Different materials of EAS Pedestal
EAS Pedestal mainly has the following materials. Different materials determine different appearances and prices.
Aluminum alloy EAS Pedestal
Aluminum alloy is the most widely used non-ferrous metal structural material in the industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries.Aluminum alloy has low density, but relatively high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, second only to steel.Aluminum alloy is also widely used in EAS pedestal because of its low density and light weight.But because the material of aluminum alloy is relatively thin, sometimes the host of the antenna must be external.In addition, due to its light weight, it is relatively easy to transport.Let's take a look at what an aluminum alloy antenna looks like.
ABS EAS Pedestal
ABS is one of the five synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, and good surface gloss. It is easy to paint. , Coloring, can also be surface sprayed metal, electroplating, welding, hot pressing and bonding and other secondary processing, widely used in machinery, automobiles, electronic appliances, instrumentation, textile and construction and other industrial fields, is a very useful Wide range of thermoplastic engineering plastics.ABS can also be used in EAS pedestal systems,the density of ABS is also relatively light,so it is also easier to transport.Let's take a look at some EAS antennas made of ABS.
Acrylic EAS Pedestal
Acrylic characteristics
1. It has crystal-like transparency, light transmittance of 92% or more, soft light and clear vision. Acrylic colored with dye has a good color development effect.
2. Acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.
3. Acrylic sheet has good processing performance, which can be thermo formed or mechanically processed.
4. The transparent acrylic sheet has a light transmittance comparable to that of glass, but the density is only half of that of glass. In addition, it is not as fragile as glass, and even if broken, it will not form sharp fragments like glass.
5. The abrasion resistance of acrylic sheet is close to that of aluminum, with good stability and resistance to various chemicals.
6. Acrylic board has good print ability and spray ability. Adequate printing and spraying process can give acrylic products ideal surface decoration effect.
7. Flame resistance: It is not spontaneously flammable, but it is flammable and does not have self-extinguishing properties.
Acrylic is also popular in the EAS industry for its beautiful appearance and good performance.Here are some examples of acrylic EAS antennas.But because of the high density of acrylic, the weight is relatively heavy, and the transportation cost will be relatively high.
In short, the material of aluminum alloy and ABS is relatively light, and the transportation cost is similar, while the weight of acrylic is relatively large, so the transportation cost is relatively high.
At present, these three materials are mainly composed of EAS pedestal.In the past, there were some RF antennas made of steel, but in recent years, these antennas have been gradually eliminated because of the heavy weight of steel, high transportation costs, and affect the detection frequency of the antenna.Let's look at some case examples of these EAS antennas of different materials.

BH9677 AM ABS antenna for shopping mall anti-theft
BH9686 AM Acrylic antenna for clothing store anti-theft
EAS system circuit board
Regardless of whether it is aluminum alloy, ABS or acrylic, it is just the material of the shell, the circuit board inside is the same.
Regarding the circuit board, Bohang has its own characteristics, developed and produced by itself. Its biggest feature is that it is easy to install and debug, only need a screwdriver to solve the debugging problem, without the need for an external host.
Bohang professional technical personnel research and development
The circuit board only belongs to Bohang
Factors determining EAS antenna quality
There are too many eas series products on the market, including many original products and imitation types.All prices and quality are closely related.Several factors that determine the quality of an EAS antenna include the detection distance, false alarm rate, sensitivity, and service life of the antenna,etc.
If you want a set of EAS antennas with good performance, it needs good quality shell materials and high-performance circuit boards.
