The LILLIPUT® is an electronic device able to receive the emission of infrared beams emanating from a body at a distance until 6m. The presence of a warm body moving in the area controlled by the sensor take the power stage of the device, switching the load. A dusk sensor can inhibit the power of the device if the area light level is above the threshold for lux set. Until the body heat stays is moving, through the beams of sensitivity, the adjustable timer from 4 sec to 10 minutes continues to reset keeping the load. The settings of lux threshold of operation and time are accessible on the front of the device, making easier the calibration even after installation. The intersection of zones of sensitivity to multiple sensors, including different versions, does not cause interference, so is possible to use multiple elements in the same area. Static version TE36 .. with two wires connection can be inserted in place of a switch to control resistive loads only. TE37 ..R version relay with three-wire connection has a relay output with 1 contact C-NA 5A cosφ=1 bound to the supply voltage for the activation of resistive or inductive loads.
