Basler racer 2 S r2L4096-42g5c

r2L4096-42g5c

The r2L4096-42g5c is a member of the Basler racer 2 S line scan family, equipped with a Gpixel GL3504 color linear CMOS sensor (4096 pixels, 3.5 µm pitch, 14.34 mm sensor format, 12-bit) operating in global-shutter mode at a maximum line rate of 42.6 kHz. Its 5GigE interface (also supporting Fast/1GigE/2.5GigE) enables higher line rates than 1GigE while running standard GigE Vision and GenICam protocols. The compact 62.2 x 29 x 29 mm C-mount housing weighs under 105 g, is powered by 12-24 VDC over the M8 6-pin I/O connector (~6.5 W typical), and carries an IP30 rating. The camera targets factory automation and inspection applications such as surface and web inspection.

Technical overview

The Basler racer 2 S r2L4096-42g5c is a color line scan camera built on the Gpixel GL3504 linear CMOS sensor, a single row of 4096 pixels at a 3.5 µm pitch across a 14.34 mm sensor format. As a line scan device it captures one line at a time and relies on relative motion between the camera and the part, typically a moving web, conveyor, or rotating drum, to build a seamless two-dimensional image free of the stitching seams an area-scan array would leave. The 4k width gives generous across-web resolution: spread across a wide field of view it holds fine detail, and used over a narrow strip it delivers very high spatial sampling for small-defect detection. Color capture means it discriminates by hue as well as contrast, which matters for print registration, label verification, and material grading where a defect is defined by color rather than geometry alone.

Line rate is the throughput-defining number on any line scan camera, and this model runs up to 42.6 kHz, meaning it can expose and read out 42,600 lines per second. That headroom sets the maximum belt or web speed for a given encoder resolution: the faster the line rate, the finer the down-web pixel spacing you can hold at a given travel speed, or the faster you can run the line at a fixed resolution. The sensor operates in global-shutter mode, so every pixel in the line integrates over the same window, avoiding the per-pixel timing skew of rolling readout, important when imaging fast-moving product. At 12-bit depth the camera resolves subtle tonal gradations useful for low-contrast surface flaws. Encoder-synchronized line triggering is essential to keep the aspect ratio constant when line speed varies; pair the camera with a quadrature encoder feeding its trigger input so each captured line corresponds to a fixed increment of travel.

Connectivity is over 5GigE, which lifts the available bandwidth well beyond a 1GigE link and is what makes the full 42.6 kHz line rate practical over a standard Ethernet cable run; the interface is backward compatible down to Fast, 1GigE, and 2.5GigE, so it can drop into existing lower-speed network infrastructure at reduced throughput. It speaks GigE Vision and GenICam, so it integrates with standard machine-vision software stacks without proprietary drivers. The housing is a compact C-mount body of 62.2 x 29 x 29 mm weighing about 105 g, powered at 12-24 VDC through an M8 6-pin I/O connector at roughly 6.5 W typical, and rated IP30 for clean indoor enclosures. The C-mount lens interface and 14.34 mm sensor format dictate lens selection, you need a line scan capable lens with an image circle that covers 14.34 mm and the resolving power to match the 3.5 µm pixels. Because line scan exposures are brief, bright, stable line illumination aligned to the scan line is effectively mandatory; a high-output line light running in continuous or strobed mode under controller management is the natural lighting partner.

Best for

  • Continuous web and surface inspection of printed media, film, paper, and foil where a seamless image of a moving substrate is required
  • Wide-format or fine-pitch surface defect detection on conveyor-fed product, using the 4096-pixel width either across a broad field or as a high-resolution narrow strip
  • Color-dependent print and label inspection, verifying registration, ink coverage, and hue consistency in printing and packaging lines
  • High-speed roll-to-roll textile and material grading where line speed is matched to the 42.6 kHz line rate via encoder triggering
  • Electronics and packaging surface inspection feeding AI-based defect detection, where uniform global-shutter color lines improve downstream classification

Selection notes

  • Specify an encoder-synchronized line trigger into the M8 6-pin I/O so down-web resolution stays constant as line speed varies; without it the image stretches or compresses with belt speed changes
  • Size the optics for the 14.34 mm sensor format and C-mount thread: the lens image circle must cover 14.34 mm and resolve the 3.5 µm pixel pitch, otherwise across-web sharpness limits effective resolution
  • Confirm your network path supports 5GigE end to end (NIC, cabling, switch) to realize the full 42.6 kHz line rate; on 2.5GigE/1GigE/Fast links the camera still runs but at reduced throughput
  • Budget bright, line-aligned illumination; line scan exposure windows are short, so a high-intensity line light, run continuous or strobed through a controller, is needed to fill the 12-bit dynamic range at full speed
  • Plan the install for IP30 and a -10 to 50 °C operating range, meaning a clean indoor enclosure; provide stable 12-24 VDC power for the ~6.5 W typical draw
