STC-MBS322CXP6

The STC-MBS322CXP6 (monochrome) and STC-MCS322CXP6 (color) are 3.2MP area-scan cameras built on a 1/1.8" Sony IMX252 global-shutter CMOS sensor with 2,048 x 1,536 effective pixels and a 3.45 µm pixel pitch. They use a single-lane CoaXPress CXP-6 interface over a 75-ohm BNC connector compliant with CoaXPress Standard v1.1.1, delivering up to 152.0 fps and powered via PoCXP (Power over CoaXPress) at 3.5 W or less. The 28 x 28 x 40 mm C-mount body weighs about 52 g and supports trigger modes (edge preset, pulse-width, CXP trigger packet, free-run), ROI, binning, decimation, and an exposure range of 1 µs to 16.777 s with 0 to 42 dB analog gain. Pixel formats are Mono8/10/12 on the monochrome model and BayerRG8/10/12 on the color model.

Technical overview

The STC-MBS322CXP6 (monochrome) and its MCS322CXP6 color twin pack a 3.2 MP, 1/1.8" Sony IMX252 Pregius global-shutter CMOS sensor into a 28 x 28 x 40 mm C-mount body that weighs just 52 g. The 2,048 x 1,536 array on a 3.45 µm pixel pitch is the well-established IMX252 building block, and the global shutter is the defining trait here: every pixel is exposed simultaneously, so fast-moving parts on a conveyor, indexing turntable, or robot-mounted gripper are frozen without the skew or smear a rolling shutter would introduce. With an exposure window from 1 µs to 16.777 s and 0 to 42 dB of analog gain, the same camera covers bright strobe-frozen high-speed capture at the short end and long integrations for dim scenes at the long end. That flexibility, plus the small footprint, makes this a natural fit for tight machine enclosures and moving axes where larger camera bodies will not go.

Where this model separates itself from GigE or USB3 alternatives is the interface: a single-lane CoaXPress CXP-6 link over a 75-ohm BNC connector, compliant with CoaXPress Standard v1.1.1. CXP-6 carries the full 3.2 MP frames at up to 152 fps over a single coax cable that can run far longer than USB3 and still hold deterministic, low-latency timing. Power arrives over that same coax via PoCXP (Power over CoaXPress) at 3.5 W or less, so a single cable handles data, power, and trigger back-channel, cutting harness count on the machine. The trade-off versus GigE/USB3 is that CXP requires a frame grabber in the host PC rather than a standard network or USB port, so this camera is aimed at PC-based vision stations built around a CoaXPress acquisition card, not at plug-and-play setups.

On the imaging side, the monochrome MBS variant outputs Mono8/10/12 and the color MCS variant outputs BayerRG8/10/12, letting you trade bit depth against bandwidth and choosing mono for maximum sensitivity and contrast or color where part discrimination depends on hue. Built-in ROI, binning, and decimation let you push frame rate well past the full-frame figure by reading out only the region or resolution you need, which matters when a measurement only occupies part of the field. Trigger support spans edge preset, pulse-width, the CXP trigger packet delivered over the coax uplink, and free-run, so the camera can be hard-synchronized to an encoder, PLC, or strobe controller. Because the lens is a separate C-mount component, pair it with a C-mount optic whose image circle covers the 1/1.8" format and whose resolving power matches the 3.45 µm pixels, and add controlled lighting (often strobed and synced to the trigger) to make the short exposures and 152 fps usable in practice.

Best for

  • High-speed inline inspection on fast conveyors or indexing lines where the global shutter freezes motion at up to 152 fps without skew
  • Defect and surface inspection of electronics, semiconductor, and battery parts where the 3.2 MP resolution and mono sensitivity reveal fine flaws
  • Dimensional measurement tasks where global-shutter geometry and a stable 3.45 µm pixel pitch support repeatable gauging
  • Robot-guidance and pick stations on moving arms where the 28 x 28 mm, 52 g body fits tight end-of-arm and in-machine spaces
  • Multi-camera CoaXPress vision cells that need long, single-cable runs with deterministic timing and PoCXP-powered cabling

Selection notes

  • This is a CoaXPress CXP-6 camera over a 75-ohm BNC: it requires a matching single-lane CoaXPress frame grabber in the host PC, so budget for a grabber rather than a standard NIC or USB port
  • Confirm your acquisition card supplies PoCXP, since the camera is powered over the same coax at 3.5 W or less and has no separate power input shown in the specs
  • Choose between the MBS (Mono8/10/12) and MCS (BayerRG8/10/12) variants up front: mono maximizes sensitivity and contrast for measurement and surface defects, color is for hue-based discrimination
  • Spec a C-mount lens that covers the 1/1.8" optical format and resolves the 3.45 µm pixel pitch; the lens is not included and will dominate achievable image quality
  • To reach 152 fps with usable exposure, plan controlled, often strobed lighting synced through the camera's edge, pulse-width, or CXP trigger packet modes, and use ROI/binning/decimation to lift frame rate beyond full-frame where the task allows
