Buying Guide
Choosing the right magnetic contact is key for a secure home. These simple devices are your first line of defense. Let’s find the perfect one for you.
Types of Magnetic Contacts
Magnetic contacts come in different forms. You’ll find surface-mounted ones that attach to the frame and door. There are also recessed types that hide inside the door or frame for a cleaner look. Some are designed for heavy-duty use, like on garage doors.
Wired vs. Wireless
Wired contacts connect directly to your alarm system. They are very reliable and don’t need batteries. Wireless contacts offer easier installation and more placement flexibility. However, they do require battery changes.
Normally Closed (NC) vs. Normally Open (NO)
Most home security systems use Normally Closed (NC) contacts. This means the circuit is complete when the door or window is shut. When opened, the circuit breaks, triggering the alarm. Normally Open (NO) contacts do the opposite.
Sensing Distance
This is the maximum distance the magnet can be from the sensor for it to work. A larger sensing distance offers more flexibility in placement. For example, some contacts can work from over 1/2 inch or even 20mm apart.
Durability and Material
Consider where the contact will be placed. For outdoor or high-traffic areas, look for durable materials like metal zinc alloy. Many are also weather-resistant to withstand the elements.
Ease of Installation
Some contacts come with double-sided tape for quick mounting. Others might require screws. Recessed types can be more involved to install but offer a discreet appearance.
Compatibility
Ensure the magnetic contact works with your existing alarm system. Most wired contacts are universal, but it’s always good to check. Some are specifically designed for certain types of doors, like garage doors.
Additional Features
Some contacts offer adjustable brackets for better alignment. Others have a sleek design with hidden screws for a clean finish. Think about what features will best suit your needs.
I hope this guide helps you make an informed decision! Do you have any specific types of doors or windows in mind that you’d like to secure?
