What is DFMD?

A Door Frame Metal Detector (DFMD) as the name suggests is a metal detector fitted in a door to detect metal that may be hidden on the body of the person passing through this door.

DFMD or Door Frame Metal Detector, is a type of security equipment that is commonly used in various applications such as airports, government buildings, schools, and public events. It uses electromagnetic fields to detect metal objects on a person’s body, such as weapons or other prohibited items. DFMDs come in different sizes and designs to suit various security needs and can be installed at entrances or in walk-through gates. They are an important tool in ensuring public safety and preventing security threats.

The technology behind a Door Frame Metal Detector (DFMD) involves the use of electromagnetic fields to detect metal objects on a person’s body. The DFMD consists of two vertical panels that are placed on either side of an entrance, and emit low-frequency electromagnetic waves.

When a person walks through the entrance, any metal object on their body will disrupt the electromagnetic field, causing an alarm to be triggered. The DFMD is designed to detect various types of metal objects, including weapons and other prohibited items.

The DFMD technology typically uses pulse induction or very-low-frequency (VLF) technology. Pulse induction technology generates short bursts of magnetic fields that penetrate the body, while VLF technology uses continuous high-frequency magnetic fields.

Both technologies have their advantages and disadvantages, and the choice of technology may depend on the specific application and security requirements. DFMDs are an important tool in ensuring public safety and preventing security threats.

Application of DFMD, Door Frame Metal Detectors are:

1. Metal detectors are used for screening purpose in malls, hotels, buildings, railway station, metro,  airports, Schools,  and public events.

DFMD Gates Use

1. Aviation Industry – DFMDs are widely used in airports to screen passengers and their baggage for any metal objects, weapons, or explosives. They are installed at various checkpoints throughout the airport, including security checkpoints, baggage check-in, and boarding gates.

2. Defense Industry – DFMDs are used by defense agencies to protect their facilities and prevent unauthorized access by screening visitors and personnel for any metal objects or weapons.

3. Education Industry – DFMDs are used in schools and universities to ensure the safety of students and staff. They are often installed at entrances and can be used to screen visitors and students for any metal objects.

4. Event Industry – DFMDs are commonly used in large public events such as concerts, sports events, and political rallies to screen attendees for weapons or other prohibited items.

5. Manufacturing Industry – DFMDs are used in the manufacturing industry to prevent theft and unauthorized access to sensitive areas. They are installed at various checkpoints throughout the facility, including entrances, exits, and production lines.

6. Hospitality Industry – DFMDs are used in hotels and resorts to enhance security and prevent threats. They are installed at entrances and can be used to screen visitors and staff for any metal objects.

The use of DFMDs can vary depending on the industry and their specific security needs. They can be used to enhance security, prevent threats, and ensure the safety of personnel and visitors.

The benefits of using Door Frame Metal Detectors (DFMDs) in different applications can vary depending on the specific industry and security needs. Here are some of the general benefits of using DFMDs in different applications:
