IV4-L4C Ring Light for Keyence IV4 Smart Camera
The IV4-L4C is a white LED ring light from the Keyence IV4 Series. It delivers stable, shadow-reduced illumination for the IV4-400CA smart camera. The unit draws power directly from the sensor. No separate power supply is needed. Its IP67 rating supports harsh factory floors. The aluminum die-cast body and acrylic front cover resist vibration and dust. ESD-safe design meets IEC61340-5-1. This makes the IV4-L4C a practical choice for inline inspection, code reading, and presence detection.
