## Summary description

ORNO OR-CR-233 is a dusk sensor with an external light probe designed to switch lighting based on ambient illumination. Rated for up to 2300 W load, adjustable sensitivity from 2 to 100 lux, and dual ingress protection IP65 (probe) / IP20 (control unit). Intended for automated lighting control in residential and commercial indoor/outdoor installations where separate probe placement is required.

## Long description

ORNO OR-CR-233 is a dusk sensor with an external light probe designed to control lighting automatically according to ambient illumination. The device activates or deactivates connected lighting circuits when measured light falls below or rises above the set threshold. It supports loads up to 2300 W and features an adjustable sensitivity range from 2 to 100 lux. The external probe has IP65 protection for outdoor placement while the control unit is rated IP20 for indoor installation, allowing flexible placement of sensing element and electronics.
Advantages
The sensor provides precise dusk/dawn switching with a wide adjustable sensitivity range, enabling reliable operation in varied lighting environments. Separation of the external probe and control unit allows mounting the probe in optimal positions while keeping controls in sheltered locations. High load capacity makes it suitable for multiple lamps or higher-power circuits. Simple mechanical adjustment and clear functional behaviour reduce commissioning time and simplify daily operation.
Suitable for
Automatic switching of outdoor pathway, garden and facade lighting using an externally mounted probe
Indoor lighting control where the sensor electronics must be sheltered but the probe exposed to ambient light
Residential and small commercial installations requiring dusk/dawn control for energy saving and convenience
Control of multiple lamps or circuits within the sensor's rated load
Key specifications
Adjustable activation threshold: 2–100 lux
Maximum switching capacity: 2300 W (resistive loads)
External probe with IP65 protection for outdoor use
Control unit with IP20 protection for indoor mounting
White housing suitable for unobtrusive installation
How to use
Install the control unit indoors or in a protected enclosure and mount the external light probe in a location that represents the ambient illumination to be measured, avoiding direct artificial light sources. Connect the sensor in series with the lighting circuit according to local electrical regulations and ensure the load does not exceed the 2300 W rating. Adjust the sensitivity dial to the desired lux threshold between 2 and 100 lx so that lights switch on and off at the required ambient levels. Verify correct operation by observing switching behaviour at dusk and dawn or by simulating different light levels near the probe.
Usage recommendations
Place the external probe where it receives representative natural light and is protected from direct illumination by fixtures or reflective surfaces. Keep the control unit in a dry, ventilated indoor location. When controlling inductive or motor loads, check compatibility with the sensor switching type and derate the connected load if necessary. Regularly inspect the probe cable and connections for water ingress or mechanical damage.
