German KOFRA sensors, KOFRA models, KOFRA prices

KOFRA 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 drive methods: one uses a permanent magnet for actuation, and the other uses an electromagnetic coil. The former is mostly used for detection; for example, if a moving part is made of a magnet, it will attract and trigger 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 close. Magnetic induction sensors are used to replace limit switches that rely on mechanical collision contact.
