Basler ace 2 a2A2590-22gcBAS

a2A2590-22gc

The Basler a2A2590-22gcBAS is an industrial area scan camera built around a 1/2.8" Sony IMX334 (IMX334ROI) progressive-scan CMOS sensor delivering 2592 x 1944 (5 MP) color images with a rolling shutter and 2.0 x 2.0 um pixels. It connects over Gigabit Ethernet (GigE Vision 2.0 / GenICam) and reaches 22 fps at full resolution. Power is supplied via PoE (IEEE 802.3af) or 12-24 VDC through the I/O connector, with typical consumption around 2.7-3.8 W. The camera uses a C-mount, weighs under 100 g, carries an IP30 rating, and supports Basler pylon software on Windows, Linux, macOS, and Android.

Technical overview

The Basler ace 2 a2A2590-22gcBAS is a GigE Vision area scan camera built around a 1/2.8-inch Sony IMX334 CMOS sensor, delivering 2592 x 1944 pixels (5 MP) of color image data at up to 22 fps in performance mode (20.4 fps default). The optical format measures 5.2 x 3.9 mm with a 6.5 mm diagonal, and the small 2.0 x 2.0 um pixels pack that 5 MP into a compact die. This combination suits inspection tasks that need a moderate amount of detail across a field of view without stepping up to a large-format, large-pixel sensor: surface and defect inspection, packaging checks, label and print verification, and reading printed or marked codes are all squarely in range. Color output means the camera can resolve features that depend on hue rather than contrast alone, which is the difference-maker for packaging artwork, color-coded components, and product appearance.

Two factors define how you stage this camera in a line. First, the shutter is rolling rather than global, so the IMX334 reads its rows sequentially. That is well matched to stationary or slow, steadily indexed parts under continuous light, but fast lateral motion or a moving conveyor can introduce skew or smear, so plan to freeze motion with a bright strobe or gate the part to a stop at the inspection station. Second, the interface is Gigabit Ethernet running GigE Vision 2.0 with GenICam, which gives you cable runs up to roughly 100 m on standard Ethernet, native multi-camera bandwidth budgeting on a switch, and PoE single-cable power and data. At 5 MP color and 22 fps the camera is comfortably within a single GigE link's bandwidth, so you get the long-reach, low-cabling-cost advantages of GigE without contending for throughput.

The mechanical and power story is built for easy integration. The camera carries a C-mount, accepts standard machine-vision lenses, and at 48.9 x 29 x 29 mm and about 100 g it drops into tight enclosures and lightweight robot-mounted setups; the listed application set includes robot guidance, where that low mass matters on a moving arm. Power comes either from PoE (IEEE 802.3af) for a single-cable install or from 12-24 VDC through the I/O connector when you already have field power, with typical draw around 2.7-3.8 W, so thermal load and supply sizing are modest. The IP30 rating means it is a clean-environment, in-cabinet or guarded-station device rather than a washdown unit; if the location sees dust, moisture, or spray you will need an enclosure. Basler's pylon SDK supports Windows, Linux, macOS, and Android, which keeps host-side options open from a PC controller down to an embedded or ARM platform.

Best for

  • Color surface and defect inspection of stationary or slowly indexed parts where 5 MP detail across the field of view is sufficient
  • Packaging and label inspection that depends on color artwork, print quality, and correct content
  • Reading and verifying printed or marked codes (OCR/OCV and traceability) on presented parts under controlled light
  • Multi-camera GigE installations needing long cable runs (up to ~100 m) and single-cable PoE power and data
  • Lightweight robot-mounted or space-constrained inspection cells where the ~100 g, 49 mm body and low ~3.8 W draw are advantages

Selection notes

  • Confirm the rolling shutter fits your motion profile: it is ideal for static or steadily indexed parts, but fast conveyor motion can cause skew, so freeze the part with a strobe or stop it at the station
  • Budget your optics around the 1/2.8-inch (6.5 mm diagonal) format and 2.0 um pixels: pick a C-mount lens that covers the sensor and resolves fine enough to use the full 5 MP, since small pixels demand a sharp lens
  • Plan lighting for color: as a color camera with a Bayer sensor and small pixels, it benefits from bright, even, broadband illumination to keep exposure short and signal clean
  • Decide your power path early: PoE (802.3af) gives a one-cable install but requires a PoE switch or injector; otherwise wire 12-24 VDC to the I/O connector
  • Treat IP30 as a clean-environment rating: for dusty, wet, or washdown lines, add a protective enclosure rather than relying on the bare camera
