Mortar Electronic Reshef Fuzes
ResheFuse MR 797
Mortar Electronic Point Detonating Time Fuze
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
