Basler ace 2 a2A2048-37gc

a2A2048-37gc

The Basler a2A2048-37gc (model a2A2048-37gcBAS) is a 3.2 MP industrial area scan camera with a 2064 x 1552 pixel resolution on a 1/3.1" Sony IMX900 progressive-scan CMOS sensor featuring a global shutter and 2.25 µm pixels. It connects over Gigabit Ethernet (GigE Vision / GenICam) and reaches up to 37.2 fps at full resolution with optimized bandwidth settings. The color camera uses a C-mount, can be powered via PoE (IEEE 802.3af) or 12-24 VDC, and carries an IP30-rated box housing weighing under 100 g.

Technical overview

The Basler ace 2 a2A2048-37gc is a 3.2 MP color area scan camera built on the 1/3.1" Sony IMX900 progressive-scan CMOS sensor, delivering a 2064 x 1552 image through a true global shutter. The global shutter is the headline characteristic for an installer: every pixel is exposed simultaneously, so parts moving on a conveyor or indexing under the optics are captured without the skew and smear that a rolling shutter introduces. Paired with a frame rate of up to 37.2 fps at full resolution (32.6 fps in the default configuration), this makes the camera a sound choice for in-line inspection where the product never fully stops, and it removes the timing guesswork that otherwise forces you to gate motion to the sensor.

The sensor uses very small 2.25 x 2.25 µm pixels on a compact 5.81 mm diagonal (4.61 x 3.46 mm) optical format, which is what packs 3.2 MP into a 1/3.1" sensor. That density has direct optical consequences. To resolve detail at the pixel level you need a lens that out-resolves 2.25 µm pixels, so plan on a higher-grade C-mount lens corrected for a small format rather than an economy optic; the C-mount itself is standard and widely supported. The small pixel also means each photosite collects less light, so the camera rewards generous, controlled illumination. Because it is a color model with a Bayer pattern, it is the right pick when the inspection depends on hue (color-coded parts, print color verification, produce grading) and the wrong pick when you only need contrast, where a mono sensor would give more effective resolution and sensitivity for the same lens.

Connectivity and power are oriented toward simple, single-cable installs. The camera is GigE Vision / GenICam over Gigabit Ethernet (1000 Mbit/s), giving cable runs up to about 100 m on standard Ethernet without repeaters, which is far longer than USB3 reach and convenient for distributed cells. It can be powered over the same cable via PoE (IEEE 802.3af) or alternatively from 12-24 VDC, drawing only 3.7 W. The package is a lightweight box housing under 100 g (62.2 x 29 x 29 mm) rated IP30 and rated for -10 to 60 °C operation. IP30 means no liquid or fine-dust protection, so in washdown or dusty lines it must sit inside an enclosure. For triggered acquisition, pair it with a hardware trigger source (encoder or photoelectric sensor) and a strobed light synchronized to the global-shutter exposure so motion is frozen and lighting is repeatable shot to shot.

Best for

  • In-line defect and surface inspection of moving parts where the global shutter eliminates motion distortion at up to 37 fps
  • Color-dependent tasks such as print/label color verification, color-coded component checks, and food and beverage grading
  • Reading and verifying 1D/2D codes and printed text (OCR/OCV) for traceability on a conveyor
  • Distributed inspection cells needing long single-cable PoE runs over Gigabit Ethernet up to about 100 m
  • Compact, lightweight robot- or gantry-mounted vision where the sub-100 g box housing keeps payload low

Selection notes

  • The 2.25 µm pixels demand a high-resolution C-mount lens corrected for the small 1/3.1" (5.81 mm diagonal) format; an economy lens will be the limiting factor, not the sensor
  • Choose this color model only when hue matters; the Bayer filter trades effective resolution and light sensitivity versus a mono version, so prefer mono for pure contrast or measurement tasks
  • Small pixels collect less light, so budget for bright, controlled illumination and plan a strobed light synchronized to the global-shutter exposure for fast-moving lines
  • IP30 offers no dust or liquid ingress protection; specify a protective enclosure for washdown, oily, or dusty environments and stay within the -10 to 60 °C operating range
  • Confirm your network supports GigE Vision with a PoE (802.3af) switch or budget a 12-24 VDC supply; at 3.7 W the camera is easy to power either way, but reaching 37.2 fps requires the optimized-bandwidth setup rather than the 32.6 fps default
