Product Description:

The VSS122R21.M51P-000 is a compact vision device in B&R Automation's VS Smart Sensors series for integrated machine-vision tasks on automated production lines. It combines optics, illumination, and onboard computing in one enclosure, allowing direct inspection or guidance without an external PC. The unit supports one active vision function, such as code reading or presence checking, for quality control and robot positioning. This integrated design reduces separate hardware at the point of use and keeps image evaluation close to the machine process. Because image capture and evaluation occur inside the device, response times stay short and integration remains straightforward in compact cells.

Its embedded Cortex A9 i.MX6 quad-core processor runs at 800 MHz, and 4 cores share 1 MB of L2 cache for image preprocessing. Coupled with 2 GB of RAM, the unit can buffer image frames when line speed changes. The imaging pipeline operates at 90 fps, which supports fast indexing applications and short inspection windows. Optical input passes through an F4, 1/1.8-inch macro lens secured to an S-mount, while LED lens type 2 helps distribute light evenly. The front window uses anti-reflective glass to reduce flare from surrounding machine lighting, and the standard preprocessing setup is intended for area-scan operation rather than line-sensor use. That arrangement supports repeatable inspection results when parts move quickly through the viewing area.

The device offers a 37° field of view and a resolution of 1.3 MP, providing fine image detail at common working distances. Close-range focus is supported by the 12 mm macro optics, and the integrated lighting ring contains 16 LEDs arranged in four multicolored segments that can emit red, blue, infrared, or white light. This combination helps the sensor adapt to different surface finishes, contrast conditions, and marking types without requiring separate external illumination. Segmented color control can also improve contrast on mixed materials and reflective labels. The built-in lighting reduces the need for separate illumination hardware where space around the inspection point is limited.
