Basler ace 2 a2A5328-22g5cBAS

a2A5328-22g5cBAS

The Basler ace 2 a2A5328-22g5cBAS is a high-resolution 5GigE area scan camera featuring the Sony IMX540 progressive scan CMOS sensor with a 5328 x 4608 pixel resolution (24.4 MP) and 2.74 µm pixel pitch. It employs global shutter technology for distortion-free imaging of moving objects and supports multi-speed Ethernet connectivity (100 Mbps, 1G, 2.5G, and 5G). The camera conforms to GigE Vision 2.0 and GenICam standards, outputs 8/10/12-bit pixel depth, and provides an IP30-rated housing operating from -10 °C to 50 °C. It is powered via an external 12–24 VDC supply and uses a C-mount lens interface.

Technical overview

The Basler ace 2 a2A5328-22g5cBAS is built around the Sony IMX540-AAQJ-C Pregius S sensor, a global-shutter CMOS device delivering 5328 x 4608 pixels (24.4 MP) at a 2.74 µm pixel pitch across a 1.2" optical format (14.57 mm × 12.6 mm active area, 19.26 mm diagonal). Global shutter means every pixel integrates simultaneously, so there is no row-skew or motion artifact on fast-moving parts or strobe-lit conveyor lines — a property that matters critically in surface inspection and dimensional measurement where a rolling-shutter smear could register as a defect or distort a caliper measurement. At full resolution the camera runs at 21.8 fps in default mode and 23.5 fps in Performance mode, giving throughput adequate for most in-line inspection cells while the 24.4 MP frame delivers sub-pixel spatial margin for high-accuracy gauging tasks. The 2.74 µm pixel pitch is the densest available in the Pregius S family and, when paired with a suitably corrected C-mount lens covering the 1.2" image circle, yields a field-of-view-to-resolution ratio that can resolve fine-pitch features — PCB trace width, pharmaceutical blister text, or automotive sealing surface — without stitching or multi-camera tiling.

Connectivity is handled via 5GigE (5GBASE-T), with backward compatibility across 100 Mbps, 1 G, and 2.5 G Ethernet infrastructure. This means the camera can be commissioned immediately on a standard GigE switch for evaluation and then migrated to a 5 G switch or NIC for production-rate transfer of the full-resolution data stream at 22 fps. The camera conforms to GigE Vision 2.0 and GenICam standards, so it integrates with any compliant SDK — Basler pylon, Halcon, Cognex VisionPro, or open-source libraries — without vendor lock-in. Pixel depth is selectable at 8, 10, or 12 bits per channel; 12-bit acquisition preserves the full dynamic range of the sensor and is advisable for surface-gloss inspection or gradient-sensitive defect algorithms, while 8-bit reduces bandwidth for code-reading or presence/absence tasks. Power arrives via an M8 6-pin connector at 12–24 VDC, drawing 6.3 W — manageable on standard DIN-rail power supplies without a dedicated high-current feed. The IP30-rated housing operates from -10 °C to +50 °C, covering most factory-floor temperature envelopes, though it requires enclosure protection in wet, dust-heavy, or chemical-wash environments.

The camera occupies the standard 29 mm × 29 mm ace 2 footprint (55.5 mm body depth, 105 g) and uses a C-mount lens interface. Because the sensor diagonal is 19.26 mm, installers must verify that the chosen C-mount lens covers 1.2" — a non-trivial selection point, since many cost-effective C-mount lenses are rated for 4/3" (21.6 mm) or 1.1" (17.6 mm) and will vignette on this sensor. Lenses designed for the 1.2" or larger format and corrected for 2.74 µm pixel pitch (resolving ≥180 lp/mm) are required to avoid resolution loss at the sensor periphery. For trigger-synchronised acquisition the camera accepts external hardware triggers; pairing with a pulsed LED strobe controller eliminates motion blur entirely and allows integration times short enough to freeze even high-speed mechanisms while the global shutter eliminates intra-frame distortion. The color variant includes an IR-cut filter, making spectral response accurate in the visible range for appearance inspection, color sorting, or label verification — tasks where accurate hue discrimination matters.

Best for

  • High-resolution surface and cosmetic inspection of large panels, PCBs, or automotive body components where 24.4 MP eliminates camera tiling and the global shutter prevents motion-induced pseudo-defects at line speed.
  • Dimensional gauging and metrology applications requiring sub-pixel accuracy across wide fields — the 5328 × 4608 pixel array provides spatial oversampling for edge-detection algorithms on parts up to several hundred millimetres wide without sacrificing measurement confidence.
  • Pharmaceutical and medical-device line inspection including blister pack verification, label OCR/OCV, and tamper-evidence checks, where the combination of high pixel count, selectable 12-bit depth, and color fidelity supports both appearance and character-level analysis in a single camera.
  • Packaging and traceability tasks — 2D code reading (Data Matrix, QR), label print inspection, and date-code verification — where the high pixel density ensures adequate sampling of small codes even at generous working distances, and the color sensor distinguishes label color variants.
  • Electronics and semiconductor in-line inspection of populated boards, wafer maps, or connector housings where 2.74 µm pixel pitch and global shutter together capture fine-pitch features on moving fixtures without artifact.

Selection notes

  • Lens image-circle coverage is the most common design-in pitfall: the Sony IMX540 sensor has a 19.26 mm diagonal (1.2" format), so the C-mount lens must be rated for 1.2" or larger and specified at ≥180 lp/mm centre resolution to fully exploit 2.74 µm pixels — lenses rated for 1.1" or 4/3" may vignette or soften corners.
  • NIC and switch selection must support 5GBASE-T to sustain full-frame throughput at 22 fps in 8-bit; at lower Ethernet tiers (1 G or 2.5 G) the host software must either reduce frame rate, apply ROI, or accept packet loss — plan the network infrastructure before commissioning.
  • The IP30 rating provides only basic finger/tool ingress protection with no liquid or dust sealing; applications in wash-down, high-particulate, or outdoor environments require an external sealed enclosure or consideration of a higher-IP-rated camera platform.
  • Power must be supplied externally at 12–24 VDC via an M8 6-pin connector; the camera does not support Power over Ethernet (PoE), so cable routing and DIN-rail power supply capacity (6.3 W per camera) must be budgeted separately from the GigE data cable.
  • Color mode with IR-cut filter is appropriate for appearance, color sorting, and OCR applications; applications that benefit from near-infrared illumination (e.g., silicon wafer inspection under 850 nm, print-through detection) require the monochrome variant of this model rather than this color version.
