Steinel WLS 1-LA Wall Switch Occupancy Sensor

Steinel IR WLS 1-LA is a line-voltage, single-relay Passive Infrared wall switch occupancy sensor designed to automatically control lighting in commercial spaces. The 66110 designation identifies the Light Almond (LA) color variant, aligning with Steinel’s WLS 1-LA line. This wall-switch sensor uses PIR detection to sense occupancy and switch the connected lighting load on when movement is detected and off when the space becomes vacant, functioning in Automatic ON mode. As part of Steinel’s WLS 1 family, it is intended for indoor wall-mount installations and provides a dedicated relay output for a single lighting circuit. The IR WLS 1-LA supports straightforward retrofit and new-construction applications where energy savings and hands-free lighting control are desired, delivering reliable presence-based control in spaces such as offices and other commercial environments while matching standard electrical installations.
