Magnetisk positionssensor udfodrer Hall-effekt enheder
Vishay Intertechnology lancerer ny magnetisk positionsensor, der udmærker sig ved en præcision som Hall-effekt enheder, men med højere pålidelighed og bedre holdbarhed (in english).
Vishay Intertechnology has introduced a new magnetic position sensor that delivers accuracy comparable to Hall effect devices while offering higher reliability and better durability. The one-time programmable (OTP) Vishay Sfernice RAME027 provides accuracy of ± 0.33 % at 25 °C in a small 27 mm 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 RAME027 make it the ideal solution for rough working conditions, including high vibration and shocks. Vishay can customize the RAME027 with customer-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.
The RAME027 works from a 5 V (± 0.25 V) voltage supply and draws < 20 mA at 5 V. The device features a useful electrical angle of 360°, an analog output, and 12-bit resolution, and it works over a temperature range of -25 °C to +85 °C.
