LDT‑7xx Series

Line Voltage Dual‑Tech Wall Switch Sensor

The LDT type of the WALLSENZR family are dual technology line voltage wall switch sensors for direct load switching of general lighting control. This wall switch combines digital Passive Infrared (PIR) and High Frequency Doppler (HFD) sensing technologies into an aesthetically pleasing housing to provide second-to-none occupancy/vacancy sensing based lighting control for all applications. The LDT type provide 2 poles of hybrid switching control for all types of lighting.

Occupancy‑Vacancy sensor changeable control
Dual‑tech or single HFD sensing mode switchable
Front accessible sensor operation configurations
No grid opening - aesthetics pleasing sensor front
4 levels of HFD sensitivity setting programmable
180° field of view with coverage exceeds 100 sq. m.
Specialized lens provides vandalism protection
Accu‑Set digital potentiometer sensor settings
Dual Hybrid‑Switching technology for HIC load control
Screwless wall plate offers high end appearance
Low cut back cover provides more wiring space
