  • Innovative Bearing Technology: Non-Contact Magnetic Solutions
    The concept of non-contact bearings traces its roots back to the early 20th century when the theory of magnetic levitation and the utilization of magnetic fields to support loads gained prominence. However, it was not until the latter half of the century that significant advancements in magnetic
  • About Magnetic Sensors and Encoders
    Magnetic sensors indirectly measure properties such as direction, position, rotation, angle and current by detecting the magnetic field and its changes. Compared to other direct methods, such as optical or mechanical sensor, most magnetic sensors require some signal processing to get the property
  • Operating Principles for Magnetic Sensors
    Magnetic proximity sensors are actuated by the presence of a permanent magnet. Their operating principle is based on the use of reed con-tacts, whose thin plates are hermetically sealed in a glass bulb with inert gas. The presences of a magnetic field makes the thin plates flex and touch each other
  • Magnetic Field Sensors as Speed Monitors
    with integrated preloaded magnet, the contact-less potentiometer, which generates its signals with an external bar magnet and the incremental speed sensors respectively distance measuring sensors which material measure consists of a magnetic ring or magnetic tape. The resolution thereby ranges from almost
  • Magnetic Levitation for Precision Multi-Axis Positioning
    In this concept, magnetic levitation is used as multi-axis precision positioning concept based on non-contact propulsion and guiding principles. High performance motion control algorithms, low noise amplifiers and sub-nanometer resolution sensor technologies are used to achieve high precision
  • Non-Contact 3D Surface Metrology of Large Grain High Purity Niobium by SLCM and FESEM
    Abstract - Non-Contact 3D Surface Metrology of Large Grain High Purity Niobium by. SLCM and FESEM. Z.H. Sung, P.J. Lee and D.C, Larbalestier. Applied Superconductivity Center, National High Magnetic Field Laboratory,. Florida State University, FL, 32310.
  • Layout Considerations for Pulse Ethernet Magnetics and Ethernet Connector Modules
    or specific design guidelines, contact the supplier of the PHY you have chosen.
  • A Comparison of the Measured Magnetic Field Strength Using Ampere-Turns (AT) and milliTesla (mT) (.pdf)
    With the advent of the Reed Switch, developed by Bell Labs in the 1940s, it was convenient to measure its operate characteristics using the units of ampere turns. Since the Reed Switch is cylindrical it is easy to make the measurement of its closure, release and contact resistance using a coil
  • Coating Thickness Measurement: The Fundamentals
    . The magnetic induction method measures non-magnetic coatings over ferrous substrates and magnetic coatings over non-magnetic substrates. The process is direct, in that a probe is placed on the part to be measured. When the probe is positioned, the linear distance between the probe tip that contacts
