PMN is a pressure-operated Anti-Personnel (AP) blast mine introduced into service in the early 1960s. The mine has a Bakelite body with a flat rubber pressure plate, reinforced by a Bakelite disc and secured around the body by a thin metal band. The fuze runs transversely through the mine body, with the arming delay mechanism and arming pin protruding from one side and the detonator plug from the other. The spring-loaded steel striker is retained in one half of the mine by the arming pin, immediately opposite the MD-9 stab-sensitive detonator and booster assembly. The main charge is cast into the cavities surrounding the fuze mechanism. A central spring-loaded plunger has a slotted aperture with a step to retain the striker, once the mine is armed. The body of the PMN is normally the brown colour of unpainted Bakelite, with a black rubber pressure plate. Markings are stencilled in black on the base, and in yellow on the pressure plate.
