M7LL ‐ / M70LL Laser sensors are maintenance free. Because these are optical measurement unit, the optical system has toe be kept
free from dirt and dust. This means: the optical system needs to be cleaned from time to time.

Tipp: cleaning should be done with a soft towel.
You could use alcohol and / or bezine.
Avoid finger prints and grease; remove these quickly after mounting!

please note: oily finger prints cause severe measurement errors. The same applies to water drops or other liquids.

During the installation of sensors take care that no sunlight could radiate ‐ directly or reflected on a surface ‐ into the sensors
receiving optics. This could cancel the function of the sensor.

Water drops on the optic system or on the front make severe distortion on the measurement. Water drops work like a lens. They
may cause sensors to fail permanently.

Standard sensors were delivered with laser wavelength of 650 ... 670 nm. For special purpose and on request MEL will deliver other
laser wavelength. The technical data for those sensors are basically the same as for 650 nm sensors. Sensors using different
wavelength would not interfere into each other optical system. This allows to use two laser sensors having a laser spot near to the
other sensor without interference problems. Sensors with different laser wavelength may hav different laser safety class or different
technical data.
