Hall Effect Sensor
A non-contact position sensor based on the Hall effect principle that calculates position by detecting changes in a magnetic field. It has no wearing parts, and when used in joysticks it can fundamentally prevent drift.
Timeline (last 90 days)
The working principle of a magnetic encoder is to mount a permanent magnet on a rotating shaft, paired with a Hall-effect sensor chip fixed on a circuit board that detects changes in magnetic field direction to calculate the shaft's angle
Current sensors typically use one of two approaches: Hall-effect sensors (such as the ACS712 series) or low-resistance shunt resistors paired with operational amplifiers.
Hall-effect sensors do not require cutting the circuit and offer good isolation, making them suitable for sharing a single detection point across multiple servos; shunt resistors are lower in cost but require attention to common-ground issues.
Hall effect sensors trigger signals by detecting magnet displacement without requiring traditional metal contact structures, enabling more extreme thinness and supporting fully customizable actuation points across the entire key travel.
