Proximity Fuze

The ARCA 122 EPF is a high-precision, high-reliability proximity fuze developed for modern 122 mm artillery rockets. Equipped with advanced detection logic and mechanically adjustable proximity settings, it provides superior lethality and consistent performance in real battlefield conditions.

Technical Specifications

• Compatible Systems: 122 mm rocket warheads
• Arming Requirements: ≥ 20 G setback + ≥ 400 RPM spin
• Operating Temperature: –32 °C to +50 °C
• Storage Temperature: –54 °C to +71 °C
• Shelf Life: 10 years

KEY Advantages

Mechanically Adjustable Proximity Range:

The functioning height is manually adjustable between 8 m and 200 m, allowing mission-tailored effects against personnel, structures, and soft-skinned targets.

Robust Environmental & Shock Tolerance

Designed to withstand severe launch conditions of 122 mm rockets, including high vibration, temperature changes, and mechanical shock.

Fail-Safe Arming Mechanism

The fuze arms only when both conditions are met:

• ≥ 20 G setback
• ≥ 400 RPM spin

This ensures absolute safety during handling, storage, and transport.

Trigger Mode

Proximity Mode

Detonation occurs at the mechanically selected height (8–200 m) during approach to the target.
