Description

Pepperl Fuchs Retroreflective Sensor ML7-54-G/25/136/115b

Pepperl Fuchs Retroreflective Sensor

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.
