Merrytek MSA070 IR PIR Motion Sensor DALI-2 35mm + Daylight
The modern DALI-2 PIR motion sensor from Merrytek is an advanced solution for intelligent lighting control in DALI systems. The device combines motion detection with a light intensity (lux) sensor, allowing it to automatically turn on, off, and dim lighting based on user presence and lighting conditions.
Thanks to its compact design and flush-mounted design (Ø35 mm hole), the sensor is ideal for modern installations – it remains virtually invisible when mounted in the ceiling.
Key Features:
PIR (infrared) motion sensor
DALI-2 protocol support (IEC 62386)
Built-in daylight sensor 0–1200 lux
Automatic lighting control (ON/OFF / dimming)
Parameter adjustment via remote control or DALI system
Settings: - Detection sensitivity (25% / 50% / 75% / 100%) - Backup time (2 s – 30 min)
Very low power consumption
Technical Specifications:
Power supply: DALI bus (9.5–22.5V DC)
Current consumption: max. 7 mA
Output signal: DALI-2
Detection range: up to 8–10 m
Detection radius: approx. 4–5 m (at 3 m height)
Mounting height: 2.5–4 m
Mounting: flush-mounted (Ø35 mm hole)
Operating temperature: -25°C to +50°C
Ingress protection: IP20
Certifications: CE, RoHS
Applications:
Corridors and passageways
Offices and commercial spaces
Hotels and public buildings
Toilets and technical rooms
DALI-2 intelligent lighting systems
Functionality:
The sensor detects motion using PIR technology and automatically controls lighting via the DALI system. It also analyzes daylight levels and can prevent lighting from turning on when it's not needed.
Configurability allows you to tailor the sensor's operation to the specific conditions and needs of the installation.
Advantages:
Automation and energy savings
Compact Ø35 mm installation
Integration with the DALI-2 system
Precise and stable detection
Ideal for professional applications
