The plastic PMN antipersonnel mine is replacing the older cardboard PMK-40 in the active inventory.
It is cylindrical in shape and resembles a large shoe polis can.
The casing of the mine is made of duroplastic and has a horizontal hole for the firing pin mechanism and primer charge.
The top half of the mine has a rubber mantle which is secured by a metal clamp.
The mine is actuated by pressure on the top of the case, which releases the spring-loaded striker, which hits the percussion cap capsule, setting off the main charge.

This mine was also adopted by the East German NVA, see
