German PHI DESIGN sensor PHI DESIGN model PHI DESIGN price

PHI DESIGN sensors are devices that convert magnetic signals into electrical signals. By leveraging the transformation relationship between magnetic quantities and other physical quantities, using a magnetic field as the medium, they can also convert signals of other non-electrical physical quantities into electrical signals. There are two driving methods: one uses permanent magnets, and the other uses electromagnetic coils. The former is mostly used for detection; for example, if a moving part is made of a magnet, it will attract and emit a signal once it approaches the magnetic induction sensor. The latter is mostly used for control; if the electromagnetic coil is energized, the contacts will attract. Magnetic induction sensors are used to replace collision-based contact
