TM-62 series of mines

TM-62 is the designation for a series of Soviet anti-tank blast mines. The mines have a central fuze and typically have a explosive charge, however they vary greatly in detail. The mines can be laid manually or automatically from a mine laying machine including the PMR-1, PMR-2 wheeled towed mine layers, the GMZ tracked mine laying vehicle and the VMR-2 helicopter mine laying system.
In a static test, the TM-62M proved capable of penetrating the hull of a Centurion tank, killing the simulated crew of animals inside.
The TM-62 series of mines can be fitted with the same fuzes as the TM-72 series of mines, which include MVN-72 and MVN-80 fuzes which are vibration and magnetism sensitive.
Fuzes.
"Note: magnetic influence fuzes give full-width attack i.e. any part of the target vehicle passing over the mine will trigger detonation, not just the track or wheels. However, since magnetic fuzes are electronic, their operational life relies on battery power. Ultimately the battery will run down, after which the mine no longer functions. In contrast, a purely mechanical fuze (usually triggered via a belleville spring) gives a much longer operational life e.g. mines planted 50 years previously will still detonate if a target vehicle drives over them."
