The N0803-32 Fresnel Lens from SENBA is a compact, high-precision optical component designed for passive infrared (PIR) motion detection systems. Manufactured from durable HDPE material, it provides excellent infrared transmission efficiency, stable optical performance, and long-term reliability for smart sensing and automation applications.
This Fresnel lens is engineered to improve PIR sensor sensitivity by focusing infrared radiation into multiple detection zones, enabling accurate and stable motion detection. It features a wide 120° detection angle with an effective sensing distance of up to 5 meters, making it ideal for short-range motion sensing applications in compact smart devices and lighting systems. Its multi-zone optical structure enhances signal concentration, reduces blind spots, and improves overall detection consistency.
With a compact 6mm design, the N0803-32 lens is well-suited for integration into space-limited electronic products and PIR sensor modules where both performance and size efficiency are critical. The HDPE material ensures strong mechanical durability, environmental stability, and consistent infrared optical behavior over time.
Compared to standard PIR Fresnel lenses, the N0803-32 offers improved compactness, reliable short-range detection performance, and enhanced infrared focusing capability for efficient motion sensing systems.
