The S9012 Fresnel Lens from SENBA is a compact, high-precision optical component designed for passive infrared (PIR) motion detection systems requiring short-range and wide-angle sensing performance. Manufactured from durable HDPE material, it provides excellent infrared transmission, stable optical characteristics, and reliable long-term operation in smart sensing applications.
This Fresnel lens is optimized to improve PIR sensor accuracy by concentrating infrared radiation into defined detection zones, enabling stable and responsive motion detection. It features a wide 120° detection angle with an effective sensing distance of up to 3 meters, making it ideal for close-range applications where precise and fast detection is required. The multi-zone optical structure enhances infrared focusing, reduces blind spots, and improves overall detection consistency.
With an ultra-compact 5mm form factor, the S9012 lens is well-suited for integration into small electronic devices and space-constrained motion sensor modules. The HDPE material ensures strong mechanical durability, environmental stability, and consistent optical performance over time.
Compared to standard PIR lenses, the S9012 Fresnel lens delivers improved compactness, faster short-range detection response, and enhanced infrared focusing efficiency for precision motion sensing applications.
