The TS-50 is a 90 mm (3.5 in) diameter circular Italian blast resistant minimum metal anti-personnel mine designed and produced by Valsella Meccanotecnica (Italy).
The mine requires a constant pressure of approximately 2 to 5 kg (5 to 11 lbs) for an average of 0.11 seconds before the fuze will detonate.
This feature, combined with the use of non-magnetic metals used in the mine, make it difficult to clear using conventional techniques.
The mine was originally produced by Tecnovar italiana SpA, and was in service with the Italian army.
Uncleared minefields containing TS-50 mines are located in Afghanistan, Azerbaijan, Ecuador, Georgia, Kurdistan, Kuwait, Iraq, Lebanon, Rwanda and the Western Sahara.
