"Telemecanique Inductive Proximity Sensors OsiSense XS series (extended sensing range) allow you to detect all types of objects in all applications providing high detection performance for metal objects. This inductive sensor range with industry recognised high performing technology provide non-contact detection of material up to 20 mm. Inductive proximity sensors are available in flush and non-flush models (shielded and non-shielded). OsiSense inductive proximity sensors are purely for detecting any metal objects up to 60 mm and include an oscillator with windings (an alternating magnetic field is generated in front) making up the sensing phase."
