There are two types of Hall effect sensors: the digital Hall effect sensor and the analogue Hall effect sensor.
Digital Hall Effect Sensor
The digital Hall Effect Sensor is primarily used to detect positional changes in various internal components of the printer. This ensures normal printer operation and supports the control of the motion system.
Analogue Hall-effect sensor
The analogue Hall-effect sensor is mainly used to monitor the speed and direction of rotation of the printer’s rotating parts. It helps to adjust the printer’s speed and precision, thereby contributing to ensuring high print quality.
