The NV-PTM-2F is a non-contact fuse (works on a whole width of a target vehicle), designed to operate with anti-tank mines TM-62M and TM-62P3. The fuse combines the latest achievements in military industry electronics. NV-PTM-2F has two stage safety mechanism – electronic and mechanical, which guarantees reliability and safety not only during transportation and storage, but in preparation and arming process as well. The fuse is programmable by the programing device NV-PTM-2P. During programming, the following values could be set:
- Duration of the armed state;
- Target counter (targets to skip before activation);
- Sensors sensitivity level (according to local soil conditions and depth of laying);
- Electromagnetic signature duplicator resistance activation;
One programing device NV-PTM-2P is able to program unlimited numbers of fusses.
NV-PTM-2F fuse is equipped with a high-technology microprocessor system whit integrated seismic and magnetic sensors. The fuse is activated, only if presence of target vehicle above the mine is confirmed from both sensors. The fuse cannot be activated from passing humans or animals. NV-PTM-2F fuse has inbuilt anti-removal system.
