What are metal detecting knife arches?
Metal detecting knife arches are a fantastic addition to your security structure. They are stand-alone structures that resemble a door frame. When a metal object passes through the arch, an alarm is activated consisting of an audible and a visual signal. The most common application for metal detecting knife arches is airport security, however they have many applications, including and not limited to sports events, schools, nightclubs, pubs and events companies. Due to their size metal detecting knife arches also serve as a visual deterrent for those who are carrying harmful metal items.
How does a metal detecting knife arch work?
Metal detecting knife arches typically use pulse induction technology. Sending a burst of current through a wire coil, creating a magnetic field. When a metal object passes through the magnetic field, a reflected magnetic field is created, triggering a reaction with the receiver coil. This activates the alarm systems.

Typically, a pulse indication metal detecting knife arch emits 100 pulses per second. However, depending on the make and model, this can range from 25pps to over 1000pps.

Metal detecting knife arches create a large magnetic field that covers the space inside the frame. If a person walks through with metal on their person, the alarm will be set off, informing security personnel that the person is carrying a potentially dangerous metal object.

Metal detecting knife arches with multiple zones can tell security personnel exactly where on the person metal is located. The more zones a metal detecting knife arch has, the more accurate it is.

Multi zone metal detecting knife arches contain multiple coils which create separate detection zones. Able to detect multiple objects and display all areas where metal can be found. The alarm lights on the legs of the unit highlight to security where metal is on a person.
