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 magnet. When the magnet is less than 18mm (~0.8") away, the reed switch closes. They’re used to detect when a door or drawer is open, which is why they have mounting tabs and screws. Typically as door and window contacts which fit all your home security needs. Door and window contacts work with a sensor and a magnet. The sensor is placed on the frame of the door or window, while the magnet is placed on the door or window itself. This creates a circuit between the two. However, when the circuit is broken by opening up the window or door, a signal is sent to the alarm control panel that an entry has been breached.
