I am about to select a hall effect sensor. Two types are available: one has an open collector (OC) output, the other an RC output. The datasheet states that both are current sinking. But because I neither know what the RC output is (at least I am not sure) nor how it works, I am not able to select one.
My question is about the RC output. Does RC stand for resistor / capacitor to create the output signal? If so, how does it work? My guess would be, that the resistance or capacitance are modified to create a varying output signal.
Because I have to choose between the OC / RC output type I would like to know the advantages of the RC output type. The datasheet only mentions:
If there is stronger electromagetic interference or the distance between sensor and the measuring instrument is farther, an OC output (open collector) is suggested to use.
Why should I choose the RC output type?
