Basler ace 2 a2A5328-4gcBAS

a2A5328-4gc

The Basler ace 2 a2A5328-4gc is a high-resolution GigE Vision area-scan camera from the ace 2 R series, using a 1.2" Sony Pregius S IMX540 global-shutter CMOS sensor with 24.4 MP resolution (5328 x 4608 px) and 2.74 um pixels. It outputs color images at up to 4 fps with selectable 8/10/12-bit pixel depth and a 70.8 dB dynamic range over a Gigabit Ethernet (GigE Vision 2.0 / GenICam) interface. The compact 55.5 x 29 x 29 mm housing offers a C-mount, RJ45 data plus M8 6-pin I/O connectors, and can be powered via PoE or 12-24 VDC at about 3 W. It carries an IP30 rating and operates from -10 to 60 degrees C.

Technical overview

The Basler ace 2 a2A5328-4gc is a 24.4 MP color area-scan camera built on the 1.2-inch Sony Pregius S IMX540 global-shutter CMOS sensor, resolving 5328 x 4608 px across a 14.57 x 12.6 mm imaging area. The defining trade-off here is resolution density against speed: with 2.74 um pixels and a full-frame readout, the camera delivers 4 fps at full resolution over its Gigabit Ethernet link. That makes it a deliberate fit for inspection tasks where spatial detail matters far more than frame rate, parts that are stationary or stepped into position rather than moving continuously past the lens. The global shutter is the second key property: it exposes every pixel simultaneously, so even when the camera triggers on an indexed part the captured frame is free of the motion skew a rolling shutter would introduce, which is what allows this sensor to be used for precise dimensional and edge-based work.

The interface is GigE Vision 2.0 over standard Gigabit Ethernet, speaking GenICam so it drops into Basler pylon and any compliant third-party vision software without custom drivers. Gigabit Ethernet sets a practical ceiling that explains the 4 fps figure: a 24.4 MP frame is a large payload, and the link bandwidth is the gating factor, not the sensor. The upside is reach and simplicity, cable runs up to 100 m and a single RJ45 carrying data, while power arrives either over PoE on that same cable or via the 12-24 VDC supply, drawing only about 3 W. The M8 6-pin connector breaks out the I/O lines you use to hardware-trigger the camera and synchronize a strobe, which is how you pair it cleanly with external lighting. Pixel depth is selectable at 8, 10, or 12 bits, and the sensor offers 70.8 dB of dynamic range, giving headroom for scenes with bright specular highlights alongside shadowed detail.

Mechanically this is a compact, lightweight unit: a 55.5 x 29 x 29 mm housing weighing 100 g with a C-mount and an IP30 rating, intended for enclosed cabinets and fixtures rather than open washdown environments. The C-mount and the 1.2-inch 19.26 mm-diagonal format are the critical numbers for the optical design, because the lens must cover that large image circle and resolve the 2.74 um pixels, so a high-resolution C-mount lens rated for the sensor format is essential to extract the full 24.4 MP. As a color camera it carries a Bayer filter, well suited to print, packaging, and surface tasks where color is the discriminating feature, at the usual cost of some luminance resolution versus a monochrome equivalent. The -10 to 60 deg C operating range covers typical factory-floor and enclosure conditions.

Best for

  • High-resolution surface and defect inspection on electronics, semiconductor, and automotive parts where the 24.4 MP frame resolves fine features across a wide field of view in a single capture
  • Dimensional measurement and metrology on stationary or indexed parts, where the global shutter and 2.74 um pixels support precise, distortion-free edge detection
  • Print and packaging inspection where color is the discriminating feature, leveraging the Bayer color sensor and selectable 8/10/12-bit depth
  • Industrial OCR/OCV and code reading on large or densely printed surfaces that benefit from high pixel count rather than high frame rate
  • Distributed multi-camera cells where the GigE Vision interface and PoE allow single-cable runs up to 100 m back to the controller

Selection notes

  • Plan the bandwidth budget: at 24.4 MP the Gigabit Ethernet link caps full-frame output at 4 fps, so this camera suits stepped or stationary inspection, not continuous high-speed flow; if you need more frames, a smaller ROI is the lever, not faster moving parts
  • Specify the lens deliberately: the 1.2-inch optical format (19.26 mm diagonal) and 2.74 um pixels demand a high-resolution C-mount lens that covers the image circle, otherwise you will not realize the full 24.4 MP
  • Confirm your host NIC and switch support GigE Vision 2.0 with jumbo frames, and provision PoE or a 12-24 VDC supply; the camera itself only draws about 3 W
  • Use the M8 6-pin I/O lines to hardware-trigger the camera and synchronize lighting; pairing a strobe with the global shutter freezes indexed parts cleanly and lets you control exposure timing
  • Note the IP30 rating: this housing is for cabinets and protected fixtures, not washdown or dusty open-air mounting, so add enclosure protection if the environment demands it
