Omron / Sentech Sentech STC-SPB891PCL / STC-SPC891PCL (8.9MP Camera Link)

STC-SPB891PCL

The STC-SPB891PCL (monochrome) and STC-SPC891PCL (color) are industrial area scan cameras using the 1-inch Sony IMX255 global-shutter CMOS sensor at 4096 x 2160 (8.9 MP) with 3.45 um square pixels. They output over Camera Link (80-bit / Full / Medium / Base, Camera Link 2.1) at up to about 91.5 fps via dual SDR connectors, with a C-mount lens interface. Power is supplied via PoCL or external +12 VDC through an HR10A-7R-6PB connector, consuming 3.5 W or less. The compact 35 x 35 x 40.7 mm body weighs approximately 71 g and operates from 0 to +45 degC.

Technical overview

The STC-SPB891PCL (monochrome) and STC-SPC891PCL (color) are area scan cameras built on the 1-inch Sony Pregius IMX255 global-shutter CMOS sensor, delivering 8.9 MP at 4096 x 2160 px on 3.45 um square pixels. The combination of a global shutter and a true 1-inch optical format is the defining characteristic here: the global shutter freezes the entire frame in a single exposure, so parts moving on a conveyor, indexing stage, or rotating fixture are captured without the skew or smear that a rolling shutter introduces. With 3.45 um pixels across a 1-inch active area, the sensor balances spatial resolution against well capacity, which makes it a practical workhorse for inspection where you need both fine detail and clean motion capture rather than maximizing one at the expense of the other.

The interface is Camera Link, supporting 80-bit / Full / Medium / Base configurations under Camera Link 2.1, and the camera runs at up to roughly 91.5 fps through dual SDR connectors. Camera Link is a deterministic, low-latency wired interface, so it is well suited to high-speed inspection lines where frame timing must be tightly coupled to triggers and where you want the full 8.9 MP at high frame rate without the bandwidth ceilings of consumer interfaces. Reaching the top frame rate requires the wider Full / 80-bit modes; narrower Medium or Base configurations trade some throughput for simpler cabling and frame grabber requirements, so the running mode should be matched to the frame grabber and the actual line speed you need to sustain. The camera exposes GenICam-compatible control, which keeps integration consistent with standard machine-vision software stacks and frame grabbers.

Optically the camera uses a C-mount, so it pairs with the broad ecosystem of C-mount lenses, but the 1-inch sensor format means you must select lenses rated to cover a 1-inch image circle to avoid vignetting and corner softness at the array edges. Power comes either over the cable via PoCL or from an external +12 VDC supply through the HR10A-7R-6PB connector, with consumption rated at 3.5 W or less, which simplifies cabling on PoCL-capable frame grabbers. The body is compact and light at 35 x 35 x 40.7 mm and roughly 71 g, easing mounting on gantries, robot arms, or tight multi-camera fixtures, and it is specified for 0 to +45 degC ambient operation. Because the sensor is fast and high resolution, exposures are short, so the camera should be designed in alongside adequately bright, well-controlled lighting and external triggering to fully exploit the global shutter at speed.

Best for

  • High-speed surface and defect inspection on moving lines, where the global shutter freezes motion at up to ~91.5 fps without distortion
  • Dimensional and metrology measurement that needs the 8.9 MP (4096 x 2160) field, taking advantage of the deterministic Camera Link timing for precise, repeatable captures
  • Electronics and semiconductor inspection where the 3.45 um pixels resolve fine features and the 1-inch sensor maintains image quality across the frame
  • Industrial OCR/OCV on print, marking, and labels, using the monochrome SPB variant for maximum contrast or the color SPC variant where color is part of the read
  • Packaging and printing inspection on fast indexing stations where high frame rate and low-latency triggering keep pace with the line

Selection notes

  • This is a Camera Link camera, so it requires a compatible frame grabber and Camera Link cabling; budget for the grabber and confirm it supports the configuration (80-bit / Full / Medium / Base) you intend to run, since the full ~91.5 fps depends on the wider modes
  • The 1-inch optical format demands lenses that cover a 1-inch image circle; a smaller-format lens will vignette, so verify lens image-circle rating along with the C-mount thread
  • Choose the variant deliberately: SPB (monochrome) gives the best sensitivity and contrast for inspection, measurement, and OCV, while SPC (color) is for tasks where color information is required
  • Plan power and cabling around PoCL (power over the Camera Link cable) or an external +12 VDC supply via the HR10A-7R-6PB connector; PoCL reduces cable count but requires a PoCL-capable grabber, and the camera draws 3.5 W or less
  • Short exposures at high frame rate need bright, controlled illumination and external trigger/strobe pairing to realize the global shutter's motion-freezing benefit; design lighting in from the start, and respect the 0 to +45 degC operating range for thermal placement
