GERMAN FUZES |
(28) B2 AND (28) B6 – ELECTRICAL IMPACT FUZE |
DATA: |
Bombs Used in: H.E. bombs. |
Color: Dark grey; yellow paint on shoulder. |
Material: Aluminum. |
Possible Actions: (a) Instantaneous. (b) 0.06 - 0.08 sec. delay. |
Principal Markings: |
El.A.Z. (28) B2. |
El.A.Z. (28) (B)2. |
El.A.Z. (28) B6. |
Secondary Markings: |
AA 1940 bmv 1940. |
AA 1941 bmv 1941. |
FC 1940 bmv 1942. |
c 1940 Rh.S. 1940. |
DESCRIPTION. Two firing circuits are employed in these fuzes, both charged through the B plunger. The impact switch closing the instantaneous firing circuit is an inertia bolt switch and operates only against resistance targets; i.e., upon deceleration of about 5,000 g. |
Safety switching is accomplished through depression of the A plunger, which switches off both arming circuits. (See fig. 162.) |
ARMING TIMES: |
Level Flight |
Diving
Flight (240 v.) |
||
Instantaneous: | 1.8 - 3.2 sec. | 1.4 - 2.2 sec. | |
Short delay: |
REMARKS. 1. Type 2 construction. 2. These fuzes have also been recovered with the charging condenser connected to the A plunger. 3. An inherent delay of about 0.01 se-cond is present in the instantaneous circuit. |
