Senba S9004 HDPE Optical Fresnel Lens for PIR Sensors - 8m Detection, 100° Viewing Angle
The Senba S9004 is a high-density polyethylene (HDPE) Fresnel lens designed to focus infrared radiation onto Passive Infrared (PIR) sensor elements, enhancing detection range and sensitivity for security and automation systems. It features a 10.5mm focal length, an 8-meter detection distance, and a 100° viewing angle for broad coverage.
Features
- HDPE (High-Density Polyethylene) construction for durability and optical clarity.
- Optimized for PIR sensors with a 10.5mm focal length and 100° wide viewing angle.
- Enhances sensor detection range up to 8 meters for improved system coverage.
- Standard 22.5mm diameter and 3-pin footprint for easy integration into existing sensor housings.
- Concentric groove design efficiently focuses IR radiation onto the sensor element.

The Senba S9004 Fresnel lens is a critical optical component for Passive Infrared (PIR) motion detection systems. Its concentric groove pattern on one side focuses ambient infrared radiation from a wide 100° field of view onto the pyroelectric sensor element, significantly increasing its sensitivity and effective detection range to 8 meters. The smooth opposite side protects the optical surface.
Manufactured from transparent HDPE, this lens offers a high-value balance of optical performance, environmental resistance, and mechanical durability. It is a direct-fit component designed for integration into standard PIR sensor modules, alarm systems, and human presence detection switches, forming the essential optical interface between the environment and the sensing electronics.
