The boA4500-45cm belongs to Basler's boost series and pairs the onsemi XGS 20000 1.3" global shutter CMOS sensor (3.2 µm pixels, 20 MP) with a high-bandwidth CoaXPress 2.0 (CXP-12) interface transferring up to 12.5 Gbps per cable. It delivers 46 fps at full 20 MP resolution over a single coax cable and is powered via PoCXP or 24 VDC. The camera uses Basler's universal lens mount front (F-mount, M42x0.75 or M42x1 options purchased separately) and conforms to the GenICam and CoaXPress 2.0 standards with an IP30-rated box housing.
The Basler boost boA4500-45cm is a 20 MP monochrome area scan camera that pairs the onsemi XGS 20000 1.3-inch global shutter CMOS sensor with a CoaXPress 2.0 (CXP-12) interface. The 4500 x 4500 px square sensor measures 14.4 x 14.4 mm with 3.2 um pixels, which gives an installer a genuinely high-density, geometrically uniform image: the square format means a part can be presented in any rotation without wasting field of view, and the fine pixel pitch resolves small features for surface and defect work. Because the shutter is global, every pixel is exposed simultaneously, so fast-moving parts on a conveyor or indexer are captured without the skew that a rolling shutter introduces, making this camera suited to flash-illuminated, motion-stop or continuous-motion inspection.
The headline capability is throughput. The XGS 20000 delivers up to 46 fps at full 20 MP over a single coax cable thanks to the CXP-12 link, which carries up to 12.5 Gbps. For an installer this collapses cabling and connector count compared with multi-cable high-speed interfaces, while still moving 20 MP frames fast enough for high-line-rate stations. CoaXPress also supplies Power-over-Coax (PoCXP), so the camera and trigger/data path can run on one cable; alternatively it accepts 24 VDC (18.6 to 26 VDC) at roughly 9.7 W typical. Note that CXP-12 requires a dedicated CoaXPress frame grabber in the host PC, not a standard network or USB port, so the host and cabling must be specified around that interface and its 75-ohm coax.
Optically and mechanically, the camera uses Basler's universal front that accepts F-mount, M42x0.75 or M42x1 lenses (purchased separately), so the lens must cover the 1.3-inch / 20.36 mm-diagonal sensor and resolve the 3.2 um pixels to realize the full resolution. The unit is a box-style housing measuring 49.1 x 80 x 80 mm and weighing 525 g, rated for 0 to 50 C operation, and it conforms to the GenICam and CoaXPress 2.0 standards for standardized configuration and software integration. As a monochrome sensor it maximizes light sensitivity and detail per pixel and pairs naturally with controlled monochromatic or strobed illumination for contrast-critical tasks; it does not provide color discrimination.
Best for
High-resolution surface and defect inspection on electronics, semiconductor and printed parts where 20 MP at 3.2 um pixels resolves fine flaws
High-speed inspection lines that need full 20 MP frames at up to 46 fps without rolling-shutter distortion on moving parts
Dimensional measurement and metrology that benefits from the square 4500 x 4500 px field and uniform global-shutter capture
Industrial OCR/OCV reading of small printed or marked text where monochrome detail and resolution matter
Single-cable high-bandwidth deployments using CoaXPress CXP-12 with PoCXP to simplify camera wiring at the station
Selection notes
Requires a CoaXPress 2.0 (CXP-12) frame grabber and 75-ohm coax in the host PC; this is not a GigE/USB plug-in camera, so budget for the grabber and cabling.
Lens is sold separately and must cover the 1.3-inch (20.36 mm diagonal) sensor and resolve 3.2 um pixels; choose F-mount, M42x0.75 or M42x1 accordingly to avoid limiting effective resolution.
Plan power as either PoCXP over the single coax or external 24 VDC (18.6 to 26 VDC, ~9.7 W typ.); confirm the grabber supplies sufficient PoCXP if running cable power only.
Monochrome only: pair with controlled or strobed illumination and select wavelength/geometry for the task, since the camera provides no color information.
Account for the 80 x 80 mm box footprint, 525 g weight and 0 to 50 C operating range when designing the mount and thermal environment; verify any IP/sealing requirement as the housing protection rating is not confirmed by the primary source.

Get a first image quickly with the pylon Viewer, then move into the pylon SDK for your application. These cameras are GenICam/GenTL-compliant, so any compliant vision software can drive them as well.
Download and install the pylon Camera Software Suite for your OS from Basler. This provides the pylon Viewer, the GenTL transport-layer producers and the pylon SDK (C/C++/.NET/Python). On Windows the installer adds the needed drivers; on Linux follow the included setup notes for USB and network permissions.
2. Connect the camera and check the link
Cable the camera to its matching interface: GigE Vision to a GigE port (use a quality cable and, ideally, a dedicated NIC with jumbo frames enabled), USB3 Vision to a USB 3.x port with the supplied cable, or CoaXPress to the frame grabber. Provide power where required (PoE, USB bus power, or PoCXP). Open the pylon Viewer and confirm the camera appears in the device list; for GigE, make sure the camera and NIC are on the same subnet.
3. Grab a first image and set exposure, gain and pixel format
Select the camera in the pylon Viewer and start a continuous grab. Adjust exposure time and gain until the image is well exposed (avoid clipped highlights), set the pixel format (e.g. Mono8 or a Bayer/RGB format), and focus the lens. Use a test pattern if the lens or scene is not ready yet.
4. Configure triggering and acquisition
Decide between free-run and triggered acquisition. For synchronized capture, set the trigger source (software or a hardware line on the I/O connector), trigger mode and any debounce or exposure mode, then verify timing. Note the parameter names you change in the Viewer feature tree, as you will reuse them in code.
5. Move to the SDK or a GenICam-compliant library
Recreate your settings in code with the pylon SDK (C, C++, .NET or Python) to open the device, apply the same features and pull frames into your pipeline; pylon vTools and pylon AI can add processing blocks. Because the cameras are GenICam/GenTL standard, third-party vision libraries work too. Once the image stream is stable, you can route frames to a deep-learning inspection such as Rosepetal for automated defect detection.
