Align HE50H22 RPM Sensor
This sensor is HALL type which senses RPM by motion of the rotating magnets. Usually 1 - 2 neodymium magnets are mounted on the fan of combustion helicopters with a Nitro motor.
1 Required modification
For usage with the Spirit units a small modification of the sensor cable is needed.
- Swap red and black wires in the connector - Align sensor has a unique colors.
- Crimp a new pin from the Servo connector.
- Wire layout
- White wire: RPM Output Signal
- Red wire: Ground
- Black wire: 3.3V - 8.4V
For this operation you will need a new servo connector and optionally a crimping plier.
For users that do not use a Spektrum satellites it should look in the following way:
If you are using Spektrum satellites, then instead of the Spektrum connector you will need second servo connector which can be powered from the BEC port. Make sure that the Black wire is in the middle of the Servo connector.
As the last operation, connect it to the unit.
2 Magnet mounting
We highly recommend to orientate each magnet as Active for a proper operation. More magnets will result in a higher reading resolution thus increased readout precision.
3 Governor Settings
When sensor is connected, please set the Sensor Divider parameter so that the value will represent count of the active magnets. Usually it is 1 or 2 magnets.
