Senba S9001 Black Plastic Fresnel Lens for Smart Home System - 120° Viewing Angle
The Senba S9001 is a black plastic Fresnel lens designed for integration with Passive Infrared (PIR) sensors in smart home systems, security devices, and motion detectors. It provides precise optical focusing and wide-area detection coverage for enhanced sensor performance.
Features
- High-Density Polyethylene (HDPE) construction for durability and optical clarity.
- 120° wide viewing angle for expansive area coverage in rooms or outdoor spaces.
- 6mm focal length optimizes infrared signal focus onto PIR sensor elements.
- Snap-on design enables quick and tool-free installation on compatible sensor housings.
- Enhances detection reliability by segmenting the field into distinct thermal zones.

The Senba S9001 Fresnel Lens is a critical optical component engineered for passive infrared (PIR) motion detection systems. Its concentric groove pattern performs two primary functions: focusing ambient infrared radiation onto the pyroelectric sensor element and dividing the detection zone into alternating sensitive and blind sectors. This segmentation allows a moving heat source, like a human body, to create a fluctuating temperature signal on the PIR detector, triggering a reliable alert.
Constructed from black HDPE plastic, the lens is lightweight, impact-resistant, and maintains its optical properties across a wide temperature range typical for indoor and protected outdoor smart home applications. Its 120-degree viewing angle and 5-meter nominal detection distance make it suitable for covering entryways, hallways, and open-plan living areas when paired with a compatible PIR sensor module.
