## Summary description

The F&F AZH-S-24V is a twilight switch designed for automatic lighting control based on ambient light intensity. Featuring an external hermetic probe, it operates within a 2-1000lx range and requires a 24V power supply. This device is ideal for outdoor lighting systems, ensuring energy efficiency by activating lights only when natural light levels drop below the set threshold.

## Long description

The F&F AZH-S-24V is a professional twilight switch engineered for the automated management of lighting systems based on real-time ambient light intensity. By utilizing an external hermetic probe, the device accurately monitors light levels and triggers connected circuits when natural illumination falls below a user-defined threshold. This solution is designed to enhance energy efficiency by ensuring that outdoor or indoor lighting remains active only during periods of insufficient daylight.
Advantages
The primary benefit of this twilight switch is its ability to provide reliable, hands-free lighting control, which significantly reduces energy consumption and operational costs. The inclusion of a hermetic external probe ensures that the light-sensing component is protected against harsh environmental conditions, such as rain, dust, and humidity, allowing for flexible installation in various outdoor locations. With a wide sensitivity adjustment range, users can precisely calibrate the device to meet specific site requirements, ensuring optimal performance in diverse lighting environments.
Suitable for
Automatic control of street and garden lighting
Illumination of building facades and architectural elements
Lighting management for parking lots and driveways
Energy-efficient operation of billboard and signage illumination
When it may not be suitable
This device is not intended for use in systems requiring high-voltage mains power, as it is strictly designed for 24V DC/AC circuits. It may also be unsuitable for environments where light sources are positioned in a way that causes the sensor to trigger a continuous cycle of switching on and off due to direct light exposure.
Key specifications
Supply voltage: 24V AC/DC
Light intensity adjustment range: 2-1000lx
Probe type: External hermetic sensor
Operating temperature range: -25°C to +50°C
Mounting: DIN rail or surface mount depending on configuration
How to use
Installation should be performed by a qualified professional in accordance with local electrical regulations. The control unit is typically mounted within an electrical cabinet, while the hermetic probe is installed in a location exposed to natural daylight but shielded from direct artificial light sources. Once installed, the sensitivity threshold can be adjusted using the integrated dial to match the desired activation level. The device will then automatically monitor ambient light and switch the connected load accordingly.
What to consider before purchase
Ensure your power supply system is compatible with 24V requirements
Verify that the cable length between the probe and the control unit is sufficient for your installation site
Confirm that the intended load does not exceed the maximum switching capacity of the relay
Usage recommendations
For optimal performance, position the external probe away from direct artificial light sources such as street lamps or security lights, as these can interfere with the sensor's ability to detect natural twilight. Regularly inspect the probe for debris or obstructions to maintain accurate light sensing.
