Imperx T4840 Review: Specs & Applications
Updated: 7 days ago
Imperx T4840 is a 16 MP-class interline CCD camera using ON Semiconductor KAI-16070 interline CCD at 4864 × 3232 pixels. It uses Camera Link Medium with a documented rate of up to 7.6 fps. 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 T4840.
Quick Verdict
T4840 is a detailed-imaging CCD option for a Camera Link host system. The relevant purchasing case combines its KAI-16070 sensor with the intended optical field and a moderate full-frame rate. It is especially worth evaluating when a known CCD image pipeline or an existing acquisition architecture is part of the requirement. It should not be selected from the 16 MP label alone.

Design and Optical Requirements
The large-format KAI-16070 sensor requires an optical proposal appropriate to the image area. Lens coverage, focus and illumination should be tested across the required field. Preserve the position and mounting reference when comparing replacement cameras. A lens that worked with a smaller camera may not reveal the same feature at the outer image positions.
Acquisition Speed and Integration
The listed full-frame acquisition rate is up to 7.6 fps. That is a camera specification rather than guaranteed station throughput. Confirm Camera Link Medium support and the required pixel-stream interpretation on the selected frame grabber. Camera Link configurations should be compared explicitly rather than treated as a generic connector.
Programming and Image Processing
The documented capabilities include programmable image resolution, external triggering, strobe output, temperature monitoring, raw image access. Use those controls to establish a repeatable acquisition recipe for the station. Determine which adjustments are performed in the camera and which belong in the host software. Store the chosen settings with the inspection configuration so an operator or service technician can reproduce the image used during commissioning. A parameter change should be evaluated against both good and faulty samples before it becomes the production default.
Image Data and Host Capacity
As an engineering estimate, a 4864 × 3232 frame represented as one uncompressed 8-bit value per pixel contains about 15.72 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.
T4840 Applications and Use Cases
Imperx positions the Tiger family for machine vision and other imaging applications including aerial mapping and transportation. An industrial sample trial should demonstrate the relevant defects under production illumination. An imaging measurement should compare raw and corrected data deliberately, with recorded camera settings. Marketed applications do not establish certification or a measured accuracy for the final system.
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.
T4840 Price and Value
Price: Request a quote. Ask for the complete T4840 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
T4940 uses KAI-16050 at 4896 × 3264 and up to 8.8 fps, while T4840 uses KAI-16070 at 4864 × 3232 and up to 7.6 fps. The CXP sibling also changes the receiving architecture. Compare sensor geometry, optical coverage and host integration alongside nominal resolution.
Ordering, Environment and Lifecycle
Confirm the Camera Link ordering variant and the chosen Ruggedized or Industrial construction. Optional forced-air cooling changes the installation requirements. Request current supply, repair and driver guidance for the full ordering code, especially when maintaining a long-lived machine. Environmental claims should refer to the proposed assembly and its documentation.
Pros and Cons
Pros
Documented 16 MP-class interline CCD imaging.
Programmable acquisition and raw-data access.
Industrial and ruggedized configuration choices.
Cons
Moderate full-frame acquisition rate.
Camera Link Medium receiving hardware must match the configuration.
Optics, cooling and support scope require exact ordering details.
Who Should Buy T4840?
Shortlist T4840 when its documented sensor, interface and acquisition mode match the imaging task and the team can demonstrate the complete host pipeline. Use the sample trial to establish whether the relevant features remain distinguishable under the expected lighting, presentation and motion. Before purchase, settle the optical configuration, ordering variants and support requirements. The best choice is the configuration that satisfies the acceptance criteria with a maintainable system architecture.
T4840 FAQ
What is the native resolution of T4840?
4864 × 3232 pixels is the documented native image format. Evaluate the optics and required feature scale alongside that pixel count.
Which shutter architecture does it use?
The manufacturer describes an interline CCD camera with electronic exposure controls. Evaluate the specified exposure and trigger mode on the actual scene; this review does not transfer CMOS shutter specifications to the CCD camera.
What interface is required?
Camera Link Medium is the documented acquisition interface. Match the receiving hardware and software to the exact ordering configuration.
What is the maximum frame rate?
The documented rate is Up to 7.6 fps. Confirm the specified operating mode; maximum capture rate is not a guarantee of completed inspection throughput.
Which acquisition features are documented?
The product information includes programmable image resolution, external triggering, strobe output, temperature monitoring, raw image access. Configure the selected functions around the actual trigger and image-processing requirement.
What should be included in a system comparison?
T4940 uses KAI-16050 at 4896 × 3264 and up to 8.8 fps, while T4840 uses KAI-16070 at 4864 × 3232 and up to 7.6 fps. The CXP sibling also changes the receiving architecture. Compare sensor geometry, optical coverage and host integration alongside nominal resolution.
How much does the camera cost?
Price: Request a quote. Include the exact camera variant, optics, receiving hardware, power, cables and commissioning.
What should be tested before ordering?
Test representative good and faulty samples, the intended optical geometry, image timing, capture diagnostics and the complete result association with each inspected part.
Price: Request a quote. Final configuration, pricing, availability and support terms depend on the supplier's current quotation.
