LOS‑502SF LOS-502SW
Occupancy Sensor

The LOS‑502SF (fixture integration) and LOS-502SW (IP-66 fixture integration) are line voltage occupancy sensors for traditional on/off switching control. The sensor comes with ambient light sensor (ALS) to inhibit the lighting if ambient light levels are higher than required.
The sensor can be mounted on the ceiling, or integrated with a lighting fixture in various formats via specific mounting brackets available.
Different lenses can be applied to provide specific coverage at different mounting heights.
