Keyence IV4-L6C: Ring Illumination for IV4 Smart Cameras
The IV4-L6C is a white LED ring light built for the IV4-600CA smart camera. It mounts directly to the sensor. No separate power supply. No communication ports. The camera drives it. This keeps wiring simple and cabinet space free. The aluminum die-cast body handles vibration and heat. The acrylic front cover resists scratches. ESD safe per IEC61340-5-1. Ideal for electronics assembly and precision inspection.

Oiltech Controls Review
- The IV4-L6C solves a common problem: uneven lighting on reflective parts.
- Ring geometry gives shadow-free illumination on flat and curved surfaces.
- No extra cables. The camera powers it directly.
- IP67 rating holds up in washdown areas — but only without polarizing filters.
- Best for PCB inspection, connector pin detection, and small part orientation.
Oiltech Controls’s Insight: Compatible Equipment
- IV4-600CA smart camera (direct mount)
- IV4 Series vision systems
- Not compatible with IV3 or older Keyence camera lines
- Polarizing filters OP-88644, OP-88645, OP-88646, OP-88647 reduce IP67 rating when installed
Professional FAQ
Q: Can I use the IV4-L6C with a different Keyence camera?
No. The IV4-L6C is built for the IV4-600CA only. The connector and mounting pattern differ from other Keyence cameras. Using it elsewhere risks no light output or physical damage.
Q: Does the IP67 rating hold with polarizing filters?
No. IP67 applies only when the unit attaches to the applicable sensor without OP-88644/OP-88645/OP-88646/OP-88647 filters. With filters installed, water and dust protection drops. Use in dry areas only.
Q: How do I clean the acrylic front cover?
Use a soft lint-free cloth with mild soap and water. Do not use alcohol or solvents. They cloud acrylic. For stubborn oil, use a tiny amount of dish soap. Rinse with damp cloth. Dry with air or soft tissue.
Q: What should I check before buying a used IV4-L6C?
Inspect the acrylic cover for deep scratches. Check the aluminum case for dents. Verify the connector pins are straight. Ask for a light output test. A dim or flickering ring means LED degradation. Oiltech Controls tests every unit before shipment.
