Keyence IV4-400CA Smart Camera Color

Keyence IV4-400CA AI Vision Sensor

Product Introduction

The Keyence IV4-400CA is a narrow field of view smart camera from the IV4 Series. This color model integrates AI processing directly into the sensor body. As a result, engineers deploy it for inline inspection without a separate vision controller. The unit handles presence checks, sorting, and counting tasks on high-speed lines.

Technical Specifications

Imaging Performance

The IV4-400CA uses a 1/2.9 inch color CMOS sensor with 1280 x 960 pixels. Its narrow field of view starts at an installation distance of 400 mm. Specifically, the view covers 58 x 44 mm at 400 mm and expands to 464 x 348 mm at 3000 mm. Focus adjustment is automatic, which simplifies setup during changeovers.

Exposure and Illumination

Exposure time ranges from 12 µs to 10 ms, allowing capture of fast-moving targets. A built-in white LED provides illumination. Moreover, the lighting method switches between pulse and continuous modes. This flexibility supports both freeze-frame inspection and steady illumination for static measurement.

Tools and Modes

The camera offers 65 tools for flexible inspection setup. Operators can choose Standard Mode, Sorting Mode, or AI Through Count Mode. Additionally, the AI engine learns acceptable part variation, which reduces false rejections on textured or reflective surfaces.

Communication and Electrical Parameters

Built-in Ports and Protocols

An M12 8-pin X-code female Ethernet connector handles data transfer at 1000BASE-T or 100BASE-TX. The IV4-400CA supports EtherNet/IP, PROFINET CC-B, and TCP/IP non-procedural communication. Furthermore, it offers FTP client, SFTP client, SNTP client, OPC UA server, and MQTT client functions.

Communication Expansion

For additional fieldbus support, the IV4-CU1 communication unit adds PROFINET CC-C and EtherCAT. Besides, DL Series units enable EtherCAT, CC-Link, DeviceNet, and RS-232C connections. Therefore, the camera integrates with most factory control architectures.

Power and I/O

The unit runs on 24 VDC +25%/-20% including ripple. Power draw reaches 3.4 A or less at 19.2 V, and 2.7 A or less at 24.0 V. Average consumption is 9.3 W without the AI imaging illumination unit, rising to 12.8 W with it. PoE Power Class 4/6 is also supported.

The IV4-400CA provides six inputs and six outputs, with three selectable IN/OUT lines. Outputs use open collector design with NPN/PNP and N.O./N.C. switching. Maximum output rating is 30 V at 50 mA.

Mechanical and Environmental Parameters

Protection and Durability

The housing carries an IP67 rating, except when polarizing filters OP-88640, OP-88641, OP-88644, or OP-88645 are installed. Vibration resistance covers 10 to 500 Hz at 0.816 G²/Hz across X, Y, and Z directions. Shock resistance reaches 500 m/s², tested three times in each of six directions.

Operating Conditions

Operating temperature spans 0 to +50 °C with no freezing permitted. Relative humidity must stay at 85% RH or less without condensation. These limits suit typical machine vision installations inside production cells.

Physical Construction

The main case uses aluminum die-casting for rigidity. The front cover is hard-coated acrylic, while the back cover and lid use PBT. The unit is ESD safe and complies with IEC61340-5-1. Weight is approximately 370 g without the AI imaging illumination unit, or 560 g with it.

Installation Guide

Mounting and Distance

First, mount the IV4-400CA at a distance of at least 400 mm from the target. The narrow field of view suits small-part inspection where detail matters. Next, verify the field of view against the working distance using the reference values. Adjust the camera angle until the target fills the frame properly.

Wiring and Network Setup

Connect the M12 X-code Ethernet cable to the camera and the network switch. For PoE operation, confirm the switch supplies Power Class 4/6. Otherwise, wire the 24 VDC supply and I/O lines to the terminal. Finally, assign an IP address and select the protocol that matches the PLC.

Lighting and Filter Configuration

Choose pulse lighting for moving parts and continuous lighting for stationary targets. If reflections cause instability, install a compatible polarizing filter. Note that filter installation reduces the IP67 rating. Therefore, add extra shielding in wet or dusty areas.

FAQ

Q1: What field of view does the IV4-400CA provide?
A: At 400 mm it covers 58 x 44 mm. At 3000 mm it expands to 464 x 348 mm as a reference value.

Q2: Can this camera work without a separate controller?
A: Yes. The IV4-400CA has built-in AI processing, so it runs inspections standalone without a vision controller.

Q3: Which fieldbus protocols are supported?
A: EtherNet/IP, PROFINET CC-B, OPC UA, and MQTT work natively. The IV4-CU1 unit adds PROFINET CC-C and EtherCAT.

Q4: Does the IP67 rating apply with polarizing filters?
A: No. The IP67 rating does not apply when OP-88640, OP-88641, OP-88644, or OP-88645 filters are installed.

Q5: How do I ship this product?
A: We ship worldwide via Fedex, UPS, and DHL. Delivery times vary by destination.
