SICK KTS-WS91141142ZZZZ Contrast Sensor
Product Overview
The SICK KTS-WS91141142ZZZZ is a high-speed contrast sensor designed to detect printed marks and differences in contrast between a mark and its background. It uses RGB LED technology to identify contrast variations reliably, even when materials or printing colours are similar. With a sensing distance of up to 13 mm and a response time of just 10 µs, it is suitable for fast-moving production processes. This sensor is ideal for packaging, printing, labelling and automated manufacturing systems where accurate mark detection is essential.
