Product information
Small, robust, effective, and reliable - these
are the properties of the ML7 sensor series.
Due to their small size, number of versions,
and two different lens positions, they are par-
ticularly suited for installation in tight spaces.
The robust design and high quality of Pep-
perl+Fuchs mean they can also be used
under harsh environmental conditions. The
efficient technology, switching frequencies up
to 1000 Hz, high resistance to ambient light,
and 4-in-1 output make the series suitable for
non-contact object detection.
