Satel OMI-3 Optical-Magnetic Detector for Door/Window Opening Detection, 12V DC, NC Output, White

The Satel OMI-3 is a professional optical-magnetic detector designed for reliable door and window opening detection in alarm systems. Combining optical and magnetic sensing technologies, it ensures accurate and tamper-resistant monitoring. The detector features a normally closed (NC) alarm output and a built-in tamper switch for enclosure opening protection. With a compact surface-mount design and a 3-meter cable, it is easy to install in various residential and commercial security applications.

Advantages
