High-resolution area scan camera built on the 1.1" Gpixel GMAX0505 global shutter CMOS sensor with 5120 x 5120 resolution and 2.5 um pixels. Camera Link interface (80-bit / Full / Medium / Base, CL 2.1) at up to 30.7 fps. C-mount, powered via PoCL or external +12 Vdc.
The Omron Sentech STC-GPB250BPCL is a 25 MP monochrome area scan camera built on a 1.1" Gpixel GMAX0505 global shutter sensor. The 5120 px horizontal resolution and 2.5 um pixels make it a high-resolution sensor that resolves fine detail across a large field of view in a single exposure. Because it is monochrome, every pixel contributes directly to luminance detail without a colour filter array, which typically improves effective spatial resolution and light sensitivity for measurement, defect and character-reading tasks where colour is not the discriminating feature.
The global shutter exposes the entire frame simultaneously, so the camera captures geometrically faithful images of moving parts without the skew or smear associated with rolling-shutter readout. Combined with a frame rate of up to 30.7 fps, this suits inline inspection where parts move continuously or index quickly and dimensional accuracy must be preserved. The 1.1" optical format and small 2.5 um pixels concentrate a large pixel count onto a moderate sensor area, demanding lenses that can resolve at that pitch and cover the format.
Connectivity is over Camera Link, a deterministic, low-latency parallel interface well suited to sustaining the high pixel throughput of a 25 MP sensor at speed, with a dedicated frame grabber handling acquisition. The camera supports Power over Camera Link (PoCL) and conforms to GenICam for standardised configuration and integration. A C-mount lens interface keeps it compatible with a wide range of standard industrial optics, subject to the lens supporting the sensor format and resolution.
Best for
High-precision dimensional measurement and metrology where a large pixel count over a wide field of view improves measurement resolution
AI-based surface defect inspection requiring fine detail and geometrically accurate frames of moving product
Industrial OCR/OCV for reading printed, embossed or marked characters at high resolution
Inline inspection of fast-moving or indexed parts where global shutter prevents motion distortion
Applications needing a single high-resolution snapshot to cover a large area and reduce the number of cameras or imaging stations
Selection notes
Pair with a high-resolution C-mount lens rated to resolve 2.5 um pixels and cover the 1.1" format; a lens that under-resolves the sensor will waste the available pixel count and soften measurement accuracy.
Plan the imaging chain around Camera Link: you need a compatible frame grabber and correctly rated Camera Link cabling, with PoCL or an external supply to power the camera per the chosen configuration.
Provide ample, stable illumination. Small pixels and short exposures at higher frame rates reduce the light gathered per pixel, so adequate lighting and exposure budgeting are important for low-noise images.
If your application needs colour discrimination, choose a colour variant instead, as this is a monochrome model. If a simpler standalone interface or longer cable runs are required, weigh a different interface against the Camera Link grabber-based architecture.
Confirm bandwidth and frame-grabber configuration support the resolution and frame rate you need, since sustaining full-resolution throughput depends on the Camera Link mode and grabber capability.

Applications this camera is commonly selected for. Open one to see the full recommended hardware and approach.
These steps take an Omron Sentech (STC) camera from the box to a stable first image and on to your own application. They apply across the GigE Vision, USB3 Vision and CoaXPress STC families; the interface only changes how you cable and power the camera.
Download and install the Sentech SDK on the host PC. The package provides StViewer, the viewing and configuration software you use to bring the camera up, and StApi, the programming SDK you integrate later. Because the cameras are GenICam/GenTL-compliant, StApi also registers a GenTL producer, so any GenICam-compliant third-party vision software can discover and drive the camera as an alternative front end.
2. Cable, power and connect the camera
Connect according to the interface. GigE Vision: link to a Gigabit NIC (use PoE or the separate power input) and put the camera and host on the same subnet; for USB3 Vision use a USB 3.x port and a certified cable; for CoaXPress (STC) connect to a CoaXPress frame grabber, which also supplies Power-over-Coax. Then open StViewer and let it enumerate the camera. If a GigE camera does not appear, check the IP configuration and firewall, and on USB3 confirm the host bandwidth and driver.
3. Configure exposure, gain and white balance
Open the device in StViewer and start a live stream. Set exposure and gain for a well-exposed, low-noise image: raise exposure first and only add gain when more light or a faster shutter is not an option, keeping exposure short enough to freeze motion on global-shutter models. On colour cameras, run white balance under your actual production lighting. Adjust the lens aperture and focus on a representative target before tuning anything else.
4. Set the trigger and grab a first image
Start in free-run (continuous) acquisition to confirm a clean, stable image. For inline inspection switch to hardware or software triggering: select the trigger source, set the active edge and any delay, and wire the strobe or illumination to the camera's I/O so lighting fires with each exposure. Acquire and save a frame in StViewer; this saved image is your reference for the SDK stage and for downstream inspection.
5. Move to the StApi SDK (or any GenICam software)
Once the image is stable, reproduce the same settings in code. Use StApi to open the device, apply the GenICam features you validated in StViewer (exposure, gain, trigger, pixel format) and grab frames into your application via the bundled C++, C, C#/.NET or Python interfaces; the included samples are the fastest starting point. Prefer a different stack? The same GenICam/GenTL camera works with third-party vision libraries. With a reliable feed, you can route it into a deep-learning inspection such as Rosepetal for AI-based defect detection.
Frequently asked questions
Yes. It uses a global shutter sensor, which exposes all pixels at the same instant. This captures moving objects without the skew or distortion typical of rolling shutters, making it well suited to inline inspection of parts in motion.
It connects over Camera Link and requires a compatible Camera Link frame grabber in the host. It supports Power over Camera Link (PoCL), so it can be powered through the interface where the grabber and cabling support it.
It is a monochrome camera. Without a colour filter array, every pixel contributes to luminance detail, which generally benefits resolution and light sensitivity for measurement, defect inspection and character reading where colour is not required.
The sensor is 25 MP with a 5120 px horizontal resolution, built on the Gpixel GMAX0505 with 2.5 um pixels on a 1.1" optical format. It runs at up to 30.7 fps.
It has a C-mount, so it accepts standard C-mount industrial lenses. Choose a lens that covers the 1.1" format and resolves the 2.5 um pixel pitch to make full use of the high-resolution sensor.
