Basler ace 2 a2A5328-35cc

a2A5328-35cc

The a2A5328-35cc belongs to Basler's ace 2 V (CXP) family and uses the 1.2" Sony Pregius S IMX540 CMOS sensor with a 2.74 µm pixel size and global shutter, providing 5328 x 4608 px (24.4 MP) color images at up to 35 fps over a single CoaXPress 2.0 link (CXP-12, 2.5–12.5 Gbps). It uses a C-mount and an HD-BNC (Micro-BNC) data connector, and is powered via Power over CoaXPress (PoCXP) with typical consumption of about 4.1 W. The compact box housing measures 29 x 29 mm in cross-section, weighs under 85 g, carries an IP30 rating, and supports the CoaXPress 2.0 and GenICam standards. It is intended for high-resolution machine vision tasks such as inspection, measurement, and code reading.

Technical overview

The Basler ace 2 a2A5328-35cc pairs a 1.2-inch Sony Pregius S IMX540 global shutter CMOS sensor with a single CoaXPress 2.0 (CXP-12) link, and that combination is the heart of what it does. The sensor delivers 5328 x 4608 px (24.4 MP) of color detail from 2.74 x 2.74 um pixels, so an installer is buying genuine spatial resolution: at a working field of view of, say, 300 mm wide, each pixel still resolves on the order of 56 um, which is why this camera lands in Basler's high-resolution family and suits fine defect, measurement, and code-reading work. Because the shutter is global rather than rolling, every pixel is exposed simultaneously, so fast-moving parts on a conveyor or rotating fixtures are captured without the skew or smear that plagues rolling-shutter sensors. That makes it a clean fit for triggered, motion-coupled inspection rather than only static scenes.

The interface choice is what distinguishes this model from its GigE and USB cousins. A single CoaXPress 2.0 coax link runs at CXP-12 speed (up to 12.5 Gbps), which is what allows the full 24.4 MP frame to stream at 35 fps; that bandwidth headroom is precisely why the camera can sustain high resolution and respectable frame rate at the same time rather than trading one for the other. CoaXPress also carries power and trigger over the same cable via Power over CoaXPress (PoCXP), so the camera draws its ~4.1 W at 24 VDC from the frame grabber through the HD-BNC (Micro-BNC) connector, simplifying cabling to a single coax run. Practically, designing this camera in means budgeting for a CXP-12 frame grabber and the matching coax cabling, not a standard NIC or USB port.

Mechanically and optically the camera is built for tight, embedded installs. The housing is a compact 36.3 x 29 x 29 mm box weighing about 85 g, with a C-mount that accepts the broad ecosystem of standard machine-vision lenses; just confirm the lens covers the 1.2-inch (19.3 mm diagonal) format and resolves the 2.74 um pixel pitch, since an undersized or low-MP lens will throw away the sensor's resolution. The IP30 rating means it is protected against solid objects but not dust or liquids, so it expects an enclosure or clean cabinet rather than open washdown environments, and the -10 to 50 C operating range covers typical factory-floor conditions. Being a color model on a Bayer sensor, it is the right choice when print color, label verification, or material color matters; if the task is purely grayscale defect or metrology, a mono variant would give more effective resolution and light sensitivity. Pair it with bright, well-controlled strobe or continuous lighting and a hardware trigger into the grabber to lock exposure to part position.

Standards support is straightforward for integrators: the camera speaks CoaXPress 2.0 and GenICam, so it drops into any GenICam-compliant acquisition software and frame grabber without proprietary glue, and feature access (gain, exposure, ROI, trigger configuration) follows the standard register model.

Best for

  • High-resolution surface and defect inspection on moving lines where the global shutter freezes motion without smear at 35 fps full-frame
  • Dimensional measurement and metrology that needs the 24.4 MP (5328 x 4608) detail and fine 2.74 um pixel pitch over a wide field of view
  • Color-dependent tasks such as print, label, and packaging verification where the Bayer color sensor distinguishes hues a mono camera cannot
  • 1D/2D code reading and traceability on small or dense codes that benefit from high pixel count and the CXP bandwidth to read at speed
  • OCR/OCV of printed text on electronics, semiconductor, or automotive parts requiring crisp, distortion-free high-resolution capture

Selection notes

  • Plan the acquisition chain around CoaXPress: this is a CXP-12 camera that requires a CoaXPress 2.0 frame grabber and HD-BNC (Micro-BNC) coax cabling, not a GigE NIC or USB3 port; the same coax delivers PoCXP power (24 VDC, ~4.1 W), so no separate power supply is needed at the camera.
  • Match the lens to the sensor: choose C-mount optics that cover the 1.2-inch (19.3 mm diagonal) format and resolve the 2.74 um pixel pitch, otherwise the lens, not the sensor, becomes the resolution limiter.
  • Confirm full-frame throughput needs: 35 fps is at the full 5328 x 4608 resolution; if the application needs higher rates, plan to use a region of interest, since framerate typically scales with the reduced sensor area.
  • Account for the environment: IP30 protects against solid objects but not dust or liquids, so house the camera in a clean enclosure or cabinet; verify ambient stays within the -10 to 50 C operating range.
  • Decide color versus mono deliberately: this is a color model, ideal when color information is part of the inspection; if the task is pure grayscale defect detection or measurement, a monochrome variant yields more effective resolution and sensitivity for the same sensor.
