Contrast Sensors

KT6W-N5116 is a high-performance contrast sensor from SICK, designed for reliable detection of colour marks and contrasts on packaging and labels in industrial automation. It features a robust metal housing (30.4 x 53 x 80 mm), a sensing distance of 10 mm (±2 mm tolerance), and uses RGB LED technology (wavelengths: 640 nm, 525 nm, 470 nm) for precise detection. 

The sensor provides an NPN switching output, a fast switching frequency of 5 kHz, and easy setup using a 2-point teach-in function. It operates on 10–30 V DC, connects via a 4-pin M12 connector, and is rated IP67 for dust and water protection, ensuring durability in demanding environments
