Contact sensor DK-101 (magnetic contact sensor, reed switch)

Principle: work with the help of a magnet and a reed switch. When the magnet approaches, the contacts close.
Application: security alarms (opening doors/windows).

Pros: inexpensive, easy to install.
Cons: may trigger false alarms due to strong vibrations.

For installation on site, contact sensors have a standard M8 thread.
Both horizontal and vertical installation of the DK-101 contact sensor is possible.
