Product Description

The SICK CS81-N1112 (1028228) is a premium high-performance color sensor designed for precise object detection and differentiation in demanding industrial environments. Utilizing a sophisticated RGB LED light source with wavelengths of 640 nm, 525 nm, and 470 nm, this sensor can identify and store a specific color with extreme resolution. It operates at an impressive adjustable switching frequency of up to 6 kHz, ensuring reliable performance in high-speed production lines.

The device features a user-friendly bar graph display that provides real-time feedback on color correspondence and detection reliability, simplifying the setup process via its static 1-point teach-in method. Its robust, rectangular zinc die-cast housing is IP67-rated, making it resistant to harsh conditions, dust, and water. With a compact 2 mm x 4 mm vertical light spot and a 12.5 mm sensing distance from the front edge of the lens, the CS81-N1112 excels at detecting small marks and subtle color differences that standard sensors might miss. This combination of speed, precision, and durability makes it a vital component for advanced automation and quality control systems.

Key Performance Features
