Description
Product Overview
The Basler A402kc is a color industrial area-scan camera from the A400k family, developed for machine vision systems that require detailed image acquisition and predictable camera-to-frame-grabber communication. Its Aptina MT9M440 CMOS sensor provides 2352 × 1726 pixels, equivalent to approximately 4.06 megapixels. With a full-resolution frame rate of up to 24 fps, the camera is suitable for inspection stations, product identification, dimensional evaluation, and image-based process monitoring where color information is required. The sensor has a 7.0 μm pixel pitch and a 16.46 × 12.08 mm imaging area.
Image data is transferred through a Camera Link LVDS base-configuration interface using two data taps. The camera supports selectable 8-bit and 10-bit output, with documented net data rates of 99.3 MB/s at 8-bit depth and 124.1 MB/s at 10-bit depth. Exposure can operate in free-run mode or be controlled through an external ExSync signal. Additional image-control functions include programmable gain and offset, area-of-interest settings, shading correction, and configurable exposure timing. These functions allow engineers to adjust image acquisition to suit different inspection conditions without changing the camera hardware.
The Basler A402kc requires a 12 VDC supply and has a maximum power consumption of 8.5 W according to the manufacturer’s A400k manual. Its standard connections include a 26-pin MDR data connector, a 6-pin Hirose power connector, and a 4-pin Hirose flash-trigger connector. For replacement work, the Camera Link frame grabber, cable pinout, lens mount, camera version ID, and acquisition software configuration must be checked together. A camera with the same resolution but a different interface or tap configuration may not operate with the existing inspection system.
Product Introduction (Non-Templated)
A machine vision system can lose measurement consistency when a replacement camera changes sensor characteristics, output timing, or frame-grabber compatibility. The A402kc combines a 4.06-megapixel color sensor with a Camera Link base interface and programmable image-acquisition settings.
Before replacement, verify the original camera version, frame-grabber configuration, lens mount, and image-processing software. Matching the model designation alone is not enough if the surrounding acquisition hardware has been modified.

These models belong to the Basler A400k camera family. Their frame rates and interface configurations differ, so they should not be treated as automatic replacements.
- A402k – Monochrome version of the A402kc, with the same 2352 × 1726 sensor resolution and 24 fps full-resolution rate.
- A403kc – Color A400k camera with a higher 48 fps full-resolution rate and Camera Link medium configuration.
- A404kc – Color A400k camera with a documented 96 fps full-resolution mode using an 8-tap configuration.
- A405kc – Higher-speed color model rated at up to 167 fps, using a different Camera Link output configuration.
- A406kc – Higher-speed color model rated at up to 209 fps, using a Basler-specific 10-tap interface configuration.
Frequently Asked Questions
Q1: What is the Basler A402kc used for?
It is a color industrial area-scan camera used in machine vision applications such as product inspection, image-based measurement, component identification, and automated quality control.
Q2: What is the image resolution of the A402kc?
The camera provides 2352 × 1726 pixels, totaling approximately 4.06 megapixels. Its full-resolution frame rate is up to 24 fps.
Q3: Can I hot-swap this camera?
No. The manufacturer’s manual instructs users to switch off system power before connecting or disconnecting the camera. Disconnecting the camera while powered can damage it.
Q4: Does this support firmware v3.1?
A specific firmware v3.1 compatibility statement has not been verified. The camera is configured through Basler’s Camera Configuration Tool Plus and serial register commands. Confirm the camera version ID and software compatibility with the installed frame grabber.
Q5: Is the A402kc compatible with the A402k monochrome version?
They share the same general A400k architecture and resolution, but the A402kc is the color version while the A402k is monochrome. Replacing one with the other can affect image processing, color calibration, and inspection software.
Q6: Can I use a GigE or USB cable with the A402kc?
The documented data interface is Camera Link LVDS, not native GigE Vision or USB 3.0. A compatible Camera Link frame grabber and cable are required.
Q7: What should I inspect before purchasing a replacement?
Check the camera label, serial number, camera version ID, sensor surface, lens mount, connectors, and frame-grabber compatibility. For used units, request a live image test, dead-pixel inspection, and confirmation that the camera can acquire images at the expected resolution and frame rate.
Procurement recommendation: Specify Basler A402kc, not just A402K. The lowercase c identifies the color version. Confirm the Camera Link base configuration, 12 VDC supply, and existing frame-grabber compatibility before approving a replacement.
