5A Recessed Ceiling Microwave Sensing For Automatic Lighting
The RZ048-5A is a recessed ceiling-mounted microwave motion sensor switch for indoor automatic lighting control where a low-profile ceiling form 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.
功能、优点和规格
The RZ048-5A combines 5A AC lighting control, recessed mounting, and 5.8 GHz microwave detection so installers can verify load fit, placement, and setup before ordering.
功能与优点
- 5A line-voltage control: Supports 100-265 VAC lighting circuits with the source-backed RZ048-5A load ratings shown in the specifications.
- 5.8 GHz microwave sensing: High-frequency Doppler detection actively senses movement for ceiling-mounted automatic lighting control.
- Recessed ceiling form: Screw mount or spring clip mounting supports a low-profile ceiling installation with the documented 82-90 mm cutout.
- 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.

常见问题
How is the RZ048-5A different from a PIR ceiling sensor?
RZ048 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 RZ048-5A 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.
What ceiling opening does the spring clip mount need?
The manual lists an 82-90 mm circular ceiling hole for spring clip mounting.
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.
Where should the RZ048 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.
