The S9011 Fresnel Lens from SENBA is a high-performance optical component designed for advanced passive infrared (PIR) motion detection systems requiring extended range and wide-angle coverage. Manufactured from durable HDPE material, it ensures excellent infrared transmission efficiency, mechanical stability, and long-term reliability in both indoor and outdoor environments.
This Fresnel lens is optimized to enhance PIR sensor performance by focusing infrared radiation into precise detection zones, improving sensitivity and response accuracy. It provides a wide 120° detection angle with an extended sensing distance of up to 12 meters, making it ideal for long-range motion detection applications where broader coverage is required. The multi-zone optical design helps reduce blind spots and enhances overall detection stability.
With a compact 12mm structure, the S9011 lens is suitable for integration into modern motion sensor modules and smart devices that require high optical performance and efficient space utilization. The HDPE material ensures strong environmental resistance and consistent infrared optical behavior over time.
Compared to standard PIR lenses, the S9011 Fresnel lens delivers superior detection range, improved infrared focusing capability, and enhanced system reliability for professional motion sensing applications.
