ADI/WBOX Pro Window Door Contact Sensor - Roller Ball Plunger Type For Security Alarm Systems

About This Product

This is a standard roller ball/plunger-style door or window contact sensor, commonly used in professional and DIY security alarm systems (like ones from ADI or other brands that use the 'WBOX' style). Here's how it works: you mount one piece on the door/window frame and the other on the moving part. When the door opens, the plunger extends and breaks the circuit, triggering your alarm. It's a simple, reliable, and very common type of sensor. This one is brand new in its original packaging. Perfect if you're installing a new security system, expanding an existing one, or just need to replace a faulty contact. It's a basic building block for keeping your home or business secure. Check your system's compatibility to make sure this is the right style of contact for your panel. A must-have component for any security setup.
