The types of detachers and anti-theft tags

UPD 07\02\2015

Here I will try to tell you about the specifics of detachers and anti-theft tags as well as their compatibility. Also I will give information about “marketing” and typical fraud of Chinese sellers.

AT the beginning of 2013 the situation was following:

When the business of anti-theft systems was emerged, the first anti-theft tags with locks of magnetic type were created. Later the capitalist system of business and marketing were inventing new ways to sell expensive anti-theft equipment to companies in order to justify their existence.

I will explain it further.

»Why do I need detachers if I can buy a neodymium magnet 100,000KG thrust?

A neodymium magnet is a piece of material with evenly distributed magnetic field. I mean all the magnetic power of this piece is distributed to all 360 degrees:

Unlike an ordinary magnet, detacher has severely deformed magnetic field thanks to its magnetic features. And all the magnetic power of the detacher is collected in a thin magnetic axis, and acts directly on the LOCK of an anti-theft tag:


Thus it turns out that whichever power or size an ordinary neodymium magnet has, it has no use at all. Besides magnet with very high degree of thrust costs about the same.

Click on the video to see that the ordinary magnet can open the sensor of the first generation, but doesn’t work with just a enhanced lock:

(“It’s a glove to protect fingers in case the detacher will hook magnet”)

There is one nuance… magnets (not detachers) stick on any metal very easily and strongly, and, as to my experience, I’ve heard dozens of occasions when magnet stuck to something in a store and because of it people had problems. As for detachers, the situation is much simpler due to the point orientation of the magnetic field.

Let’s talk about marketing ploys of detacher sellers and about the Chinese sellers.

There is a measure of magnetic capacity – the force of cohesion expressed in kilograms…

It can’t be applied to detachers at all.. because it is very difficult and technologically expensive to determine the degree of compression of the magnetic axis. In order to do this we should calculate the effective adhesion area between the detacher and the weight. Moreover we must calculate the ratio of materials. The result of this calculations is called Gausse(Gs).. Yes, it is a physical parameter. But it is extremely difficult to apply it mathematically. Therefore, all the measurements are standard: 12000, 15000, 6500.. In fact this is just marketing.

In our and in the manufacturers case it is Important… Can a magnet open the lock or NOT…

Here we come to the development of anti-theft tags. The tag or to put it more exactly, the Lock system of the tag is always made first.And only after a new more powerful detacher is made. And there’s no some specific parameters, the main thing if it works.

All the manufacturers of modern detachers – the Europeans, who have all the patents. But the Chinese don’t pay attention to any patents as usual and rivet cheap fakes. And they were first who started to use the Gauss measure(Gs) in order to that any client would be able to distinguish identically looking devices from one another through this measure.

Anti-Advertising of ordinary detachers:

The fate of any illicit dealer leads them to desire to spend less and earn more. And since a detacher is something inside the metal frame, therefore a dealer becomes more miserlier dealer.. instead of acceptably adequate detacher from even weak N33 material, these dealers put any stuff which is within the reach of the hand. It may be just a piece of magnet, or for example something like this:


Types of Anti-Theft tags and Magnetic detachers:

Magnetic Detacher Keychain — enhanced??? :

I can’t call It a detacher, because inside it there is a simple cylindrical neodymium magnet with 15mm diameter and 25mm height.

It works with the cheapest tags and with the cheapest locks. These sensors are used quite a lot. But all networks of shops gradually abandoned the use of non-amplified locks, because every pupil in that case will remove such magnet from water supply meter (or get it from the aquarium) and go to “hit” the shops. And such pupils are too much. So the use of weak tags were declined in Europe and the USA 10 years ago.

Works with the Sensors of the First Generation:

What’s INSIDE:

Three or Four balls, a Cup with holes to hold balls, Easily compressible coil spring…
all parts are made of metal which can be magnetized.


cheap shops, medium shops, any shops that still haven’t figured that they have time lag for 20 years. well, in the regions shops often do not care, because anti-theft companies in the regions have no knowledge at all in this field.


No. 1… Detacher with magnetic power similar to the Chinese pullers on 12000Gs. Ie the “standard enhanced”.


It’s possible to use it in 95% of the stores that don’t use SuperTag sensors.

Works with Sensors of the Second Generation:

What’s INSIDE:

Three or Four balls, a Cup with holes to hold balls, a Plastic Cup for fixing the Cup with balls, enhanced springs…
all parts are made of metal which is also magnetic.

This type tags OPEN:

ONLY with special enhanced detacher with a specific configuration of magnets. I MEAN there’s more magnets than one, magnetized in a special way and folded.


Chain stores… at the moment almost all the stores: Rebook, Nike and other sports.. Ostin, Zolla, and others… In general it can be applied in the most of the “branded” shops. Well, shops begin to use such sensors when they start to find unlocked tags in corners in a shop.


No. 2… Detachers with magnetic power similar to the Chinese pullers on 15-16000Gs.

Can open sensors: NEOTAG, Bomba and others with Hard-lock.

Works with the Sensors of the Third Generation:

What’s INSIDE:

Three or Four balls, Aluminum Cup with holes to hold balls, Aluminium Cup to hold the Cup with balls, enhances springs…
ONLY balls and SPRING are magnetic.

Can be OPENED:

ONLY with a special Hard-enhanced detacher with a specific configuration of magnets.
I.e is much more powerful enhanced detacher.

Not so rare as previously. RESERVED, H&M and a couple of networks are becoming to use them.
It is because the required detachers aren’t in wide use at present and Chinese counterparts can’t open tags with Hard-lock, because they are made by laying a ring on a ordinary enhanced detacher.
And since the ring gives the effect of keeping in the absence of magnetic field… the lock becomes far away from the reach of field. In this regard, rivals are starting selling Chinese junk. Well, let’s wish them good luck in catching up.


No. 3… Detacher No. 3 has no analogues except the official very rare detachers. Power is indicated symbolic 20000Gs.

Works with the Tags of the Fourth Generation:

1) DuralTag. Despite the manufacturer’s assurance that these tags can be opened only by the original detacher, which costs from 15,000 rubles.
2) rare round matte tags with paint inside and the words in purple “alerts” that clients usually meet in Western Europe (Belgium, UK).
3) Currently I have no information about NeoTags as these tags are rare and I don’t have them. I suppose this tags might handle the NeoTag. I look forward to the information.
(At the moment they aren’t promoted so much and it is better to keep silent so as not to tempt shop networks and other firms to start to use them.)
The Tags for the 4th generation are very expensive and they need an expensive detacher which not every shop network can afford.

DISTRIBUTION: Western Europe, (rare).



Датчики для которых Нет съемников в Открытой продаже:


Inside the tag cap can be placed RFID tag that can be detected on 13,56MHz frequency. It is used in some security systems through which you can keep track of such location sensor inside the dressing room. It may also be used in detecting tag on gate.
Comparing data … You can solve this problem without having to remove the tag… Fabric in case the primary tag is an RF!
Or AM jammers + RF fabric, if the primary tag AM.

  1. Было бы неплохо фотографии приложить к каждому описанию. Так было бы понятнее
