OFZ-2M is a mechanical, nose, point-detonating fuze with selectable super-quick or delayed action. The fuze has highly sensitive impact mechanism and functions on solid ground, marshy ground and snow.

 

 

The fuze completes High-Explosive, Incendiary and Smoke mortar bombs of the following caliber:

· 107 mm;

· 120 mm;

· 160 mm.

 

 The fuze is safe in storage, handling and operation and ensures the safe and reliable function of the ammunition in all weather conditions.

 

 

Operation Modes

The fuze has two operation modes, which are selectable, by built-in setter and wrench:

position “O”   for SQ action

position “З”   for delayed action 

 

 

Fuze Safety

Before firing the Safety and Arm device prevents the ignition primer 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.

 

 

Fuze arming

The fuze is armed within 5 to 20 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 or delayed action of 0.006 to 0.015 s.

The fuze functions under the impact and inertia forces. The inertia device ensures ignition not only upon impact on solid ground, but also on snow or marshy ground.
