5A Ceiling Microwave Sensing For Automatic Lighting
The RZ047-5A is a ceiling-mounted microwave motion sensor switch for indoor automatic lighting control where overhead sensing is preferred over a wall switch.
It uses 100-265 VAC live, neutral, and load wiring, with push-button adjustment for time delay, Lux threshold, and high/low sensitivity after installation.

360-Degree Microwave Coverage For Everyday Rooms
Microwave Doppler sensing can detect movement through many non-metal materials such as glass, plastic, and thin partitions, which helps ceiling placement cover practical indoor room layouts.
Because that same sensitivity can also detect movement outside the intended area, installers should reduce sensitivity or relocate the sensor when doors, windows, partitions, metal surfaces, or moving fixtures cause nuisance triggering.
Features, Benefits, Specs
The RZ047-5A combines 5A AC lighting control, 5.8 GHz microwave detection, and adjustable ceiling-sensor settings so installers can verify load fit, placement, and setup before ordering.

Features & Benefits
- 5A line-voltage control: Supports 100-265 VAC lighting circuits with the source-backed RZ047-5A load ratings shown in the specifications.
- 5.8 GHz microwave sensing: High-frequency Doppler detection actively senses movement for ceiling-mounted automatic lighting control.
- 360-degree ceiling coverage: Ceiling placement gives broad room coverage with an 8-12 m detection diameter under manual conditions.
- Non-metal material penetration: Microwave detection can pass through many plastics, glass, and thin partitions, while metal blocks detection.
- Adjustable time delay: Choose 15 s, 30 s, 1 min, 3 min, 5 min, 10 min, or 30 min to match room traffic patterns.
- Selectable Lux threshold: Set Off, 15 Lux, 25 Lux, or 35 Lux so the load responds to motion only when the ambient-light condition fits the installation.
- High/low sensitivity: The SENS button helps reduce nuisance detection through doors, glass, partitions, or adjacent spaces.

FAQ
How is the RZ047-5A different from a PIR ceiling sensor?
RZ047 uses high-frequency microwave Doppler sensing. It can detect through many non-metal materials such as glass, plastic, and thin partitions, while metal blocks detection.
Does the RZ047-5A need a neutral wire?
Yes. The AC wiring diagram requires White to Neutral, Red to Load, and Black to Live.
What loads can the 5A model control?
The manual lists 500 W / 110 VAC and 1100 W / 220 VAC for incandescent or halogen loads, and 250 W / 110 VAC and 500 W / 220 VAC for fluorescent, ballast, or LED loads.
Can microwave sensing trigger from outside the room?
Yes. The manual warns that microwave sensing can detect through glass, doors, or partitions, so sensitivity should be reduced or the sensor relocated if nuisance detection occurs.
What settings can installers adjust?
Installers can adjust time delay, Lux threshold, and high/low sensitivity using the buttons under the top cover.
Where should the RZ047 be installed?
The manual lists a 2.5-5 m installation height and recommends avoiding windows, doors, automatic doors, rotating equipment, HVAC airflow, fans, moving machinery, vibrating fixtures, and large metal surfaces.
