A metal detector gates, also known as a walkthrough metal detector, is a security device commonly used in airports, government buildings, prisons, and other high-security areas. Its purpose is to detect the presence of metal objects on a person passing through the gate. The technology behind a metal detector gate involves the use of electromagnetic fields and sensors to identify the metallic items.

Features:
A typical metal detector gate consists of two upright panels with metal detector coils embedded in them. These coils generate electromagnetic fields that extend from one panel to the other. When a person walks through the gate, any metallic objects on their body will disrupt the electromagnetic field, causing the gate to emit an alert signal.
The sensitivity of the metal detector gate can be adjusted to detect different sizes of metal objects. It can distinguish between harmless items like coins, jewelry, or belt buckles and potentially dangerous objects such as weapons or explosives. The gate’s design allows for a quick and non-invasive screening process, ensuring the safety and security of the premises.
Metal detector gates are equipped with advanced features to minimize false alarms. These include discrimination settings that filter out common non-threatening metals, like those found in clothing or medical implants. Additionally, modern metal detector gates often incorporate advanced imaging technologies, such as millimeter-wave scanning, to provide a clearer picture of the items concealed on a person’s body.
