1/ One of Ukraine's most-feared innovations is the Jonik magnetic-influence fuze, which is used to create proximity-activated booby traps. A Russian source describes in detail how it functions, warning: "do not move, do not touch, do not approach." ⬇️

2/ Writing on the Russian social media network VK, 'Warrior' describes how Ukraine uses Jonik fuzes against Russian soldiers:

3/ "Despite the fact that many fighters have heard about mined backpacks, first aid kits, drones and various IEDs, which detonate when picked up or approached, there are still frequent cases when another unpleasant incident occurs – a fighter shows interest in another object,…

4/ …which explodes during his study. And the matter lies in the electronic board of the initiation of an explosive device with non-contact target sensors.

Non-contact target sensors have been used in various mines for a long time.

5/ "However, such sensors were and are produced in fairly large dimensions from components of previous generations, being large in size and quite energy-intensive.

6/ "Today, when the enemy has access to modern power elements, to an unlimited number of cheap electronic components, the situation has changed, allowing the enemy to establish production of very light and compact electronic boards for initiating an explosive device…

7/ …with non-contact target sensors, which in specialised circles have received the common name "Jonik".

Jonik has quite small dimensions: its length is 6.5 cm, its height is 4 cm, and its width is 3 cm.

The operation of the Jonik is based on three target sensors:

8/ • Gyroscope – a sensor of angular orientation in space, responding to tilt;
• Accelerometer – a sensor of the speed of an object along one or more axes, responding to movement;
• Magnetometer – a sensor that responds to changes in the background magnetic field.

9/ "The Jonik operates using a 3 V power supply. An electric detonator, which is placed in the explosive mass, is connected to the terminals.

10/ "When any of the sensors is triggered (approaching a metal object, lifting or turning), an electric pulse is sent to the detonator and the charge is detonated.

Depending on the version of the Jonik, the board implements:

11/ • A long-range arming function – a timer that, after a certain period of time, switches the device to a working state and its target sensors begin to respond to changes in the external environment (this function is necessary so that the drone with the mine can…

12/ …fly to the drop point);

• A self-destruction function, responsible for detonation before the battery runs out.

Initially, the enemy used Jonik in PTM-3 mines instead of the standard VT-06 detonator.

13/ "Later, when the PTM-3 became smaller, the enemy started producing mine bodies that were externally similar to the PTM-3.

14/ "However, unlike the rather complex internal structure of the real PTM-3, the Ukrainian in his ersatz version [PTM-U] simply fills the body with explosives, installs a detonator with a connected Jonik and drops it from a copter.

15/ "And although such a mine is relatively safe for armoured fighting vehicles, for light wheeled motorcycles/automobiles and foot soldiers such a mine poses a serious threat.

16/ "In addition to ersatz copies of the PTM-3, due to its compact size, the Jonik is used to create various booby traps that look like various objects (for example, as if accidentally dropped radios, medical pouches, backpacks, abandoned boxes, etc.).

17/ "The enemy also installs a Jonik with a small explosive charge on many drones, with the expectation that if such a drone is shot down or falls, then when trying to approach it and pick it up, a detonation will occur.

18/ "The main threat of the Jonik is hidden in the sensitive magnetometer, which does not require any contact with a mine or mined object.

19/ "The magnetometer can provoke a detonation when a soldier (who has a large number of metal objects with him – a rifle, ammo, etc.) simply approaches the device with the Jonik.

20/ "In this case, the opposite action is also possible, when metal objects do not approach the Jonik, but on the contrary, if they move away.

21/ "For example, in recaptured or abandoned enemy positions, a rifle is found lying on a closed box; in the closed box there is an explosive device with a Jonik, which is visually impossible to detect.

22/ "The fighter, picking up the rifle and moving it away from the box, also changes the magnetic field, which affects the magnetometer of the Jonik, causing an explosion." /end
