MAGNETIC ANGLE SENSORS: RESOLUTION EXPLAINED
Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders (a device providing the angle of a magnet attached to a mechanical shaft, under a digital form). Resolution is a key parameter since it indicates the smallest angle that the sensor is capable of resolving. Unfortunately, when comparing products, users may often be misled, as...
ANGLE SENSOR USE CASE: E-BIKE
In this use case, we will examine the application of MagAlpha Angle Sensors in e-bikes. MagAlpha sensors can be used to detect cadence and inform the motor on how much power is needed to assist the cyclist in various scenarios. E-bikes rely on sensors to inform the motor when power is required to assist the cyclist. Cadence sensors measure how quickly the cyclist is pedaling. MagAlpha sensors ...
OPTIMIZING HAPTIC HMIS FOR RELIABILITY WITH MAGNETIC SENSORS
Rotary dials are used in diverse applications for human-machine interfaces (HMI). Touch interfaces include the buttons, knobs, and dials on everyday devices, from automobiles and white goods, to the touch screen on your mobile phone. These devices not only translate human input into an electrical signal, but they also provide an important feature — haptic feedback. This is especially useful for sa...
