SICK CVS4-N122 2D Vision Sensor Unit

Module Feature

CVS4-N122 is an all-in-one compact 2D vision sensor from SICK CVS4 series.

It integrates image sensor, fixed-focus lens and internal illumination in a single housing. It supports barcode, QR code reading, OCV/OCR character verification and simple presence or dimension inspection. Compact IP67 design adapts to harsh workshop environments. Widely stocked as spare part for packaging, logistics and assembly automation stations.

Working principle

The built-in LED illuminates the target object, and the CMOS sensor captures the image.

The onboard processor runs pre-configured vision tools to decode codes, verify text or check feature existence. Inspection results and trigger signals are sent to PLC via digital I/O or Ethernet communication.

Onboard components

CMOS image sensor, fixed optical lens, integrated LED light source, image processing chip, I/O circuit, communication interface and sealed metal housing.

LED indicators

Front LEDs indicate power, trigger, pass and fail inspection status.

Hardware self‑diagnosis

Sensor monitors illumination brightness, image exposure and communication link health. Parameter setup and vision program editing are done on PC software.

Programming software

SICK CVS software, used for vision job configuration, tool setup, calibration and diagnostic log checking.
