What is openSensor used for?
openSensor is used to detect when doors, windows, gates and other moving parts are opened and closed. Information about changes in status can be used for monitoring and automation.
How do you power openSensor?
openSensor should be powered by 5–48 V DC. Connect the brown wire to the positive (+) terminal and the green wire to the negative (GND) terminal.
How does openSensor detect a change in state?
openSensor detects a change in state using a magnet or a dedicated twinMagnet. Bringing the magnet closer to or moving it away from the sensor causes a change in its state, which allows it to detect the opening and closing of doors, windows, gates and other moving parts.
What is twinMagnet?
TwinMagnet is a dedicated accessory designed to work with the openSensor. It simplifies installation and ensures correct status detection. Alternatively, you can use a different magnet instead of the twinMagnet, provided its strength and method of attachment allow the sensor to function correctly.
How do the openSensor outputs work?
The openSensor has two open-collector outputs, which are shorted to earth (GND). One output indicates an open state, and the other a closed state. The maximum load current for each output is 50 mA.
How many states does openSensor distinguish?
openSensor distinguishes between two or three states, depending on the settings and the magnet used. With a single magnet, the open and closed states are detected. When using a twinMagnet, which consists of two magnets, it is possible to detect three window states:
Open – neither magnet is detected by the sensor;
Tilted – only one magnet is detected;
Closed – both magnets are detected.
