Mortar Electronic Reshef Fuzes

ResheFuse MR 797

Mortar Electronic Point Detonating Time Fuze

The MR797 is an Electronic Point Detonating Fuze that is widely compatible with all calibers. This reliable fuze requires no safety pull wire and meets all safety requirements.

TECHNICAL SPECIFICATIONS

To be used with all types of HE mortar bombs with calibers of: 60mm, 81mm, 82mm and 120mm.

Operated by switch Point detonating (PD): Detonates warhead on impact with target. Delay: Detonates warhead after 50 milliseconds from impact with target.

Air driven alternator.

By two arming mechanisms: Set back: Acceleration of 400g minimum, for a duration of 1 millisecond minimum. Air Speed: of 30 m/s minimum.

Miss-sequencing: Prevents arming the fuze whenever arming condition of “air flow” precedes arming condition of “set back”. Arming distance: 70m minimum from muzzle. Double loading: The fuze will not function in bore in at double loading event. Shorted electric detonator: The electric detonator is shortened until arming. Safety pull wire: No use of safety pull wire.

Booster pellet: 7g CH-6.

Firing: From -40°c to +63°c Storage: From -46°c to +71°c

Total length: 95.1mm Cross section diameter: 51.1mm Intusion depth: 27.5mm Thread size: 1.5″-12UNF-1A Weight: 0.3kg

MIL-STD-331: Environmental and performance tests for fuze and fuze components. MIL-STD-333: Fuze, projectile and accessory contours. MIL-STD-1316: Fuze design, safety criteria. STANAG 4187: Fuzing system – safety design requirements.
