M20 AND M20A1 SENSING ELEMENT PROXIMITY FUZE

Figure 1-15.—Mk 43 Mod 0 target detecting device. The fuze circuitry produces a lobe pattern. It radiates a pattern at right angles (fig. 1-16) to the longitudinal axis of the weapon. When the Mk 43 is initiated by the conventional method, fuze functioning occurs instantaneously when a firing pulse is received from the thermal battery. If the alternate method is used (striker rod), the fuze is set for either of the two functioning delays—DLY 1 for 0.015-second delay or DLY 2 for 0.100-second delay. Detonation of the bomb is delayed by either 0.015 second or 0.100 second, depending on the delay that is selected. Figure 1-16.—Mk 43 Mod 0 target detecting device antenna pattern.
