The KEYENCE LR-ZH490CB is a distance-based laser sensor from the LR-Z series designed for reliable object detection, presence/absence control, and position verification in industrial automation. By measuring distance instead of relying on color or contrast, it delivers stable performance on reflective machine parts, transparent packaging films, and dark components.

Built on the LR-Z platform with the U.C.D. function, the LR-ZH490CB maintains consistent switching even when target color, surface finish, or angle changes. Its laser spot enables precise alignment and background-independent detection up to 500 mm, supporting fast, repeatable sensing in assembly lines, packaging machinery, and intralogistics. Setup is straightforward with simple teach-in, reducing commissioning time and ensuring uniform results across devices.

Choose the LR-ZH490CB when you need compact, versatile photoelectric sensing that reduces false triggers, boosts throughput, and integrates seamlessly into existing controls; it is a dependable choice for OEMs and maintenance teams alike, and it comes backed by a 1-year warranty to safeguard your investment.
