PIR Motion Detector Lens | 22203

Directional Infrared Motion Sensor Lens with 20mm Focal Length for Wall-Mounted Infrared Sensing Applications

The 22203 PIR Fresnel Lens is a compact HDPE Fresnel optical component designed for wall-mounted infrared motion detection systems.
With a 20mm focal length, 45° directional sensing angle, and 15-meter detection distance, the lens provides focused infrared coverage for security sensors, automatic control devices and smart automation equipment.
Unlike wide-angle ceiling PIR lenses, the 22203 is optimized for directional detection scenarios where controlled sensing areas and reliable target recognition are required.
