Keyence IV4-G400MA Sensor Head Monochrome Vision

Keyence IV4-G400MA Narrow Field Sensor Head

The IV4-G400MA is a specialized component within the Keyence IV4 vision sensor lineup. Specifically, this model functions as a compact sensor head for the IV4-G120 amplifier unit. Furthermore, it utilizes a monochrome image receiving element to capture high-contrast grayscale images. This design makes it particularly effective for applications involving dimensional measurement or presence/absence detection. Meanwhile, the narrow field of view allows for precise inspection of small targets at extended distances.

Product Introduction

The IV4-G400MA enhances the flexibility of the IV4 vision system. While the amplifier processes data, this sensor head handles image acquisition. Moreover, the unit requires a minimum installation distance of 400 mm, scaling up to a maximum working distance of 3000 mm. For instance, at 400 mm, the field of view measures 58 mm by 44 mm. However, at 3000 mm, that view expands to 464 mm by 348 mm. Besides, the 1/2.9-inch monochrome CMOS sensor captures images at a resolution of 1280 by 960 pixels, ensuring detailed inspection data.

Technical Specifications and Imaging Performance

The IV4-G400MA relies on advanced imaging technology to deliver stable results. The sensor head features an auto focus adjustment mechanism. Specifically, the focus can be set automatically during installation. This simplifies setup and reduces downtime. Additionally, the exposure time ranges from 12 microseconds to 9 milliseconds. Consequently, the sensor can capture fast-moving objects or adapt to varying lighting conditions. Furthermore, the built-in infrared LED illumination utilizes a pulse lighting method. This approach extends the lifespan of the light source while providing consistent illumination for the monochrome sensor.

Mechanical and Environmental Parameters

Engineered for industrial environments, the IV4-G400MA sensor head offers robust protection. The housing carries an IP67 rating, which ensures resistance to dust and water immersion. However, this rating excludes scenarios where polarizing filters are attached. The main unit case is constructed from zinc die-casting. Additionally, the front cover uses acrylic, and the operation indicator cover is made of TPU. The device operates reliably within a temperature range of 0 to 50 degrees Celsius, provided there is no freezing. Moreover, it withstands relative humidity up to 85 percent without condensation. For vibration resistance, the unit handles frequencies from 10 to 500 Hz across X, Y, and Z directions. Finally, it resists shock forces up to 500 meters per second squared.

Installation and Integration Guide

Integrating the IV4-G400MA into an existing production line requires a few specific steps. First, connect the sensor head to the IV4-G120 amplifier using the dedicated sensor head cable. Because the unit has no built-in ports or communication protocols, it relies entirely on the amplifier for data processing and output. Next, mount the sensor at the desired working distance, ensuring it is at least 400 mm away from the target. During the initial setup, the auto focus function will adjust the lens to produce a sharp image. Furthermore, consider the power consumption, which is 2.5 W without the AI imaging illumination unit and 6.6 W with the unit installed. Finally, verify the IP67 seal is intact after installation to maintain environmental protection.

Packaging List

The standard shipment includes the IV4-G400MA sensor head and protective packaging. Additionally, the package contains the necessary mounting hardware and a product manual. However, please note that the IV4-G120 amplifier is sold separately. Shipping is available via Fedex, UPS, and DHL to ensure timely delivery.
