MIL-DTL-46789D(AT)
handle to the corresponding specified torques. Measure the peak output voltage to verify that it
is not less than the specified value.
4.6.1.1 Electrical output (100% inspection) (not applicable to PIN 12282970 or
12918973). To determine conformance to 3.4.1 (condition D), each assembly shall be mounted
in the test fixture and connected with a 1.47 ±1% resistive load across the output terminals as
described in table I, condition D. The electric output shall be minimum 3.8 volts at peak and
1.1 volts, 50 ms later with a rotor shaft input torque not greater than 11.3 N-m applied
throughout the 150 ±5° shaft rotation (see 3.4.5).
4.6.1.2 Electrical output (100% inspection) for PINs 12282970 and 12918973. To
determine conformance to 3.4.1 each assembly shall be tested as per the appropriate assembly
drawing.
4.6.2 Operating position. To determine conformance to 3.4.2, the assembly shall be
mounted in the test fixture and subjected to the electrical output test of 4.6.1 at each specified
operating position.
4.6.3 Dielectric strength. To determine conformance to 3.4.3, perform the dielectric
strength test between the case and output leads in accordance with MIL-STD-202, Method 301
or equivalent (see 4.3.1), using 500 volts rms at a frequency of 60 Hz for a period of
60 ±5 seconds. During this test, verify that the assembly shows no evidence of loosening,
cracking, charring, or arcing.
4.6.4 Insulation resistance. To determine conformance to 3.4.4, measure the insulation
resistance between each conductor and case in accordance with MIL-STD-202, Method 302,
Test Condition B or equivalent (see 4.3.1). Verify that the resistance is not less than
100 megohms.
4.6.5 Rotation. To determine conformance to 3.4.5, the assembly shall be mounted in
the test fixture (see figure 1) or equivalent and the direction and angular rotation of the handle
shall be verified.
4.6.5.1 Torque and operating stability. To determine conformance to 3.4.6 and 3.4.7, the
assembly shall be mounted in the test fixture (see figure 1) and subjected to 10,000 cycles of
operation at the rate not in excess of 10 cycles per minute. Perform the test as follows:
a.
990 cycles at condition B
Not for assemblies
b.
10 cycles at condition H
12282970 and 12918973.
c.
Perform the electrical output test of 4.6.1
d.
Repeat for a total of 10,000 cycles
NOTE: For Assemblies 12282970 and 12918973, perform the tests per their respective
assembly drawing.
