Keyence IV4-LG4C AI Imaging Illumination Unit

Keyence IV4-LG4C AI Imaging Illumination Unit for IV4 Sensor Heads

Product Introduction

The Keyence IV4-LG4C is an AI imaging illumination unit in the IV4 Series. Keyence built this white LED model to boost image quality on compact sensor heads. It attaches directly to the IV4-HG400CA and IV4-G400CA sensor heads. Therefore, existing IV4 setups gain better lighting without a full hardware change.

This unit carries no built-in ports and no communication protocols. Instead, the connected amplifier supplies all operating voltage. Meanwhile, the sensor head handles image capture and data transfer. As a result, the IV4-LG4C stays simple, compact, and easy to mount.

Technical Specifications

The IV4-LG4C uses white LED illumination. White light preserves natural contrast across colored targets. Furthermore, it helps the AI imaging functions separate real defects from harmless color shifts. This matters on packaging, labels, and printed surfaces.

Compatibility covers two sensor heads: IV4-HG400CA and IV4-G400CA. Besides, the unit draws power from the connected amplifier. Keyence does not publish a separate power consumption figure for this part. In addition, the output type is not available, because the sensor head manages all signal output.

The design carries no built-in ports, no protocols, and no communication expansion. Consequently, installation stays mechanical and electrical only. Technicians simply attach the unit and connect it to the amplifier chain.

Mechanical and Environmental Parameters

The main unit case uses aluminum die-casting and PBT. The sensor head connector combines zinc with nickel plating and PA. Meanwhile, the front cover is acrylic. The cable uses PVC, nickel plating, and TPEE. In addition, the design complies with IEC61340-5-1 for ESD safety.

The IV4-LG4C weighs approximately 150 g. Operating temperature spans 0 to +50°C with no freezing. Relative humidity must remain at 85% RH or less, with no condensation. Moreover, the protection rating reaches IP67, but only when attached to an applicable sensor. However, that rating does not apply when polarizing filters OP-88644, OP-88645, OP-88646, or OP-88647 are installed.

Installation Guide

First, confirm the sensor head is an IV4-HG400CA or IV4-G400CA. Next, align the illumination unit with the sensor head front. Then attach it firmly and lock the connector. After that, connect the cable to the amplifier chain.

Once mounted, power on the amplifier and run a test image. Check brightness uniformity across the full field of view. Meanwhile, adjust the mounting angle if hot spots appear. Finally, verify the IP67 seal sits correctly. If polarizing filters are required, note the reduced protection rating.

FAQ

Q1: Which sensor heads does the IV4-LG4C fit?
It fits the IV4-HG400CA and IV4-G400CA compact sensor heads from the IV4 Series.

Q2: Does the IV4-LG4C need its own power supply?
No. The connected amplifier supplies power through the sensor head chain. No separate supply is needed.

Q3: What LED color does this unit use?
It uses white LED illumination. White light supports natural contrast on colored and printed targets.

Q4: Is the IV4-LG4C IP67 rated?
Yes, but only when attached to an applicable sensor. The rating drops when OP-88644, OP-88645, OP-88646, or OP-88647 polarizing filters are installed.

Q5: How is the IV4-LG4C shipped?
We ship by Fedex, UPS, or DHL. Each unit travels in its original Keyence carton with the full accessory set.
