Omron / Sentech Sentech FS-B4KU7CLU-F

FS-B4KU7CLU-F

The FS-B4KU7CLU-F is a single-line monochrome line scan camera using an ams OSRAM DR-4K-7 CMOS global-shutter sensor with 4,096 horizontal pixels and a 7.0 µm pixel pitch. It outputs over a Camera Link Medium/Base interface (Camera Link 2.1, dual MDR connectors) at line rates up to 80 kHz, with selectable Mono8/Mono10/Mono12 pixel formats. The camera supports edge-preset, pulse-width and free-run trigger modes, flat field correction and field-update firmware, and is powered by +10.8 to +26.4 Vdc at 4.4 W or lower. It uses an F-mount and weighs approximately 250 g.

Technical overview

The Omron Sentech FS-B4KU7CLU-F is a single-line monochrome line scan camera built around the ams OSRAM DR-4K-7 CMOS sensor, which gives you 4,096 pixels across a single row at a 7.0 um pixel pitch. Unlike an area-scan camera that captures a 2D frame, this device images one line at a time and relies on relative motion between the part and the camera, building the full image line by line as product moves under the optics on a web, conveyor or rotating drum. That makes it a natural fit for continuous-process inspection where the material never stops: printed web, sheet metal, textile rolls and packaging film. The 80 kHz line rate is the headline number for the installer, because it directly couples to your maximum web speed and your achievable resolution along the travel direction. At 80,000 lines per second, the y-axis (motion-direction) sampling is set entirely by how fast the encoder ticks relative to that line rate, so a fast, well-coupled encoder is essential to keep pixels square and avoid stretching or compressing the image.

The sensor is described as a global-shutter CMOS device, which on a line-scan part means the whole line is exposed simultaneously rather than pixel-by-pixel, helping keep moving features crisp at high line rates. Output is over Camera Link in Medium/Base configuration (Camera Link 2.1, dual MDR connectors), and you can select Mono8, Mono10 or Mono12 pixel formats to trade bandwidth against tonal depth. Camera Link is a deterministic, low-latency wired interface, which is exactly why it remains common on demanding line-scan jobs, but it requires a matching Camera Link frame grabber in the PC and short, shielded MDR cabling rather than the plug-and-play simplicity of GigE or USB3. Plan for a grabber that supports Medium configuration if you intend to run the wider pixel formats at full rate. The camera also exposes edge-preset, pulse-width and free-run trigger modes, so you can drive line acquisition directly from an encoder edge (for constant spatial sampling regardless of speed variation), from a pulse width, or let it free-run for setup and stationary tests.

For an installer, the practical envelope is defined by the remaining specs. It carries an F-mount, which accepts the larger image circles needed to cover a 4,096 x 7.0 um line (roughly a 28.7 mm sensor width), so you must pair it with a line-scan-rated F-mount lens that resolves the 7 um pixel without falloff at the edges of the line. Built-in flat field correction lets you flatten illumination and lens shading non-uniformity across that wide line, which is critical because line-scan jobs live or die on even illumination. Power is a flexible +10.8 to +26.4 Vdc at 4.4 W or lower, so it runs comfortably from a 24 Vdc panel supply, and the compact 56 x 58 x 65 mm, 250 g body with a 0 to +40 deg C operating range suits in-line mounting near the process. Firmware is field-updatable, which matters for long-lived inspection lines that need feature or correction updates without hardware swaps.

Best for

  • Continuous surface and defect inspection of moving web material such as printed paper, film and foil, where the 80 kHz line rate keeps pace with fast line speeds
  • Wide-format sheet and roll inspection in metal, textile and packaging, using the 4,096 px line to cover a broad lane in a single pass
  • High-throughput print quality inspection and registration checking on rotary and web presses, driven by encoder-synchronized edge-preset triggering
  • Industrial OCR/OCV on continuously moving products where line-scan geometry avoids the seams and overlap of stitched area-scan images
  • Dimensional measurement along a moving edge or web, exploiting the consistent 7.0 um pixel pitch and global-shutter line exposure for stable geometry

Selection notes

  • Camera Link is not plug-and-play: you must budget for a matching frame grabber that supports Camera Link Medium/Base (2.1) and for short, shielded dual-MDR cabling, unlike a GigE or USB3 install
  • Y-axis resolution and image aspect are set by encoder coupling, not the camera alone; specify an encoder and trigger scheme (edge-preset for constant spatial sampling) so the 80 kHz line rate produces square pixels at your web speed
  • Choose a true line-scan F-mount lens that covers the full ~28.7 mm (4,096 x 7.0 um) line width and resolves 7 um pixels to the line edges; an area-scan lens will vignette or soften the ends of the line
  • Illumination uniformity is decisive for line scan: use the camera's built-in flat field correction together with a line light aligned to the imaged row, since uneven lighting across 4,096 px directly becomes defect noise
  • Confirm bandwidth headroom: Mono10/Mono12 increase per-line data versus Mono8, so verify the grabber and cabling sustain your chosen pixel format at 80 kHz before committing the line speed
