All-in-one solution
There is no need to worry about installation, use, or training.
KEYENCE IV4 AI Vision Sensor
AI reads even blurred print. Automatically check expiration dates, lot numbers, and printing defects on the line. PEC handles installation, training, and ongoing support.

1 machine handles 400 packs/min previously checked by 10 inspectors
At least KRW 2,000,000 in monthly labor savings
Inspection miss rate achievable with a properly configured system
Sensors are widely available, but a vision inspection system needs to be designed and integrated for your line. With 30 years of packaging-line experience, PEC handles the sensor and its integration together.
| Item | Buy only the sensor directly | PEC All-in-One Solution |
|---|---|---|
| Bracket·Installation location | There is no bracket to match the line, so you have to adjust the angle, distance, and lighting yourself. Most people get stuck here. | We design·build brackets for your production line and install them at the best angle and position for reliable reading. |
| Marking machine·labeler integration | It is meaningless if you only inspect and fail to filter out defects. Signal connections between devices are a separate task. | We connect marking machines, labelers, and conveyors via EtherNet/IP so defective products are stopped or rejected before shipping. |
| Setup·Training | You must learn OCR learning, judgment criteria, and item change settings by looking at the manual. | We configure inspection criteria for expiration dates, lot numbers, and print defects, then train your operators to switch products. |
| After-Installation Support | If the product or packaging material changes, it has to be adjusted from the beginning again, and there is no one to ask questions. | PEC continues to manage packaging material changes, new product additions, and judgment errors even after installation. |
| Result | Buying just the sensor may save upfront cost, yet often fails to deliver a working inspection line. | Inspection begins on the line from the day of installation, immediately reducing inspector labor costs. |
There is no need to worry about installation, use, or training.
We design·install brackets for your line to inspect from the best angle and position.
We support every stage of IV4 operation, from EtherNet/IP connection to sensor settings.
Even after installation, we continue to manage it to ensure it operates in optimal condition.

AI learns defects quickly, and high-precision OCR reads blurred print. Integrated lighting·lens·camera allow setup without specialist knowledge.

Inspect printed expiration dates, lot numbers, engravings, and serial numbers, plus visible defects such as creases, dents, scratches, sealing flaws, and contamination.

Check whether your customer's quality standards require OCR, whether suitable brackets are available, and whether training and support continue after setup.
IV4 vision inspection is being installed on leading Korean OEM lines, including CJ, Daesang, and Harim.
It inspects printed characters such as expiration dates, lot numbers, engravings, and serial numbers, as well as visible defects such as creases, dents, scratches, sealing flaws, and contamination.
The high-precision OCR of the KEYENCE IV4 AI Vision Sensor reads even faintly printed characters. With lighting, lens, and camera integrated, it can be set up without specialist knowledge.
You can, but you would have to handle the line-specific bracket, angle·distance·lighting, signal connections between machines, and setting of judgment criteria yourself. PEC takes care of everything from bracket design·installation to setup, training, and post-installation support.
We connect marking machines, labelers, and conveyors via EtherNet/IP so defective products are stopped or rejected before shipping.
We design brackets to fit your line and install them on site. In one case, adding OCR inspection to an egg packaging band marking line brought existing equipment back into use.
Yes. There is a case study on an herb-salt container line where only products missing a seal liner are removed automatically. It can be configured together with an induction sealer.
We train your on-site staff so they can change product settings themselves. PEC also continues to support packaging changes, new product additions, and judgment errors after installation.
When configured with a marking machine and labeler, printing defects are filtered out before shipping.
