This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is ‘open’ (no connection between the two wires). The other half is a permanent magnet. When the magnet is less than 10mm away, the reed switch closes. They’re often used to detect when a door or drawer is open, which is why they have mounting tabs and screws. This sensor/magnet pair can be secured in place with double-sided foam tape.
