Door Sensors / Magnetic Contacts

Door Sensors / Magnetic Contacts are essential intrusion detection devices used to monitor the opening and closing of doors, windows, and access points. They work on a simple magnetic principle—when the door opens, the magnetic circuit breaks and triggers an alert. These sensors are widely used in residential, commercial, and industrial security systems for enhanced perimeter protection. Designed for reliability and durability, magnetic contacts integrate seamlessly with burglar alarms, access control, and building management systems. They offer fast response, low false alarms, and long service life, making them a cost-effective solution for safeguarding premises.
