The Leviton OSC20-M0W occupancy sensor is a ceiling-mounted, low-voltage multi-technology sensor designed to automatically control lighting based on room occupancy. It combines PIR and ultrasonic sensing to deliver reliable detection across large indoor spaces up to 2,000 sq. ft.
- Leviton® OSC20-M0W Low Voltage Occupancy Sensor, 24 VDC, PIR/Ultrasonic Sensor, 2000 sq-ft Coverage, 360 deg Viewing, Ceiling Mount
PIR + Ultrasonic Multi-Technology Detection → Combines precise motion detection with high sensitivity for minor movement, improving reliability in real-world conditions
Self-Adjusting Operation → Internal microprocessor continuously optimizes sensitivity and time delay, reducing manual calibration and user complaints
2000 sq. ft. Coverage with 360° Viewing → Provides wide-area monitoring for open spaces, minimizing the number of sensors required
Automatic ON / Automatic OFF Control → Ensures lights operate only when needed, supporting energy efficiency
Adjustable Time Delay (30 sec – 30 min) → Allows customization based on occupancy patterns for better control of lighting runtime
Ambient Light Sensing (20–3000 Lux) → Prevents lights from turning on when sufficient natural light is available
Walk-Through Mode → Automatically shortens delay time when occupancy is brief, increasing energy savings
Non-Volatile Memory → Retains learned settings during power interruptions, ensuring consistent performance
Simple Low-Voltage Installation → Three-wire connection with twist-lock mounting for fast ceiling installation
LED Activity Indicators → Visual feedback for PIR and ultrasonic detection simplifies setup and diagnostics

What makes the Leviton OSC20-M0W occupancy sensor reliable for large spaces?
It uses both PIR and ultrasonic technologies. PIR detects initial motion accurately, while ultrasonic sensing detects smaller movements, ensuring lights remain on while the space is occupied.
Can the sensor adjust automatically after installation?
Yes. A built-in microprocessor continuously analyzes usage patterns and automatically adjusts sensitivity and time delay for optimal performance.
Does the sensor prevent lights from turning on during daylight?
Yes. It includes an ambient light sensor (20–3000 lux) that blocks activation when enough natural light is present.
What type of installation does this sensor require?
It is a ceiling-mounted, low-voltage device using a three-wire connection and twist-lock attachment for easy installation.
Is the Leviton OSC20-M0W occupancy sensor suitable for energy code compliance?
Yes. It can be used to meet IECC, ASHRAE 90.1, and Title 24 occupancy sensing requirements.
