SICK KTX-WB9214125AZZZZ Industrial Photoelectric Sensor

The SICK KTX-WB9214125AZZZZ is a compact contrast sensor from the KTX Prime family that uses RGB LED illumination and IO-Link for precise color/contrast detection within a 13 mm sensing range. It features a 3.8 mm × 0.9 mm light spot, a 5‑pin M12 connection, and a Push‑Pull output that can be wired as NPN or PNP, with IO-Link support for straightforward controller integration. Power is supplied from 10.8 to 28.8 V DC (nominally 12 V or 24 V) and the device draws up to 100 mA; it offers multiple teach modes (two‑point teaching, dynamic teaching, and automatic/auto modes) and RGB LED indicators for status. The RGB light source covers wavelengths 470 nm, 525 nm, and 625 nm, and the housing dimensions are about 30 mm (G) × 53 mm (H) × 78.5 mm (D), built for standard industrial environments. Typical applications include color/contrast verification such as label or mark detection, color‑based sorting, and quality‑control checks on production lines.
