This sensor is essentially a reed switch, encased in a plastic shell. Normally the reed switch is 'open' (no connection between the two wires). When the magnet is less than 13mm (0.5") away, the reed switch closes. They are often used to detect when a door is open, which is why they have mounting tabs and screws.
