Choosing between a used replacement board and a complete new vision sensor is a common fork in machine vision identification projects. You need to know whether your next step is a repair or a full system purchase. The two options here sit at opposite ends of the price scale: the lower-priced control board is 92% below the higher-priced complete sensor, so the decision comes down to matching the part to the job.
Quick Verdict
If you're maintaining an existing VISCOM-based inspection line, the used VTR3 DRV II control board is the low-cost repair path. If you're building or upgrading to a complete inspection application, the Keyence SZ-VH1 gives you a new, model-specific vision sensor rather than just a component. The right answer depends on whether your existing system is the core of your investment or you are starting fresh.

Where Each Product Wins
- VISCOM VTR3 DRV II takes the win for budget-focused repairs. It's a used control board that costs a fraction of the new system, and it gives a specific part number to match VISCOM-based equipment.
- Keyence SZ-VH1 wins when you need a new, complete vision sensor. It is a full system with a clear model designation and Japanese origin, which matters if you need a new complete unit with specific model identification.
Product Notes
VISCOM VTR3 DRV II Control Board
If your machine vision setup includes a VISCOM inspection system, this control board is a specific replacement part: the VTR3 Drv II, with part number T117996. The used condition keeps the price low, which is the main reason to consider it. You are buying a control board, not a complete sensor, so it only makes sense if you already have the rest of the system in place. It is a component for a larger line rather than a standalone identification tool. For a repair budget, the cost is a clear advantage, and the specific model number makes it easier to confirm compatibility with your existing VISCOM equipment.
Keyence SZ-VH1 Vision Sensor
The Keyence SZ-VH1 is a new high-speed vision sensor inspection system. It comes with the Controller Platform set to Automate and is listed as made in Japan. This is a complete system rather than a replacement board, which makes it a stronger fit for a new installation. The high-speed positioning suits production-line identification tasks where speed is critical. The price reflects the fact that you are paying for a full new sensor, not a used component. If you need a clear model number and new condition, this is the complete package to pick. It is the option to choose when your project needs a ready-to-run vision sensor rather than a repair part.
Final Choice by Use Case
Choose the VISCOM VTR3 DRV II if you already own a VISCOM vision inspection system and need a replacement control board without paying for a whole new sensor. Choose the Keyence SZ-VH1 if you are deploying a new inspection application and want a complete vision sensor with a known part number and new condition.
