The SB-F-02 Fresnel Lens from SENBA is a high-performance optical component designed for passive infrared (PIR) motion detection systems requiring long-range and wide-angle sensing capability. Manufactured from durable HDPE material, it ensures excellent infrared transmission efficiency, mechanical strength, and stable long-term optical performance in smart sensing applications.
This Fresnel lens is engineered to enhance PIR sensor accuracy by concentrating infrared energy into precise multi-zone detection patterns. It provides a wide 120° detection angle with an extended sensing distance of up to 10 meters, making it ideal for long-range motion detection in both indoor and outdoor environments. The multi-zone optical structure improves signal focusing, reduces blind spots, and ensures stable and reliable motion detection.
With an 11.5mm compact form factor, the SB-F-02 lens is suitable for integration into modern PIR modules and smart devices where both high performance and space efficiency are required. The HDPE construction offers strong environmental resistance, stable optical behavior, and long service life under varying conditions.
Compared to standard Fresnel lenses, the SB-F-02 delivers improved detection range, enhanced infrared focusing efficiency, and more consistent motion sensing performance for advanced applications.
