PIR Passive Infrared Sensor Module, 5–24VDC, 4A Output, Adjustable Delay

The C-SDC-IR-4A is a passive infrared (PIR) sensor module designed for automatic control of lighting, exhaust fans, and other electrical loads in corridors, bathrooms, basements, garages, warehouses, and similar applications. It operates on a wide-voltage DC input of 5–24V, making it compatible with a range of low-voltage control systems. The module features a 120-degree cone detection angle with a sensing range of 5–7 meters and supports continuous trigger mode. Output current is rated at 3A. Delay time is field-adjustable from 2 to 360 seconds via an onboard potentiometer. A temperature compensation circuit is included to minimize the effect of ambient temperature variation on sensing distance. Operating temperature range is -20°C to +50°C. Static current draw is less than 50µA. Unit dimensions are 50 × 40 × 22.5 mm (L × W × H). An optional photosensitive function can be configured to restrict operation to nighttime conditions only.
