NON-CONTACT FUSE FOR ANTI-TANK MINES NV-PTM-N

The non-contact fuse NV-PTM-N is designed for the anti-tank mines
TM-62M and TM-62P3. Using it, the mines are transformed from anti-track
into contact-less mines.
 
The fuse is a state-of-art, high tech device incorporating the latest
achievements of the technologies. It can be switched on automatically in case of
machine laying of the mines or manually. The control system of the mine is
activated after a time delay by mechanic and electronic clocks which allows
entirely secure walking away when laying it in operational position.
 
The electronic circuit controls different types of sensors (some of them
chosen as an option) and allows activation of the charge only when a tank passes
over it. Other transport vehicles as well as passages of tanks near and close to
the mine do not affect it. The activation of the fuse may happen after a chosen
number of tank’s passages over the mine between 0 and 10. This number is field
programmable before laying of the mine.
 
The fuse is resistant to electromagnetic mine exploders and the other
contemporary methods for mine-sweeping. It posses also anti-lifting action
against attempts for removal.
 
When the fuse is activated it’s EFP explodes forming a jet which penetrates
into the vehicle bottom and simultaneously performs detonations of the main
mine charge.
The fuse is resistant to electromagnetic mine exploders and the other
contemporary methods for mine-weeping. It posses also anti-lifting action against attempts for removal.
 
The technical data of the fuse are similar to those of NV-PTM but a
possibility for neutralization after the period of fighting state is implemented.
If not activated during the whole pre-set fighting state period, the control
system initiates the firing circuit for self-destruction of the mine or neutralize
the fuse according to the preliminary field-programmed mode - “neutralization“
or “self-destruction“ . The neutralized state of the fuse is clearly visualized.
