Linear Actuator Hall Sensor Feedback: When Do You Need It?
A Hall sensor actuator outputs pulses while the motor rotates. The controller can count those pulses to estimate travel position. This is useful when a project needs more repeatable movement than a simple extend/retract switch.
| Requirement | Feedback Need |
|---|---|
| Simple open/close movement | Usually no feedback |
| Preset position control | Hall sensor or potentiometer recommended |
| Synchronized dual actuators | Feedback strongly recommended |
| Medical or care equipment | Confirm feedback, duty cycle, noise, and safety margin |
Hall sensor vs potentiometer
Hall sensors provide pulse feedback. Potentiometers provide analog position feedback. The right option depends on the controller, accuracy expectation, stroke length, and working environment.
RFQ details to confirm
- Controller input type
- Pulse count or signal requirement
- Stroke length and speed
- Single or synchronized actuator system
- Noise and duty cycle requirements
