No you don' have to.
Polarity marking is just sign of internal linkage.
All the pads of 'V' marking were internally linked, as all of 'A' are.
Sensor is same to the variable resistance as a view of circuit design engineer.

Hi, in the datasheet every sensor has an polarity marking. Do I have to pay attention to the polarity of the sensor and if yes why?
