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 particularly suited for installation in tight spaces.
The robust design and high quality of Pepperl+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.
