Fuze AR-MDH
for Mortar Ammunition
AR-MDH is a mechanical, nose, point-detonating fuze with super-quick action and distant arming. The fuze features highly sensitive impact mechanism and functions on solid ground, marshy ground and snow.
Fuze AR-MDH completes High-Explosive, Incendiary and Smoke mortar bombs of the following caliber:
· 60 mm
· 81 mm
· 120 mm
The fuze is supplied with safety cap, which has to be removed before firing.
The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions.
FUZE SAFETY
Before firing the Safety and Arm device prevents the detonator from positioning into the fire train. Even in case of unintentional ignition of the primer, no transfer of the firing pulse to the fire train can occur.
DISTANT ARMING
The fuze ensures distant arming of not less than 40 m from muzzle. At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line.
FUZE ACTION
Upon impact the fuze provides SQ action. The fuze functions upon impact on solid ground, marshy ground and snow.
