SICK D 7808 NT8-02 Photoelectric Sensor

The SICK D 7808 NT8-02 Photoelectric Sensor is part of SICK’s NT8 contrast-scanner family, a non-contact optical sensor designed to detect contrast marks on moving materials. The NT8-02 variant is a specific model within the NT8 line used for registration and contrast sensing on label, film, or printed-media lines. Listings from surplus vendors describe the unit as new surplus or opened factory packaging, and a commonly cited weight is about 1.15 pounds; several sources also indicate the NT8-02 is discontinued by the manufacturer. The NT8 family is described as a contrast sensor that detects differences in light reflection to identify marks or edges, enabling reliable registration tasks in manufacturing settings for process control and quality assurance.
