The Basler a2A2464-23gm is a Gigabit Ethernet industrial area-scan camera in the ace 2 R family, built around the 5 MP (2448 x 2048) OmniVision OG05C back-illuminated global-shutter CMOS sensor with 3.45 µm pixels on a 2/3" optical format. It delivers up to 23 frames per second in monochrome with selectable 8/10/12-bit pixel depth over a GigE Vision 2.0 / GenICam interface. The C-mount camera is powered via PoE (IEEE 802.3af) or 12-24 VDC and provides one opto-coupled input and two configurable GPIO lines on an M8 6-pin connector. Its compact IP30 housing weighs under about 100 g and operates from -10 to 60 °C.
The Basler a2A2464-23gm sits in the ace 2 R family and is built around a 5 MP (2448 x 2048) OmniVision OG05C back-illuminated (BSI) global-shutter CMOS sensor on a 2/3" optical format. The global shutter is the defining trait here: every pixel is exposed simultaneously, so the camera freezes motion without the skew or smear a rolling shutter introduces. That makes it well suited to indexed conveyors, parts on a turntable, or robot-mounted inspection where the scene or the camera is moving during capture. With 3.45 micron pixels and back-illuminated construction, the sensor keeps reasonable light sensitivity at this resolution, which matters because smaller pixels collect less light and typically demand brighter, well-controlled illumination.
On the data side, the camera runs up to 23 fps in monochrome over a Gigabit Ethernet link using GigE Vision 2.0 and GenICam, with selectable 8/10/12-bit pixel depth. GigE makes switch-based multi-camera setups easy and lets the camera sit far from the controller, which is a practical advantage over USB3 when cable runs are long. The trade-off is that 23 fps is the ceiling at full 5 MP resolution; for a single inspection per part on a moderate-cadence line that is ample, but it is not a high-frame-rate camera for continuous fast motion. The 12-bit option is useful when you need fine grey-level discrimination for subtle surface or contrast defects, at the cost of more bandwidth per frame.
The monochrome sensor and C-mount complete the design-in picture. Mono delivers full per-pixel resolution and higher effective sensitivity than a Bayer-filtered color sensor, which is what you want for measurement, edge-based gauging, OCR/OCV, and code reading. C-mount is the standard interface for this sensor size, but the 2/3" format means you must pair it with a lens that covers a 2/3" image circle and resolves 3.45 micron pixels to actually realize the 5 MP detail. Power is flexible: PoE (IEEE 802.3af) lets you run a single cable for data and power, or you can use 12-24 VDC. The M8 6-pin connector carries one opto-coupled input plus two configurable GPIO lines for hardware triggering and strobe/light synchronization, and the compact sub-100 g IP30 housing rated -10 to 60 C is built for cabinet, gantry, and machine-frame mounting rather than washdown environments.
Best for
Motion-freezing inspection on indexed conveyors, turntables, or robot-mounted heads where the global shutter eliminates rolling-shutter distortion
OCR/OCV and 1D/2D code traceability where full monochrome resolution and 12-bit greyscale aid character and code contrast
Dimensional measurement and edge-based gauging that benefit from the sharp, distortion-free 2448 x 2048 mono frame
Surface and defect inspection in electronics, automotive, and semiconductor lines that need clean detail at moderate cadence
Multi-camera GigE installations where cameras sit far from the controller and single-cable PoE wiring reduces harnessing
Selection notes
Pair the C-mount with a lens that covers the 2/3" image circle and resolves 3.45 micron pixels; an under-spec lens will throw away the 5 MP detail you paid for.
23 fps is the full-resolution ceiling, so confirm your line cadence and per-part exposure budget fit within it; this is a moderate-speed, not high-frame-rate, camera.
The smaller 3.45 micron pixels and 5 MP mono sensor reward strong, controlled lighting; plan illumination and use the opto-coupled input plus two GPIO lines to hardware-trigger and strobe-synchronize the light.
Budget GigE bandwidth: moving from 8-bit to 10/12-bit at full 23 fps increases data per frame, so size the network link and any multi-camera switch accordingly.
The IP30 housing is for protected cabinet, gantry, or machine-frame mounting; specify external enclosures for dusty, wet, or washdown areas, and stay within the -10 to 60 C operating range.
Decide power early: PoE (802.3af) gives single-cable data-plus-power, while 12-24 VDC suits existing field wiring; the M8 6-pin connector handles I/O in both cases.

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.
Frequently asked questions
It is monochrome (mono). The OmniVision OG05C sensor captures greyscale at the full 2448 x 2048 resolution, which favors measurement, OCR/OCV, code reading, and contrast-based defect detection over color discrimination.
It uses Gigabit Ethernet with the GigE Vision 2.0 and GenICam standards and delivers up to 23 frames per second at full 5 MP resolution, with selectable 8/10/12-bit pixel depth.
Global shutter. All pixels are exposed at the same instant, so it freezes moving parts without the skew or smear typical of rolling-shutter sensors, making it suitable for moving conveyors and robot-mounted use.
It runs on PoE (IEEE 802.3af) over the Ethernet cable or on 12-24 VDC. An M8 6-pin connector provides one opto-coupled input and two configurable GPIO lines for triggering and light synchronization.
It has a C-mount and a 2/3" optical format sensor (about 11.09 mm diagonal) with 3.45 micron pixels, so it needs a C-mount lens that covers a 2/3" image circle and resolves to the pixel pitch.
Its housing is rated IP30 and it operates from -10 to 60 C, so it is intended for protected cabinet, gantry, or machine-frame mounting; wet, dusty, or washdown areas require an external protective enclosure.
