Keyence IV4-L4C Ring Light for IV4 Smart Cameras

Product Introduction

The Keyence IV4-L4C is an external ring illumination unit built for the IV4 Series. This white LED light pairs directly with the IV4-400CA smart camera. Because the sensor supplies power, no separate wiring is necessary. The IV4-L4C improves image brightness and contrast on reflective or uneven targets. As a result, it helps the camera achieve stable inspections in demanding lighting conditions.

Technical Specifications

Illumination Performance

The IV4-L4C uses a white LED array arranged in a ring shape. This geometry delivers even light from all directions around the lens. Consequently, shadows and glare reduce significantly on shiny surfaces. The ring format suits close-range inspection where uniform coverage matters. White illumination also preserves color information for the camera sensor.

Compatibility

This light unit works with the IV4-400CA color smart camera. Keyence designed the mounting interface for direct attachment to that model. No adapter or extra bracket is required for the standard fit. Because power comes from the connected sensor, the IV4-L4C has no independent port or protocol. Communication settings remain on the camera side.

Electrical Characteristics

Power for the IV4-L4C flows from the attached sensor. Keyence does not publish a separate consumption figure for this unit. The light activates through the camera illumination control. Users can switch lighting behavior through the sensor settings. This design keeps wiring simple and reduces installation steps.

Mechanical and Environmental Parameters

Physical Construction

The main case uses aluminum die-casting for strength and heat dissipation. The front cover is acrylic, which protects the LED array. This combination resists vibration and impact on production lines. The IV4-L4C weighs approximately 195 grams. Its compact ring shape adds little bulk to the camera assembly.

Operating Conditions

Moreover, the IV4-L4C operates from 0 to 50 degrees Celsius. Relative humidity should stay at 85 percent or lower without condensation. The unit reaches IP67 protection when attached to a compatible sensor. However, that rating does not apply when polarizing filters OP-88644, OP-88645, OP-88646, or OP-88647 are installed. The light also meets IEC61340-5-1 ESD safety requirements.

Durability Notes

The die-cast housing handles the vibration common on packaging and assembly lines. Acrylic front protection resists scratches during normal use. ESD compliance helps protect sensitive electronics nearby. These traits make the IV4-L4C suitable for continuous factory operation.

Installation Guide

Mounting Steps

First, align the IV4-L4C ring with the front of the IV4-400CA camera. Then attach the unit using the built-in mounting interface. Next, confirm the ring sits flush against the camera body. A flush fit preserves the IP67 seal and keeps illumination even. Finally, tighten the connection to prevent movement during operation.

Power and Setup

No separate power cable is needed for the IV4-L4C. The camera supplies electricity once the unit connects. After mounting, open the camera settings and enable the external light option. Then adjust brightness to match your inspection target. Run a test image to confirm uniform coverage across the field of view.

Alignment Tips

Position the camera so the ring light points straight at the target surface. Tilted angles can create uneven brightness across the image. For reflective parts, try a slight offset to reduce direct glare. Always verify focus after adding the light unit. These steps keep inspection results consistent over long production runs.

FAQ

Question 1: Which camera models work with the IV4-L4C?

The IV4-L4C is designed for the IV4-400CA smart camera. Keyence lists this pairing in the official compatibility data. Other IV4 models may need a different light unit.

Question 2: Does the IV4-L4C require its own power supply?

No. The IV4-L4C receives power from the connected sensor. This removes the need for a separate power cable or adapter. Installation stays simple and clean.

Question 3: What is the protection rating of the IV4-L4C?

The unit carries an IP67 rating when attached to a compatible sensor. However, that rating does not apply when certain polarizing filters are installed. Always check the filter combination before use.

Question 4: What kind of LED does the IV4-L4C use?

The IV4-L4C uses a white LED ring array. This design provides even illumination from all sides. It suits color inspection and reflective surface applications.

Question 5: How much does the IV4-L4C weigh?

The IV4-L4C weighs approximately 195 grams. Its aluminum die-cast body keeps the unit light yet durable. The ring shape adds minimal load to the camera mount.
