The SAM-SANT is a compact, Electro Mechanical Safety and Arming Mechanism designed for airborne payload applications, specifically for stand-off anti-tank missile systems. It serves as a critical safety interface between the missile and warhead, ensuring system safety during handling, transportation, storage, and launch. Upon receiving firing pulses from the Electronic Control Unit (ECU), the Arming and Detonation Mechanism (ADM) is activated via a rotor-based mechanism, enabling warhead initiation only under valid mission conditions. The system incorporates dual-redundant acceleration sensing (electrical and mechanical) for high reliability and built-in digital signal inputs for secure interfacing.

Operation Mode :
- Safe Mode:The system remains unarmed to prevent accidental detonation during handling, transport, or storage. Rotor mechanism physically isolates the firing train.
- Arm on Launch:The SAM arms automatically after detecting launch through acceleration and mechanical setback forces. The rotor aligns to arm the explosive path only when safe launch conditions are confirmed.
- ECU-Controlled Detonation:Detonation is initiated only after receiving a validated firing pulse from the ECU. This pulse is accepted only if all safety and arming interlocks are satisfied.
- Dual-Redundant Acceleration Sensing:Both electrical and electro-mechanical sensors must confirm acceleration/impact events to permit arming, ensuring fail-safe operation under high-dynamic conditions.
- Digital Input Configuration:SAM-SANT is integrated with 8 digital isolated inputs that allow mission-specific arming logic to be programmed through the control system interface.
Fuze Safety:
The SAM-SANT guarantees total fuze safety before launch. Even in cases of unintended primer ignition, no energy is transmitted to the firing train. The rotor mechanism and digital logic prevent accidental activation of the warhead.
Distant Arming:
The SAM-SANT is designed to arm only after missile launch, once it detects valid acceleration and setback forces. This ensures that the system remains completely safe during pre-launch operations and transitions to the armed state only after achieving a safe separation from the launch platform.
FUZE ACTION:
The mechanism functions by sensing acceleration and impact through dual-redundant systems. Detonation is enabled only under valid mission conditions, ensuring reliable operation upon target impact or other triggering scenarios as defined by the system logic.
