HS Code pour capteurs de position linéaires sans contact

HTS Code :

The items concerned are referred to as Temposonics® “R-Series” non-contact linear position sensors. The two models subject to this instant ruling are the RP profile-style and the RH rod-style. Both sensors are used for continuous operation in industrial applications such as fluid cylinders, and function by utilizing the “magnetostrictive” position sensing principle, whereby a sonic strain pulse (electrical signal) is produced by the momentary interaction of two magnetic fields. One field comes from a moveable permanent magnet that passes along the outside of the sensor while the other field comes from an interrogation current pulse applied along the waveguide. This electrical signal travels at sonic speed along the waveguide, and is detected at the head of the sensing element which acts as a “slave” device that transmits its position and status data to a “master” device, such as a programmable logic controller (PLC). Each position sensor is a common type of electromagnetic transducer that is used to convert the rectilinear motion of an object into a corresponding electrical signal.^[1]
