Basler ace 2 V a2A2448-120cm

a2A2448-120cm

The a2A2448-120cm is part of the Basler ace 2 V series and uses a 1/1.8" Sony IMX547 Pregius S CMOS global shutter sensor with 2448 x 2048 effective resolution (5 MP) and 2.74 µm square pixels. It connects via a single CoaXPress 2.0 link (2.5-12.5 Gbps) and reaches 122.8 fps at CXP-12/CXP-10, supporting 8/10/12-bit output. The camera is housed in a compact 50.2 x 29 x 29 mm box body, uses a C-mount, and is powered over CoaXPress (PoCXP, 24 VDC) at about 3.1 W typical. It complies with GenICam and CoaXPress 2.0 standards and carries an IP30 protection rating.

Technical overview

The Basler ace 2 V a2A2448-120cm is a 5 MP monochrome area scan camera built around the 1/1.8" Sony IMX547 Pregius S CMOS sensor (IMX547-AAMJ-C), a global shutter device with 2448 x 2048 effective pixels on a 2.74 µm square pitch. The global shutter is the headline attribute for any installer: every pixel is exposed simultaneously, so parts moving on a conveyor, indexing on a turntable, or imaged under a strobe arrive geometrically undistorted with no rolling-shutter skew. At 2.74 µm pixels the sensor strikes a deliberate balance between resolution and sensitivity, and the small 1/1.8" optical format (6.71 x 5.61 mm, 8.8 mm diagonal) keeps lens cost and size down while still demanding a lens that resolves down to that fine pitch. As a monochrome camera it captures full luminance at every pixel without a Bayer filter, which is what you want for dimensional gauging, edge metrology, presence/absence and most surface-defect work where color is not the discriminator.

The defining system characteristic is the interface: this is a CoaXPress 2.0 camera using a single CXP-12 coax link rated 2.5 to 12.5 Gbps, and it sustains 122.8 fps at full 5 MP resolution under CXP-12 or CXP-10. That throughput class is what separates a CoaXPress design from a GigE or USB3 one. You get long, low-cost coaxial cabling, deterministic low-latency triggering, and bandwidth that holds full frame rate where USB3 or GigE would force you to crop or drop frames. Output is selectable at 8, 10, or 12 bit, so you can trade bandwidth for the extra grayscale depth that surface and contrast-limited inspection benefit from. The camera is GenICam-compliant and follows the CoaXPress 2.0 standard, so it integrates with any compliant CXP frame grabber and standard GenICam software stack rather than a proprietary SDK lock-in.

Mechanically and electrically the camera is built for dense, fixed-mount machine-vision cells. It is a compact 50.2 x 29 x 29 mm box body weighing 85 g, takes a standard C-mount lens, and draws only about 3.1 W typical, powered directly over the coax via Power over CoaXPress (PoCXP, 24 VDC) so a single cable carries power, data, and trigger. Operating range is -10 to 50 °C, and the housing carries an IP30 rating, meaning it is protected against solid objects but not against dust ingress or liquids, so it expects an enclosed cabinet or a protective housing in dirty environments. For the installer this is a single-cable, low-power, small-footprint sensor head that pairs naturally with strobed or continuous illumination and a hardware trigger fed through the CoaXPress link for tightly synchronized, motion-frozen capture.

Best for

  • High-speed inline inspection where parts move continuously and the 122.8 fps full-resolution rate plus global shutter freeze motion without blur or skew
  • Surface and defect inspection on electronics, semiconductor, and battery components where 5 MP monochrome detail and 8/10/12-bit grayscale depth resolve fine flaws
  • Dimensional measurement and edge metrology that needs distortion-free global-shutter geometry across the full 2448 x 2048 frame
  • Industrial OCR/OCV and code-mark reading where crisp monochrome contrast and high frame rate keep up with fast indexing lines
  • CoaXPress-based multi-camera cells that need long, low-cost coax runs and deterministic PoCXP single-cable power-data-trigger wiring

Selection notes

  • This is a CoaXPress 2.0 / CXP-12 camera, so it requires a matching CXP frame grabber and PoCXP-capable host; it is not a plug-and-network GigE or USB3 device and budgets must include the grabber and coax cabling.
  • Confirm your lens resolves the 2.74 µm pixel pitch over the 1/1.8" (8.8 mm diagonal) format; an under-resolving C-mount lens will cap effective resolution below the sensor's 5 MP capability.
  • The IP30 rating protects only against solid objects, not dust or liquids, so plan an enclosure or protective housing for washdown, dusty, or splash-prone lines and keep within the -10 to 50 °C operating window.
  • Monochrome only: if the application depends on color discrimination this camera is the wrong choice; for grayscale defect, gauging, and code work it is well matched.
  • At full 5 MP and 122.8 fps the link runs near CXP-12 bandwidth; choose 8, 10, or 12-bit output deliberately, since higher bit depth and any ROI/binning choices trade directly against achievable frame rate.
