All shaft sensor inputs (other references Flow Sensor, Speed Sensor, Encoder and Feedback) are pinned alike.

Each time the Sensor is exposed to magnetic field (Hall effect) or metallic objects (Proximity) the circuit is closed between Pin-A and Pin-B. The controller sees this as 0 Volts, then 5 Volts when the sensor is clear of the magnet or metallic object.

Sensor Input Test
