LPZ mine
From Wikipedia, the free encyclopedia
The L.P.Z. mine or Leichte Panzermine (Light tank-mine) was a circular metal cased German anti-tank mine produced during the Second World War. The mine was accepted into service in 1941[1],and were intended for use by Paratroops. Production of the mine ended in 1942 with only 31,700 mines produced[2]. The mines were first used during Operation Merkur, the airborne invasion of Crete and were still in use at the end of the war.
The mine is circular and has a very rounded appearance, with a central metal cap that covers the mine's safety device, a large screw. The mine is unusual in that it uses five igniter/fuzes linked to a central detonator by a series of flame tubes. Sufficient pressure on the top surface of the mine causes it to press down on one or more of the igniters compressing a spring and allowing two steel striker retaining balls to escape releasing the striker, which is forced upwards by a second spring. The striker hits a percussion cap at the top of the igniter, the flash from which travels along a flame tube to a metal chamber in the centre of the mine. If the safety screw is removed then the flash is free to ignite the detonator, which in turn detonates the main charge.
