The 13120F-2 Fresnel Lens from SENBA is a compact and precision-engineered optical component designed for passive infrared (PIR) motion detection systems. Manufactured from high-quality HDPE material, it provides excellent infrared transmission efficiency, stable optical performance, and long-term durability for smart sensing applications.
This Fresnel lens is optimized to enhance PIR sensor sensitivity by focusing infrared radiation into multiple detection zones, ensuring accurate and responsive 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 lighting and electronic devices. The multi-zone optical structure helps reduce blind spots and improves overall detection stability and consistency.
With a compact 6mm design, the 13120F-2 lens is suitable for integration into space-constrained PIR modules and smart devices where both performance and size efficiency are critical. The HDPE construction ensures strong mechanical durability, environmental stability, and reliable infrared optical behavior over time.
Compared to standard PIR Fresnel lenses, the 13120F-2 offers improved compact integration, stable short-range detection performance, and enhanced infrared focusing capability for efficient motion sensing systems.
