MD-L-Na Advanced Relay

The waterproof MD-L-Na Advanced Relay presence detector performs outstandingly in combination with Veko industrial lighting in narrow aisles with tall racks. Because of the detection angle and a combination of useful features, you can achieve maximum energy savings with this motion sensor. Not a single motion goes unnoticed by the extremely sensitive infrared (PIR) sensor of the MD-L-Na Advanced Relay, which registers and interprets changes in the thermal image extremely quickly.

The MD-L-Na Advanced Relay detector has various settings for detection sensitivity, turn-off delay and twilight sensor. A convenient remote control allows you to set the detector at the levels that suit you. Your lighting will not be on for example if there is enough daylight and will switch off, with a delay, when there is no more motion. You will always have the exact required amount of illumination everywhere.
