable, the Keyence CA-CH3 is the practical buy.
