LED Driver Sensor Switch SUNRICHER SR-8001A-DC 12–36V 8A — DC Motion/Light Control

The SUNRICHER SR-8001A-DC is a DC sensor switch for LED lighting systems, operating from 12–36V DC with a maximum output current of 8A. It integrates motion detection and ambient light sensing to control LED circuits automatically, enabling lights to turn on when movement is detected and remain off when ambient light is sufficient. The compact device is intended for installation in low-voltage LED applications such as corridors, stairways, cabinets and other small commercial or residential spaces where automated, energy-efficient lighting control is desired.

Advantages

The sensor combines motion detection and daylight sensing in a single unit, reducing the need for separate controls and simplifying wiring. Designed for DC LED loads, it supports a wide input range of 12–36V and a maximum continuous current of 8A, making it compatible with many low-voltage LED fixtures. Its automatic operation reduces energy use and extends LED lifespan by preventing unnecessary operation. The compact form factor allows for concealed mounting near fixtures or inside enclosures.

Suitable for

• Corridors and hallways in residential or small commercial buildings
• Stairwells and landings where automatic switching improves safety
• Cabinets, display cases and under-cabinet lighting
• Closets, storage rooms and utility spaces with intermittent use

Key specifications

• Supply voltage: 12–36V DC
• Maximum load current: 8A
• Functions: motion detection (PIR) and ambient light sensing
• Output type: DC switched output for LED loads
• Intended mounting: concealed or near-fixture installation

How to use

Install the sensor switch in accordance with local electrical regulations and ensure the supply voltage is within the 12–36V DC range. Connect the input power and LED load to the designated terminals, observing polarity and secure connections. Adjust or verify placement so the sensor has an unobstructed view of the monitored area for reliable motion detection. The unit will automatically switch the LED circuit on when movement is detected and keep it off when ambient light exceeds the sensor’s threshold.

Usage recommendations

For reliable operation, position the sensor to avoid direct exposure to strong light sources and heat-producing equipment. Use within the specified voltage and current limits and ensure proper heat dissipation for connected LED fixtures. Periodic visual inspection of connections and mounting is advised to maintain consistent performance.
