Magnetic Position Sensor Challenges Hall Effect Potentiometers

Delivering accuracy comparable to Hall-effect devices while offering higher reliability and better durability, the one-time programmable (OTP) RAME027 rotational absolute magnetic encoder displacement sensor provides an accuracy of ± 0.33 % at +25°C in a 27-mm form factor. The device works from a 5V (± 0.25 V) voltage supply and draws less than 20 mA at 5V. The device features a useful electrical angle of 360°, an analog output, a 12-bit resolution, and it works over a temperature range of -25°C to +85°C. Vishay can customize the device with user-specified mechanical dimensions, output SSIs, accuracy and resolution levels, reinforcements, and protection features against EMC and ESD. Vishay can also provide redundant functions and an extended temperature range. Samples and production quantities of the RAME027 are available now, with a lead time of 16 weeks for larger orders. Pricing starts at $211 each/50. For more tech and specs, peruse the RAME027 datasheet.
