This HDPE Fresnel lens is an optical component specifically engineered for Passive Infrared (PIR) sensor modules. One side features a smooth surface while the opposite side incorporates concentric ring patterns that focus infrared radiation onto the PIR sensor element.

The lens operates by concentrating infrared energy from moving objects within the detection range onto the PIR sensor, which converts the optical signal into an electrical signal to activate connected systems.

• Simple installation process
• Consistent quality and reliability
• Competitive factory-direct pricing

• Specifically designed for Passive Infrared sensor applications
• Ideal for compact, low-profile sensor designs
• Suitable for security systems, lighting controls, and environmental monitoring
• Optimized for dual-element pyroelectric devices
• White light immunity minimizes false triggers
• UV resistant for outdoor applications
• Uniform sensitivity design reduces electronic gain requirements
