TECHNICAL SPECIFICATIONS
COMPATIBILITY
60 mm, 81 mm, 82 mm, 120mm and 160 mm mortar rounds, at all charges, muzzle and terminal velocities.
Expelling mode - for smoke, illuminating and cargo carrying rounds (as bomblets, AT or AP mines, SADARM, etc.)
Detonating mode - for HE and WP smoke rounds.
Replacement for: DM93, M776, EE81-W100.
W/adaptor: M84A1, FB338, M772, FH 55, FH81B.
OPERATION MODES:
Time delay, point detonating.
Electromechanical impact back-up.
TIME DELAY SETTING:
Manually operating (no tools required).
3.0 to 99.8 second x 0.1 second increments.
POINT EDETONATING:
Setatble, when 99.9 second setting is selected.
SETTING SYSTEM:
Digital setting.
Positive self-locking by three setting rings.
Unlimited setting storage time.
ACCURACY:
Better than 0.1seconds.
Standard deviation time delay, less than 0.1 second.
POWER SUPPLY
Air driven alternator.
ARMING:
By two environmental signatures:
Set back: Acceleration of 400 g minimum for 1 msec duration minimum.
Sustained air flow: 30 m/sec minimum.
Electronic arming: Only after T-4 seconds.
SAFETY:
Missequencing: Prevents arming whenever "set-back" arming conditions precedes 'air flow" arming conditions.
Arming Distance: 100 m from muzzle.
Double loading: the fuze willnot function in bore at a double loading event.
Shorted Electric Devices: the electric pyrotechnics are shorted until arming is completed.
Safety pull wire: No use of safety pull wire.
HUMAN ENGINEERING
The setting system, the push release buttons, and the marking are designed in accordance with human engineering requirements.
EXPLOSIVE OUTPUT:
Igniting/Expelling mode fuze: 3 gr of black powder
Detonating mode fuze: 7 gr of CH-6 booster pellet.
TEMPERATURE LIMITS
Operation: from -40c to +63c.
Storage: from -40c to +71c.
