The document introduces an angle sensor that uses touchless magnetic measurement technology and allows for transmissive measurements. Its features include an electrical range of up to 360°, simple mounting, lateral magnet offset of up to ±3 mm, IP67 protection class, single and redundant versions, unlimited mechanical lifetime, 12-bit resolution, independent linearity of ±0.5%, very favorable price/performance ratio, and an extremely flat design of 30x30x7mm³. The sensor utilizes the orientation of a magnetic field to determine the measurement angle, with a magnet attached to the rotating shaft and the magnetic field orientation captured by an integrated circuit. The calculated angle is represented by an analog output signal. The miniaturization of the sensor allows for application in small installation spaces. The housing is made of high-grade temperature-resistant plastic material and is completely sealed, making it insensitive to dust, dirt, or moisture. The two-part design of the RFA sensor series and its position marker offer maximum variability in mounting. The absence of a shaft and bearing makes the assembly insensitive to customer application tolerances. Measurements can be made transmissively through various non-magnetic materials. Electrical connection is made via lead wires.
