The vibration detector is inclosed in a small plastic cylinder. The internal components are not known but probably are a heavy mass (inertial) coupled to an electric transducer. The am- plifer and the relay are contained in a small plastic box.
The sensitivity of the fuze depends on the type of terrain in which it is buried. When placed on the floor of a room, it allegedly records footsteps 10 meters distant. It is used with a proximity type mine.
No information about functioning.
Nothing else to see.
