What type of feedback positionaing can micro actuators have

Micro actuators can have various types of feedback positioning including encoder feedback, potentiometer feedback, capacitive feedback, inductive feedback, and hall-effect sensor feedback. These types of feedback positioning provide information about the position or motion of the micro actuator, allowing for precise control and improved performance.

The FIRGELLI Micro Pen Actuator model FA-BS16-4-12-xx comes with built in Hall sensor feedback. This type of feedback offers extremely high degrees of precision capabilties, as they produce 360PPR (pulses per revolution). This equates to about 1 micron of control. These actuators are therefore suitable for any number of applications including medical devices where high degrees of control are needed. 

How do you wire up a Micro Actuator

Wiring of these Micro Actuators is pretty easy. There will be 2 wires for the motor, where reveering polarity to a power source (usually 12v) will change direction of the actuator. The other 4 wires are for the feedback hall sensor. A wiring diagram is show below for the FIRGELLI Micro Actuator.
