Basler racer 2 r2L4096-84g5m

r2L4096-84g5m

The Basler racer 2 r2L4096-84g5m is a compact 5GigE line scan camera built around the Gpixel GL3504 monochrome linear CMOS sensor with 4096 pixels and a 3.5 um x 3.5 um pixel size. It reaches a line rate of up to 84 kHz over a single 5GigE (RJ45) interface and supports 8, 10, and 12-bit output. The camera is compliant with GigE Vision 2.0 and GenICam, uses a C-mount, and is housed in a 55 x 29 x 29 mm body weighing 102 g. It is powered externally via the M8 6-pin I/O connector at 12-24 VDC, drawing roughly 5.8 W.

Technical overview

The Basler racer 2 r2L4096-84g5m is a true line scan camera, not an area camera, and that single fact shapes everything about how it is designed in. Instead of capturing a 2D frame, its Gpixel GL3504 monochrome linear CMOS sensor exposes a single row of 4096 pixels, each 3.5 um square, and the final image is built one line at a time as the part moves underneath. The full 4096-pixel width spans a 14.34 mm sensor format, so a continuous, seamless image of a moving web, sheet, or cylindrical surface is assembled from thousands of stacked lines. This is the right architecture when the object is continuous or rotating and an area camera would either miss the seams between frames or force you to stitch overlapping images. With a line rate of up to 84 kHz, the camera can keep pace with fast-moving material while preserving along-the-travel resolution, which is exactly what surface and defect inspection on web-fed lines demands.

The interface is a single 5GigE (RJ45) connection, which is the practical heart of this camera's value. 5GigE delivers roughly five times the bandwidth of standard GigE while keeping the same RJ45 cabling, standard Ethernet infrastructure, and cable lengths far longer than USB3 or the coax runs of CoaxPress, all over one inexpensive copper cable that also simplifies long-distance routing on a production line. That bandwidth is what lets a 4096-pixel mono sensor sustain 84 kHz without a frame grabber. The camera is compliant with GigE Vision 2.0 and GenICam, so it drops into any standard machine-vision software stack and is configured through familiar GenICam feature trees rather than a proprietary SDK. Output is selectable at 8, 10, or 12-bit, giving you 8-bit for fast throughput on high-contrast tasks and 10 or 12-bit when subtle grayscale gradations matter for finding low-contrast surface defects. The global shutter on the linear sensor ensures the whole line is exposed simultaneously, avoiding the smear a rolling readout would introduce on fast-moving product.

Mechanically and electrically the camera is built for compact, easy integration. It uses a C-mount, which keeps it compatible with the broad ecosystem of standard machine-vision lenses, though for a 14.34 mm line covered by a C-mount you should verify the lens delivers adequate image-circle coverage and resolving power across the full 4096 pixels. The body is just 55 x 29 x 29 mm and weighs 102 g, so it fits into tight gantries and traversing inspection heads. Power comes externally at 12-24 VDC (rated 10.8 to 30 VDC) through the M8 I/O connector, and consumption is a modest 5.8 W, which keeps heat low in enclosed housings. The M8 I/O connector also carries the I/O lines used to deliver an encoder or trigger signal, which on a line scan system is essential: line acquisition must be synchronized to web speed so the image is not stretched or compressed when the line slows or speeds up. Note the IP30 rating and the -10 to 50 degC operating range mean this is a controls-cabinet or enclosed-housing camera, not a washdown-rated unit, so dusty or wet environments will need a protective enclosure.

Best for

  • Continuous web surface inspection on printing, paper, film, and textile lines where a moving material must be imaged seamlessly at high speed
  • High-resolution defect detection on metal sheet, foil, and battery electrode surfaces, using 10 or 12-bit output to resolve low-contrast flaws
  • Inspection of rotating or cylindrical parts where line scan unwraps the full surface without frame stitching
  • Industrial OCR/OCV and code traceability reading on fast-moving packaging where 84 kHz keeps characters and codes sharp
  • Dimensional and edge measurement across wide product widths, leveraging the full 4096-pixel line for consistent cross-web accuracy

Selection notes

  • Line scan requires motion synchronization: plan for an encoder or external trigger wired through the M8 I/O connector so line acquisition tracks web speed and the image is not geometrically distorted
  • Lighting is critical and almost always bright, focused line lighting aligned precisely to the imaged line; because each exposure is extremely short at 84 kHz, budget for high-intensity illumination, typically strobed or continuous line lights
  • Confirm the C-mount lens fully covers the 14.34 mm sensor and resolves the 3.5 um pixels across all 4096 pixels, otherwise corner sharpness and effective resolution will suffer at the edges of the line
  • This is a monochrome camera; if your defect or print task depends on color discrimination, this model cannot provide it and you should plan for filtered or wavelength-specific lighting to maximize mono contrast instead
  • The IP30 rating and -10 to 50 degC range mean the camera needs a protective enclosure in dusty, humid, or washdown areas; verify external 12-24 VDC power and the roughly 5.8 W thermal load in your housing design
