Mortar Electronic Reshef Fuzes
ResheFuze MR787
Mortar Electronic Proximity Fuze
The MR787 is a Radio Proximity fuze that is widely compatible
with all calibers. This safe, reliable product has a delayed
transmission. Utilizing the Doppler Effect, the fuze is designed
to initiate the warhead at the optimum height above the target
providing maximum effectiveness of the mortar ammunition.
TECHNICAL SPECIFICATIONS
To be used with all types of HE mortar bombs, with calibers of: 60mm, 81mm, 82mm and 120mm.
Operated by switch Proximity (PRX): Detonates warhead at optimal height above target. Point Detonation (PD): Detonates warhead upon impact with target.
Air driven alternator.
By two arming mechanisms: Set back force: Acceleration of 400g minimum, for 1 m/sec duration minimum. Sustained air flow: 30 m/sec minimum.
Mis-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 at a 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: 95.5mm 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.
PRX Mode (standard factory set)- 2.5 above target for 60/81/82mm. 4.0m above target for 120mm. Other heights of burst upon request.
