Best Trading Partner PIR Motion Detector Fresnel Lens | Ø23.4mm | Focal 10.5mm | 120° Wide Angle for Smart Home Systems


Trusted by global brands, Yuying Optical delivers precision infrared and PIR Fresnel lenses with full customization, fast delivery, and consistent quality for smart sensors, lighting, and industrial systems.


How PIR Motion Detector Fresnel Lenses Work
The 023100 lens focuses infrared radiation from human bodies onto a pyroelectric sensor, dividing the detection area into multiple zones. When movement occurs within the 120° detection range, the sensor triggers the motion detector switch. The HDPE lens ensures stable IR transmission and consistent performance for smart home automation.

Customized Services

Yuying offers customized Fresnel lenses based on customer requirements, including different sensing angles, detection distances, sizes, and test ratios. All of our products are made using original molds, preserving the accuracy of the original design and reducing the precision loss and time delays caused by secondary mold changes. New products are typically available for sample delivery within 30 days.





Advantages




  1. Durable HDPE Material – High infrared transmittance and long service life.
  2. Wide Detection Angle – 120° sensing area reduces blind spots.
  3. Long Sensing Distance – Detects movement up to 10 meters accurately.
  4. Compact Design – Perfect for wall-mounted or miniaturized smart switches.
