Omron / Sentech STC-MBS70BU3V / STC-MCS70BU3V (7.1MP USB3 Vision)

STC-MBS70BU3V

The STC-MBS70BU3V (mono) and STC-MCS70BU3V (color) deliver 3216 x 2208 (7.1 MP) images at up to 51.2 fps over a USB 3.0 micro-B interface compliant with USB3 Vision 1.0.1. The camera uses Sony's 1.1" IMX428 global-shutter CMOS sensor with 4.5 µm square pixels, an exposure range of 1 µs to 16,777 s, analog gain of 0 to 19.2 dB and digital gain x1 to x2. It accepts USB bus power (+5 V) or external +8 to +24 Vdc with 5.9 W maximum consumption, and uses a C-mount in a 35 x 35 x 41.5 mm aluminium housing weighing about 78 g. Multiple trigger modes are supported (edge preset, pulse width, start/stop, free-run) over an operating range of 0 to +40 C.

Technical overview

At the core of the STC-MBS70BU3V (mono) and STC-MCS70BU3V (color) is Sony's 1.1-inch IMX428 Pregius global-shutter CMOS, delivering 3216 x 2208 px (7.1 MP) on 4.5 um square pixels. The global shutter is the defining trait for installers: every pixel is exposed simultaneously, so parts moving on a conveyor or rotating fixture are captured without the skew and smear that a rolling shutter introduces. That makes this camera a natural fit for any line where the target is in motion at trigger time, and it pairs cleanly with strobed lighting because the whole frame integrates light in one window. The large 1.1-inch optical format spreads those 7.1 megapixels across a generous active area, which keeps the pixels at a comfortable 4.5 um and supports good light gathering compared with cramming the same resolution onto a smaller sensor.

The camera reaches 51.2 fps at full resolution over a USB 3.0 micro-B interface compliant with USB3 Vision 1.0.1 and GenICam. USB3 Vision keeps cabling and host integration simple and low-cost over short runs and integrates with any GenICam-compliant software stack, but the trade-off versus GigE or CoaxPress is cable length: USB3 runs are short, so plan the camera-to-host distance carefully or budget for active/repeater cabling. The 7.1 MP resolution at 51.2 fps gives substantial throughput for high-resolution still inspection and moderate-speed in-motion capture. Exposure is controllable from 1 us to 16,777 s, so the same camera handles ultra-short strobe-frozen exposures and long integrations for dim scenes. Image quality is tuned with analog gain from 0 to 19.2 dB and digital gain x1 to x2, letting you lift signal in low light before resorting to digital scaling. Trigger flexibility is broad: edge preset, pulse width, start/stop, and free-run modes cover encoder-driven, PLC-gated, and continuous-acquisition workflows.

Mechanically and electrically the camera is built for straightforward design-in. It uses a standard C-mount, so the large pool of C-mount machine-vision lenses is available, though for a 1.1-inch sensor you must verify the lens image circle covers Type 1.1 to avoid vignetting at the corners. The aluminium housing is compact at 35 x 35 x 41.5 mm and light at about 78 g, which suits robot end-of-arm mounting and tight enclosures. Power can come from the USB bus (+5 V) or from external +8 to +24 Vdc, with a 5.9 W maximum draw, giving flexibility when the host port cannot supply enough current. The 0 to +40 C operating range is typical for controlled factory environments rather than hot or outdoor installations. The mono variant (STC-MBS70BU3V) maximizes sensitivity and per-pixel resolution for measurement, surface and OCR/OCV tasks, while the color variant (STC-MCS70BU3V) shares the same platform where color discrimination is required.

Best for

  • High-resolution defect and surface inspection of electronics, semiconductor and automotive parts where 7.1 MP detail and global-shutter accuracy matter
  • In-motion inspection on moving conveyors or rotating fixtures, capturing distortion-free images thanks to the IMX428 global shutter and short 1 us exposures
  • Dimensional measurement and metrology tasks that rely on the 4.5 um pixel pitch across a large 1.1-inch field for consistent, repeatable geometry
  • Industrial OCR/OCV reading of printed or marked codes and text, using the mono variant's full per-pixel resolution and high sensitivity
  • Robot-guidance vision where the compact 78 g aluminium body and C-mount fit end-of-arm or space-constrained mounting

Selection notes

  • Confirm the host setup supports a short USB 3.0 (micro-B) run; USB3 Vision is cost-effective but cable-length limited, so for longer distances plan active cabling or reconsider a GigE/CoaxPress interface
  • Choose a C-mount lens whose image circle covers the 1.1-inch (Type 1.1) sensor; many standard C-mount lenses are specified for smaller formats and will vignette on this sensor
  • Decide between the mono STC-MBS70BU3V and color STC-MCS70BU3V up front: mono gives maximum sensitivity and per-pixel resolution for measurement and OCR, color is only needed when hue discrimination is required
  • Verify host USB port power budget against the 5.9 W max draw, or wire the external +8 to +24 Vdc input when bus power (+5 V) is marginal
  • Pair the global shutter with strobed or pulse-triggered lighting and use the edge-preset or pulse-width trigger modes for in-motion capture; reserve free-run for continuous, static-scene acquisition
  • Keep the installation within the 0 to +40 C operating range; this camera targets controlled factory environments, not high-heat or outdoor mounting
