IV4-G400CA Keyence Compact Color Sensor Head – IV4 Series
The Keyence IV4-G400CA is a compact color sensor head for the IV4-G120 amplifier. It offers a narrow field of view. It starts at a 400 mm install distance. The unit uses a 1/2.9 inch color CMOS sensor with 1280 x 960 pixels. Auto focus and white LED lighting simplify setup. It suits color inspection, presence checks, and positioning tasks. The IV4-G400CA connects to the amplifier via a dedicated cable. All outputs and communication go through the amplifier.

Oiltech Controls’s Insight
The IV4-G400CA is a smart pick for engineers who need color vision at moderate range. The 400 mm start distance avoids close-proximity mounting issues. The narrow FOV helps isolate small features. Auto focus cuts commissioning time. The IP67 body handles washdown areas, but you lose that rating with polarizing filters. Plan your filter use carefully. The head draws up to 6.6 W with AI illumination. Check your amplifier budget. The 75 g weight keeps robot arm loading low. For legacy IV4 systems, this head drops in without rewiring.

FAQ
Q: Can I use the IV4-G400CA without the IV4-G120 amplifier?
No. The head has no built-in ports or output circuits. It needs the IV4-G120 for power, image processing, and I/O. Buying the head alone will not work.
Q: Does the IP67 rating still apply if I add a polarizing filter?
No. Keyence states the IP67 rating is void when you install OP-88642, OP-88643, OP-88646, or OP-88647 filters. Use filters only in dry areas, or add a separate enclosure.
Q: What is the real benefit of the narrow field of view?
A narrow FOV gives higher pixel density on small targets. At 400 mm, you see 58 x 44 mm. That helps detect fine color marks, small labels, or tiny part features. For wide scenes, move the head back to 3000 mm.
Q: How do I choose between the IV4-G400CA and a wider FOV model?
Match the FOV to your smallest feature. If your target is under 10 mm, the narrow FOV wins. If you inspect large pallets or wide webs, pick a wider model. Also check the 400 mm minimum distance against your mounting space.
Q: What should I check before buying a used or surplus IV4-G400CA?
Ask for the sensor head cable, the amplifier model, and a test image. Confirm the LED works and auto focus moves freely. Check the front acrylic for scratches. Verify the firmware pairs with your IV4-G120. Oiltech Controls tests each unit before shipment.
