As a professional manufacturer in occupancy sensors for sustainable building control solutions, we strive to develop innovative products that not only allow you to provide occupancy sensing based building control, but also offer versatile selections for OEM lighting fixture integration. We strive to deliver maximum energy savings through simple and effective sensor controls.
The best controls are the ones you don't even realize are there at all.
LOS‑505SF LOS-505SW
Occupancy Sensor

The LOS‑505SF (fixture integration) and LOS-505SW (IP-66 fixture integration) are line voltage occupancy sensors with control logic in reverse of typical occupancy sensing control. A pair of voltage free, normally closed (NC) dry contact outputs will be open for a period of programmable delay times when the sensor detects occupancy.
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.
