KTX-WS91141242ZZZZ Contrast Sensor 13mm PNP/NPN | SICK

The Original New SICK KTX-WS91141242ZZZZ (Part No. 1078167) is a high-precision contrast sensor from the KTX Prime series, engineered for reliable detection of contrast marks in high-speed printing, packaging, and converting applications. Featuring an RGB LED light source with TwinEye technology, it delivers stable, colour-independent detection of even low-contrast marks. The vertical light spot (0.9 mm × 3.8 mm) and 13 mm sensing distance enable precise targeting of narrow register marks. With a 50 kHz switching frequency and 10 µs response time, this sensor is built for demanding high-throughput production lines.
