IV4-G400MA Keyence Compact Sensor Head – Narrow Field of View for IV4-G120 Amplifier
Model: IV4-G400MA | Brand: Keyence | Series: IV4 Series
This IV4-G400MA is a compact sensor head for the IV4-G120 amplifier. It uses a 1/2.9 inch monochrome CMOS with 1280 x 960 pixels. The narrow field of view suits precise positioning, presence checks, and small part inspection. It has auto focus, infrared LED illumination, and pulse lighting. The unit connects to the amplifier with a dedicated sensor head cable. It has no built-in ports or protocols. Power comes from the connected amplifier. The IP67 rating handles washdown and dusty areas. This sensor head is active in Keyence production as of September 2026.

Oiltech Controls Review
- Engineers choose this head for tight spaces and short range
- The narrow FOV reduces false triggers on busy lines
- Auto focus cuts setup time after head changes
- Infrared LED works well in low-light cells
- Pulse lighting freezes motion without blur
- Pairs with IV4-G120 for AI imaging tasks
Oiltech Controls’s Insight
- Use this head when the target is small or far
- The 400 mm minimum distance needs a stable mount
- Exposure time from 12 µs to 9 ms covers fast and slow lines
- Add the AI imaging illumination unit for difficult surfaces
- Check IP67 limits when polarizing filters are installed
- Keep spare cables for quick swap during shift changes

FAQ
Q: Does the IV4-G400MA work without the IV4-G120 amplifier?
A: No. It needs the IV4-G120 for power, control, and output. The head has no standalone output.
Q: What is the minimum installation distance?
A: 400 mm. Closer mounting will not focus correctly. The field of view grows as distance increases.
Q: Can I use this head outdoors or in wet areas?
A: It is IP67 rated, so it handles washdown and dust. But when you install polarizing filters, the IP67 rating does not apply.
Q: How do I choose between the standard and AI illumination version?
A: Pick the AI imaging illumination unit for shiny, low-contrast, or uneven surfaces. It raises power use to 6.6 W and weight to 225 g.
Q: What should I check before buying a used or surplus IV4-G400MA?
A: Confirm the front cover is clear and the cable connector is undamaged. Ask for a test image from the seller. Verify the auto focus moves smoothly. Check the zinc case for cracks or impact marks.
