Keyence IV4-G400CA Compact Sensor Head Specs

Product Introduction

The IV4-G400CA serves as a compact sensor head for the Keyence IV4 vision system. Specifically, it pairs with the IV4-G120 amplifier to build a complete inspection solution. This color model delivers high-resolution imaging with a narrow field of view. Furthermore, its zinc die-casting body handles demanding factory conditions.

Technical Specifications

The IV4-G400CA uses a 1/2.9 inch color CMOS image sensor. It captures images at 1280 by 960 pixels. The installed distance starts from 400 mm. At 400 mm, the field of view measures 58 by 44 mm. At 3000 mm, the field of view reaches 464 by 348 mm. These values serve as reference points only. Focus adjustment happens automatically, which simplifies setup. Exposure time ranges from 12 microseconds to 9 milliseconds. The built-in white LED supports pulse and continuous lighting modes. Therefore, users can switch lighting methods to match different targets.

Communication and Electrical Parameters

This sensor head has no built-in communication ports. Instead, it connects to the IV4-G120 amplifier through a dedicated sensor head cable. All protocol and expansion functions run through that amplifier. Power also comes from the connected amplifier. Average power consumption reaches 2.5 W without the AI imaging illumination unit. With that unit installed, consumption rises to 6.6 W.

Mechanical and Environmental Parameters

The main case uses zinc die-casting for structural strength. Meanwhile, the front cover is acrylic, and the operation indicator cover is TPU. This unit meets ESD safety standards under IEC61340-5-1. The weight sits at approximately 75 g without the AI imaging illumination unit. Adding that unit increases weight to about 225 g. For protection, the housing achieves IP67 rating. However, this rating does not apply when polarizing filters are installed. The operating temperature spans 0 to +50°C without freezing. Humidity tolerance stays at 85% RH or less, with no condensation. Vibration resistance covers 10 to 500 Hz at 0.816 G²/Hz across X, Y, and Z directions. Shock resistance handles 500 m/s², three times in each of six directions.

Installation Guide

First, confirm the amplifier model is IV4-G120 before mounting. Next, attach the dedicated sensor head cable to the amplifier port. Then, position the IV4-G400CA at the required working distance. Afterward, secure the mounting bracket to prevent vibration loosening. The auto focus function then adjusts the lens automatically. Additionally, keep the acrylic front cover free of dust and oil. Finally, avoid polarizing filters if the IP67 rating is required.
