The unique and extremely popular design of the MLV41 series enables it be mounted correctly in confined areas and offers all the functions that are normally only found on larger phototelectric sensors.The MLV41 series comes with a range of functions grouped together under the VISO+ quality symbol.For example,highly visible status LEDs on the front and back,resistance to ambient light,crosstalk protection and universally applicable output stages that permit every possible switching logic and polarity to be realized.The enhanced resistance to ambient light ensures reliable operation even where modern energy‑saving lamps with electronic ballasts are in use.The same applies where multiple devices are present,i.e. the use of a number of sensors in the same vicinity causes no problems.
