Dusk Sensor FF AZH 10A 230V 2–1000 lx IP65 — ambient light switch for lighting control

Dusk Sensor FF AZH is an ambient light switch designed for automatic lighting control. The device measures surrounding illuminance and closes or opens the output circuit when set thresholds are reached. Rated for 10 A at 230 V and with an adjustable sensitivity range from 2 to 1000 lx, this sensor supports precise control of exterior and interior lighting. Its IP65 enclosure provides protection against dust and low-pressure water jets, making it suitable for exposed mounting points where reliable operation and weather resistance are required.

Advantages

The FF AZH offers a broad sensitivity range to accommodate low-level twilight detection as well as brighter conditions, reducing manual intervention. Its 10 A switching capacity covers most lighting loads such as LED fixtures, halogens and compact fluorescents when used within their electrical specifications. IP65-rated housing ensures durability in outdoor environments while the straightforward control principle simplifies installation and integration into existing lighting circuits.

Suitable for

• Exterior building and façade lighting
• Security and flood lights
• Street lamps and pathway illumination
• Signage and advertising illumination
• Energy-saving automation for indoor lighting where ambient control is needed

Key specifications

• Operating voltage: 230 V AC
• Switching capacity: 10 A
• Adjustable sensitivity: 2–1000 lux
• Protection rating: IP65 (dust-tight and protected against water jets)
• Operating principle: ambient light level controlled switching

How to use

Install the sensor at a location that represents the typical ambient light conditions for the controlled lighting. Mount the unit following local electrical regulations and ensure correct mains isolation before wiring. Adjust the sensitivity dial or control to the desired lux threshold so the connected lighting switches on or off at the required ambient level. After wiring and adjustment, test operation at different light levels to confirm correct switching behaviour.

Usage recommendations

Place the sensor away from direct artificial light sources such as the controlled lamps or nearby streetlights to avoid false triggering. For reliable outdoor performance, mount the device with the sensor element oriented towards the open sky and avoid obstructions. When controlling LED or electronic ballast loads, verify that inrush currents and driver compatibility fall within the sensor’s switching capacity.
