Magnetic field sensors - Perfect integration even in harsh environments

Magnetic field sensors are frequently used in industry and building automation, especially where inductive sensors reach their limits. Despite their small design, the devices have a high switching distance and can therefore be perfectly integrated into all conceivable applications. Further advantages: The sensors operate contactless and are therefore completely wear-free.

There are many potential areas of application for magnetic field sensors: e.g. the inquiry of a rotation speed on conveyor belts or gear wheels, position checks of lifting devices, inclination angle inquiries or checking the alignment or position of a magnetic. ipf electronic has developed the MC080180 and MC080185 sensors specifically for this application, which can be used to differentiate between the north and south poles of magnets. This clear differentiation makes it possible to determine exactly whether a magnetic mounted on an object to be scanned is in the correct position and orientation. This means that two different positions on a linear axis, for example, can be clearly identified.

Faultless functioning is guaranteed even in the case of heavy soiling, but also if the magnetic object to be inquired is located behind a non-magnetizable material, e.g. non-ferrous metals, stainless steel, plastic, wood, etc. The switching distance depends on the strength of the magnetic field, which is determined by the material and the size of the magnet.

The slim and robust sensor housing in size M8 (length 59mm) contains the complete electronics. In addition to the housing, the sensor surface is also made of stainl. steel, which means that the IP67 protection class devices can withstand even oily and damp environmental conditions.

The solutions are suitable for operating temperatures from -25°C to +75°C. The connection is made via an industry-standard 3-pin M8 connection with integrated LED display. The switching frequency is 500Hz. The magnetic sensitivity of the devices is approx. 10mT.
