Product Overview
Leviton OSC20-MAW Ceiling-Mount Occupancy Sensor – Unused
You're looking at a Leviton OSC20-MAW ceiling-mounted occupancy sensor — a low-voltage, multi-technology control designed for commercial indoor lighting applications.
Built to observe a space without drawing attention to itself, this sensor combines complementary detection methods to maintain reliable presence sensing across real-world rooms where motion is not always obvious.
Product Condition
Unused, new old stock. The sensor has never been installed or placed into service. The manufacturer’s packaging shows wear from storage, but the unit itself is in clean, unused condition with no issues.
Product Overview
The Leviton OSC20-MAW is functionally equivalent to the OSC20-M0W: a 24 VDC, multi-technology (PIR and ultrasonic) ceiling-mount occupancy sensor rated for approximately 2,000 square feet with full 360-degree coverage in a white housing.
It is part of Leviton’s OSC20 series of low-voltage sensors and is intended to be used with a compatible external power pack or relay that performs the actual load switching. The sensor outputs a low-voltage control signal and does not switch line voltage directly.

Frequently Asked Questions
How does the OSC20-MAW compare to the OSC20-M0W?
The OSC20-MAW is equivalent in function to the OSC20-M0W: both are 24 VDC, multi-technology (PIR and ultrasonic), 360-degree ceiling-mount occupancy sensors rated for approximately 2,000 square feet. Final application details should always follow the datasheet for the exact catalog number used.
Does this sensor switch line voltage loads?
No. This is a low-voltage control device and must be used with a compatible power pack or relay to switch lighting loads.
What environments is this sensor designed for?
It is intended for indoor commercial spaces such as offices, classrooms, and similar areas within typical ceiling heights.
Has this unit been installed or used?
No. It is unused new old stock and was never installed.
Is code compliance guaranteed?
Code compliance depends on proper system design, installation, and compatible components. Buyers should consult current Leviton documentation for their specific application.
Designed to notice presence without making itself known, this sensor is ready to support a lighting system that responds only when the space truly needs it.
