Keyence IV4-LG4M AI Imaging Illumination Unit

Keyence IV4-LG4M AI Imaging Illumination Unit for IV4 Sensor Heads

Product Introduction

The Keyence IV4-LG4M is an AI imaging illumination unit within the IV4 Series. Keyence designed this infrared LED model for compact sensor heads that need hidden or low-glare lighting. It mounts onto the IV4-HG400MA and IV4-G400MA sensor heads. Therefore, existing monochrome IV4 setups gain stronger imaging without a full hardware swap.

This unit carries no built-in ports and no communication protocols. Instead, the connected amplifier supplies all operating voltage. Meanwhile, the sensor head manages image capture and signal output. As a result, the IV4-LG4M stays compact, simple, and fast to install.

Technical Specifications

The IV4-LG4M uses infrared LED illumination. Infrared light stays invisible to the human eye, so it will not distract operators. Furthermore, it reduces glare on shiny metal, glass, and polished plastic. This matters on reflective surfaces where white light creates hot spots.

Compatibility covers two sensor heads: IV4-HG400MA and IV4-G400MA. 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 handles all signal output.

The design carries no built-in ports, no protocols, and no communication expansion. Consequently, installation remains 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-LG4M 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-HG400MA or IV4-G400MA. 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 dark corners 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-LG4M fit?
It fits the IV4-HG400MA and IV4-G400MA compact sensor heads from the IV4 Series.

Q2: Does the IV4-LG4M 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 infrared LED illumination. Infrared light is invisible and reduces glare on reflective surfaces.

Q4: Is the IV4-LG4M 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-LG4M shipped?
We ship by Fedex, UPS, or DHL. Each unit travels in its original Keyence carton with the full accessory set.
