Basler boost boA1936-400cm

boA1936-400cm

The Basler boost boA1936-400cm is a high-speed industrial area scan camera built on the 2/3" Sony IMX421 mono CMOS global-shutter sensor with 1936 x 1472 px (2.8 MP) resolution and 4.5 µm pixels. It connects via a single CoaXPress 2.0 (CXP-12) channel through one Micro-BNC connector at up to 12.5 Gbps, reaching roughly 364 fps at full resolution and up to ~401 fps in 8-bit mode. The camera offers a universal lens front available in C-mount, F-mount, and M42 variants, and can be powered via Power over CoaXPress (PoCXP) or an external 24 VDC supply through the I/O connector. It conforms to GenICam and CoaXPress 2.0 standards, typically consuming about 7.9 W at 24 VDC.

Technical overview

The Basler boost boA1936-400cm is a high-speed area scan camera built around the 2/3" Sony Pregius IMX421 mono CMOS sensor, a 2.8 MP global-shutter device (1936 x 1472 px) with 4.5 µm pixels on an 8.7 x 6.5 mm imaging area. The global shutter is the defining trait here: every pixel is exposed simultaneously, so fast-moving objects on a conveyor or a rotating part image without the skew and smear a rolling shutter would introduce. That makes this camera suited to inline tasks where parts do not stop, and the monochrome sensor maximizes light sensitivity and per-pixel detail, which is exactly what surface-defect and edge-based dimensional work want. At 2.8 MP the resolution is modest by today's standards, so this is a speed-first sensor rather than a fine-detail one; the trade is throughput, not pixel count.

Speed is the reason this model exists. It connects over a single CoaXPress 2.0 (CXP-12) channel through one Micro-BNC connector at up to 12.5 Gbps, and that bandwidth lets the sensor run at roughly 364 fps at full resolution and up to about 401 fps in 8-bit mode. CoaXPress carries data, trigger, control, and power over one coax cable, so cabling stays simple even though the data rate is high. You will need a matching CXP-12 frame grabber in the host PC, which is the architectural commitment that separates this from plug-and-play GigE or USB3 cameras: the grabber handles the timing and offloads the link, but it is a fixed part of the bill of materials. Power can come over the cable via PoCXP or from an external 24 VDC supply through the I/O connector (rated 18.6-26 VDC), with typical consumption around 7.9 W.

On the optics and integration side, the camera offers a universal lens front available in C-mount, F-mount, or M42 variants, giving flexibility to match the 11.0 mm sensor diagonal to the right lens image circle. C-mount covers most short-to-medium focal lengths, while F-mount and M42 are there for larger-format or longer-reach optics. The box-style housing measures 45 x 80 x 80 mm and weighs 436 g, operates from 0-50 °C, and conforms to GenICam and CoaXPress 2.0 so it drops into standard machine-vision toolchains. Because the sensor runs so fast, exposure times are short, which means lighting becomes the limiting factor: pairing the camera with strong, well-controlled illumination and using the CoaXPress trigger to strobe lighting in sync with each frame is essential to getting clean, consistent images at hundreds of frames per second.

Best for

  • High-speed inline surface inspection where parts move continuously and global-shutter capture is needed to avoid motion smear
  • Defect and surface-quality detection on fast conveyors in electronics, automotive, and semiconductor production
  • Dimensional and edge-based measurement of moving parts where crisp, distortion-free frames matter
  • High-throughput packaging inspection where hundreds of frames per second keep pace with line speed
  • Applications already committed to a CoaXPress frame-grabber architecture that need a single-cable, long-reach link

Selection notes

  • Requires a CoaXPress 2.0 (CXP-12) frame grabber in the host PC; budget for it and the slot space, since the camera cannot run on a standard NIC or USB port
  • The ~364 fps full-resolution rate climbs toward ~401 fps only in 8-bit mode, so confirm your inspection tolerates 8-bit depth if you need the top frame rate
  • At 2.8 MP this is a speed-oriented sensor, not a high-detail one; if fine feature resolution drives the application, a higher-megapixel model may fit better
  • Short exposures at high frame rates demand bright, well-synchronized lighting; plan to drive strobed illumination from the CoaXPress trigger
  • Match the lens front (C-mount, F-mount, or M42) and image circle to the 2/3" / 11.0 mm diagonal sensor, and decide early between PoCXP and external 24 VDC powering for your wiring layout
