The Imaging Source DFK 23GP031 Review: Specs & Lifecycle
Updated: 7 days ago
DFK 23GP031 is a legacy color camera from The Imaging Source, listed by Rochester Imaging Technology in the supplied catalog. Its documented image is 2592 × 1944 through GigE with model-specific PoE arrangement. Current manufacturer lifecycle information identifies discontinuation. Price: Request a quote.
The camera should be selected as part of an imaging system rather than evaluated from one headline specification. The useful result is an image that reveals the required feature at the right time, followed by a reliable inspection or measurement decision. This review considers the documented acquisition package, optical implications and practical purchasing scope for DFK 23GP031.
Quick Verdict
DFK 23GP031 is most relevant when documenting or maintaining an existing acquisition system and planning a validated replacement. Its five-megapixel rolling-shutter image can support a controlled scene, but the required motion and result timing must be tested. For a new machine, compare a current supported alternative before choosing legacy stock.

Design and Optical Requirements
Select optics for the 1/2.5-inch sensor and intended object field. Verify the C/CS adapter and final working distance before reusing an existing lens. The denser image can support finer sampling, but lens contrast and field focus still determine useful detail. Include normal target height and placement variation in the optical trial.
Acquisition Speed and Integration
The legacy sheet lists up to 15 fps through GigE with model-specific PoE arrangement. Rolling-shutter acquisition requires attention to row timing when the target or camera moves. A trigger input does not turn the sensor into a global-shutter model. Validate the actual receiving hardware, supported output and full acquisition-to-decision timing.
Programming and Image Processing
The legacy supplier material identifies acquisition software and integration support for its original platforms. Verify which current driver and application environment can operate the installed camera. Preserve the exact exposure, output, trigger and inspection settings with the machine. When migrating, validate command behavior, pixel interpretation and error handling rather than assuming that a previous software recipe transfers unchanged.
Image Data and Host Capacity
As an engineering estimate, a 2592 × 1944 frame represented as one uncompressed 8-bit value per pixel contains about 5.04 MB of pixel data, using decimal megabytes. This excludes transport overhead and metadata. It is a sizing example, not a measured camera transfer rate; other output representations change the data volume. Multiply the selected frame size by the planned acquisition rate when budgeting host memory, processing and storage, then validate the complete pipeline under realistic load.
DFK 23GP031 Applications and Use Cases
Existing color inspection or instrument imaging can merit a documented maintenance and migration trial. Use the original normal, faulty and borderline samples where available. Confirm that exposure, field and software interpretation reproduce the required decision. A replacement image that looks similar to an operator can still change the inspection threshold or timing.
Building a Useful Acceptance Trial
Prepare representative parts or scenes that include the smallest required feature, normal production variation and realistic faults. Confirm the field of view and exposure before tuning the inspection. Record wrong accepts, wrong rejects, missing frames and the complete trigger-to-decision timing. A trial should also show what happens when the expected image is absent or unusable. This connects camera selection to the station's actual acceptance requirement rather than relying on a sharp reference picture.
DFK 23GP031 Price and Value
Price: Request a quote. Ask for the complete DFK 23GP031 ordering code and an itemized scope covering the camera, suitable optics, receiving hardware, cables, power and commissioning. Compare quotations for the same image format, acquisition mode and integration scope. The cost of a camera component is different from the cost of a working inspection station. Evaluate any financial return with the plant's actual labor, defect, rework and maintenance data; no universal payback period follows from these specifications.
Comparison and Selection
Compare DFK 23GP031 with DMK 23GP031 on whether the decision needs color information rather than a monochrome stream. The listed successor DFK 33GR0521 should also be evaluated for new or migrated designs. Match field, shutter, trigger and software behavior rather than replacing on megapixel count alone.
Ordering, Environment and Lifecycle
The April 22, 2024 manufacturer notice lists a last-time-buy date of May 17, 2024. The supplier recommends DFK 33GR0521 as a replacement in the applicable lifecycle information. Confirm the current successor, stock, repair terms and supported software directly before purchase. A downloadable legacy factsheet is not evidence that the old model remains in production.
Pros and Cons
Pros
A documented legacy image format supports existing-system analysis.
Manufacturer lifecycle information identifies a replacement path.
A controlled migration trial can preserve the required inspection behavior.
Cons
The model is discontinued.
Replacement optics, timing and software require validation.
The old acquisition arrangement should not be assumed compatible with a current camera.
Who Should Buy DFK 23GP031?
Evaluate DFK 23GP031 when maintaining a legacy installation and a documented supply and support arrangement meets the requirement. For a new system or planned migration, compare the current recommended successor and other supported options using the actual acceptance samples.
