High reliability magnetic position sensor delivers accuracy comparable to Hall effect devices

Vishay Intertechnology has a new magnetic position sensor that delivers accuracy comparable to Hall effect devices while offering higher reliability and better durability. The OTP Vishay Sfernice RAME027 provides accuracy of ± 0.33% at 25C in a small 27mm form factor. Typical applications will include military and industrial joysticks, electrical actuators, machine tools, textile manufacturing, milling, and robotics. The robust capabilities and construction of the device make it the ideal solution for rough working conditions, including high vibration and shocks. The company can customize the device with customer-specified mechanical dimensions, output SSIs, accuracy and resolution levels, reinforcements, and protection features against EMC and ESD. They can also provide redundant functions and an extended temperature range. The device works from a 5V (± 0.25V) voltage supply and draws <20mA at 5V. The device features a useful electrical angle of 360-degrees, an analog output, and 12-bit resolution, and it works over a temperature range of -25C to +85C.
