The Hall effect sensor usage today: The produced output voltage typically is in the range of milli volts (mV) and is additionally amplified by integrated electronics, fitted inside of the sensor housing. The sensor will then have one positive and one negative side and create a voltage, known as Hall voltage. When the hall sensor is put in a magnetic field the electrons running through will move to one side of the sensor. For that reason, to eliminate the external influences, the signal wires from the sensor to the control unit are usually shielded with a coaxial coated wires type of protection. Also, this operation can be performed and when the connector of the sensor is plugged in. The RPM sensors typically can be Hall or inductive type. Hall-effect sensors are used for proximity sensing, positioning, speed detection, and current sensing applications.
