Infrared PIR Motion Sensor Automatic Light Switch » ENG Stores A PIR (Passive Infrared) motion sensor light switch automatically turns on a light when it detects motion from a heat-emitting source, like a person or animal.
Specifications
PIR motion sensor light switch specifications vary, but common features include a detection angle (e.g., 120° or 180°), detection range (e.g., 3-8 meters), load capacity (e.g., 6A or 1200W, with some requiring derating for fluorescent lights), delay time (e.g., adjustable from 1-10 minutes or fixed), and voltage (e.g., 120V AC or 12-24V DC). Many models have adjustable settings for sensitivity and duration, and some require a neutral wire for installation.
Common specifications
Sensor Coverage:
Detection Angle: Varies from 120° to 180° or even 360° for ceiling-mounted versions.
Detection Range: Typically between 3 and 8 meters (approx. 10 to 26 feet).
Load Capacity:
Maximum Load: Can be specified in watts or amps.
AC models: May handle 600W for incandescent/halogen or 1/6 HP for motors at 120V.
DC models: Often have a max current of 6A or 8A.
Load Type: Some switches have specific limits for different load types, such as fluorescent lights, which may require the load to be derated.
