The S9013 Fresnel Lens from SENBA is a precision-engineered optical component designed for passive infrared (PIR) motion detection systems requiring balanced range and wide-angle coverage. Manufactured from high-quality HDPE material, it delivers excellent infrared transmission efficiency, mechanical durability, and stable long-term performance for smart sensing applications.
This Fresnel lens is optimized to enhance PIR sensor accuracy by focusing infrared energy into well-defined detection zones, improving sensitivity and response reliability. It features a wide 120° detection angle with an effective sensing distance of up to 8 meters, making it suitable for mid-range motion detection applications in smart lighting, security, and automation systems. Its multi-zone optical structure helps reduce blind spots and ensures consistent detection performance.
With a compact 9mm design, the S9013 lens is easy to integrate into modern electronic devices and PIR sensor modules where both performance and space efficiency are required. The HDPE material ensures strong environmental resistance, stable optical behavior, and long service life.
Compared to standard Fresnel lenses, the S9013 provides improved detection range balance, enhanced infrared focusing capability, and reliable motion sensing performance for a wide range of applications.
