ORNO OR-CR-219 DIN Rail Twilight Sensor with External Photocell, 230V AC, 10A, 2-100 Lux

The ORNO OR-CR-219 is a professional twilight sensor designed for DIN rail mounting (TH35). It automatically controls lighting based on ambient light levels, making it ideal for street lighting, garden illumination, and building facade lighting. The sensor features an external photocell with IP65 protection for outdoor use, while the DIN rail module is rated IP20 for indoor installation.

Advantages

Reliable automatic switching based on daylight intensity; adjustable light threshold from 2 to 100 lux; built-in time delay (approx. 1-2 minutes) prevents false triggering from transient light changes; easy installation on standard DIN rail; external photocell allows flexible placement for accurate light sensing.

Suitable for

• Automatic control of outdoor lighting (gardens, pathways, parking lots)
• Street lighting and public area illumination
• Building facade and sign lighting
• Energy-saving lighting automation in commercial and residential applications
