    Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size and are the second-strongest type of permanent magnet made. Their max energy product is at least three times that of alnico 8 and at least five times that of ferrite. SmCo has higher temperature ratings and higher coercivity than neodymium. They are also highly corrosion resistant and do not require a coating. disc sensor smco magnet

    Attributes of Samarium-Cobalt Magnets
    Often referred to in the industry as SmCo Magnets.
    More expensive than other materials
    High Hc and Hci
    High Bhmax
    Can withstand high operating temperatures, up to 350°C.
    Powerful for size
    Corrosion resistant and do not require a coating
    Samarium-Cobalt magnets are brittle, and prone to cracking and chipping. Allowing magnets to snap together will cause the magnets to shatter.
    Samarium-Cobalt Price Sensitivity
    Due to the Cobalt content used to manufacture these magnets, Samarium-Cobalt Magnets fluctuate in price more than other materials.

    Angle Position On-Axis
    The magnetic rotary position sensor product family detects the absolute angular orientation of an on-axis two-pole magnet rotating over the center of the IC. The absolute angular position can be provided in various formats, including PWM, ABI and UVW, or directly read through the host interface. According to the application’s requirements, resolutions from 8-bit up to 14-bit are available. This technology can be employed in high-accuracy angle position detection, high-speed rotation systems and brushless DC motor control. Any rotary magnetic position sensor can replace either absolute or incremental optical sensors, other magnetic and inductive technologies, potentiometers or magnetic switches.
