    I’m hoping you knowlageable guys can help me,

    I’m using a washing machine motor to drive a lathe and have a speed controller all made up, the last thing I have to connect is the Speed sensor, My board has 3 output pins, +5v GND and sensor input.



    The hall sensor I have on my motor is a 2 wire sensor pictured below, Is this sensor going to be burned out if I connect +5v to one and Gnd to the other?

    Does anyone know of any similar two wire sensors online that might give me a clue, a datasheet for anything with 2 wires like this would help.

    Thats not a hall sensor its a tacho coil. The magnet on end of armature will produce an output from the coil, don’t think it’ll be any more than 5v though, normally in the milivolt range, best way to find out is connect a multimeter to it.

    I did try the multimeter, got milivolts turning by hand, can’t power it up without the controller, and the controller won’t ‘control’ without hall sensor input.

    It’s ok I’ll buy one, I’m not going to mess around building a filter and OP amp circuit for this.

    Thanks Seamy
