The non-contact fuse NV-PTM-C is designed for the anti-tank mines
TM-62M and TM-62P3.
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.
After the preset fightihg condition period the electron block activates the
firing circuit for the mine self-destruction or neutralization. The state of
neutralization is visualized by the nozzle unfloading.
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 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.
