Basler ace 2 a2A2590-60ucBAS

a2A2590-60uc

The Basler a2A2590-60ucBAS is a USB 3.0 (USB3 Vision) industrial area scan camera in the ace 2 Basic line, built around a 1/2.8" Sony IMX334 progressive-scan CMOS color sensor with 2592 x 1944 resolution (5 MP) and 2.0 x 2.0 um pixels. It uses a rolling shutter and delivers up to roughly 60 fps in free-run, with selectable 8/10/12-bit pixel depth output over a USB 3.0 Micro-B interface. The camera is powered over USB (typ. ~2.9 W), uses a C-mount lens mount, weighs under 85 g, and carries an IP30 rating with an operating range of -10 to 60 C.

Technical overview

The Basler ace 2 a2A2590-60ucBAS is a 5 MP USB 3.0 area scan camera built around a 1/2.8" Sony IMX334 progressive-scan CMOS color sensor. Its 2592 x 1944 native resolution gives an installer roughly 5 million pixels per frame, and because the sensor diagonal is only 6.53 mm with very small 2.0 x 2.0 um pixels, you get high spatial detail in a physically compact optical format. That density is the camera's main story: it lets you resolve fine features (print, surface texture, small codes) over a modest field of view without moving to a large, expensive sensor. The trade-off to plan for is light hunger and lens demand, since 2 um pixels collect comparatively few photons each and need optics that can actually resolve at that pitch.

Image capture uses a rolling shutter rather than a global shutter, and the camera runs at up to roughly 60 fps in free-run over its USB 3.0 (USB3 Vision, 5 Gbit/s) interface. Sixty frames per second at full 5 MP resolution makes this a fast camera for inline inspection, but the rolling shutter means rows are exposed sequentially, so fast lateral motion can skew or smear. In practice that steers the design toward stationary or indexed parts, or toward freezing motion with a short exposure and bright, well-timed lighting (strobed illumination synchronized to the part). Pixel depth is selectable at 8/10/12 bits, so you can trade bandwidth for tonal range when fine grayscale gradients or color fidelity matter. As a single-sensor color CMOS model, it is suited to tasks where hue, label color, or print color is part of the inspection criterion rather than pure grayscale defect detection.

Mechanically and electrically the camera is built for easy design-in: a C-mount lens interface, a 48.1 x 29 x 29 mm housing, weight around 85 g, and power drawn directly over the USB 3.0 Micro-B connector (5 VDC, typ. ~2.9 W), so no separate power supply is required for a basic single-camera cell. It speaks USB3 Vision v1.0 and GenICam, so it drops into standard machine-vision software stacks. The IP30 rating and -10 to 60 C operating range indicate an enclosure-protected, indoor industrial deployment rather than a washdown or outdoor one; for dusty, wet, or splash environments you will need a protective housing. The C-mount and 1/2.8" format make lens selection straightforward, but the small pixels mean you should pair it with a lens of sufficient resolving power and choose magnification so that your smallest feature still lands on several pixels.

Best for

  • High-detail print and label inspection where color and fine text/graphics must be read at up to ~60 fps on indexed or slow-moving product
  • Industrial OCR/OCV and 2D code reading on packaging and components, using the 5 MP resolution to resolve small characters and code modules
  • Surface and cosmetic defect inspection on electronics and small parts where the dense 2 um pixel pitch captures fine texture over a compact field of view
  • Dimensional measurement and gauging of stationary or fixtured parts where full-resolution detail matters more than freezing rapid motion
  • Compact single-camera robot guidance or pick stations where USB-powered, lightweight (~85 g) integration with no extra power supply simplifies the cell

Selection notes

  • Confirm your motion profile suits a rolling shutter: parts that move quickly across the frame during exposure can skew or smear, so favor stationary, indexed, or strobe-frozen imaging, or step up to a global-shutter model if continuous high-speed motion is unavoidable
  • Budget for light: 2.0 um pixels and the small 1/2.8" sensor collect limited photons per pixel, so plan adequate, well-controlled illumination and reasonable exposure times to keep noise down at full 60 fps
  • Match the lens to the pixel pitch: use a C-mount lens with enough resolving power for ~2 um pixels and select magnification so the smallest target feature spans several pixels across your field of view
  • Verify USB 3.0 cabling and host capacity: the 5 Gbit/s USB3 Vision link supplies both data and the ~2.9 W of power over the Micro-B connector, so use a quality locking cable and ensure the host port/controller can sustain full-rate 5 MP streaming
  • Check the environment against IP30 and -10 to 60 C: this is an indoor, enclosure-protected camera, so add a protective housing for dust, moisture, or washdown areas, and use the selectable 8/10/12-bit depth to balance bandwidth against the tonal range your application needs
