MIL-PRF-8805/2K
Dielectric withstanding voltage:
Sea level: 1000 V rms.
Altitude: (50,000 feet):
MS25085-1 through 12: 400 volts.
MS25085-13: Not applicable.
Contact bounce:
MS25085-1 through 12: Not applicable.
MS25085-13: 3 milliseconds maximum.
Intermediate current: Not applicable.
Low level circuit:
MS25085-1, MS25085-2, MS25085-6, and MS25085-13: Not applicable.
MS25085-7 through MS25085-12: 50,000 cycles.
Electronic logic circuit (5.0 V dc, .010 amperes):
MS25085-1, MS25085-2, MS25085-6, and MS25085-13: Not applicable.
MS25085-7 through MS25085-12: 50,000 cycles at an actuation rate of 120 cycles per minute
maximum with no "stick", or "misses", allowed when tested in accordance with ANSI/EIA RS448,
method 17 as follows:
Test condition:
Each pair of switch contacts shall be tested using a 5.0 ±0.5 V dc, 10 ±1 mA resistive load.
During each closure of the contacts, the voltage drop across the switch terminals shall be
monitored for a duration of no less than 50 percent of each contact static closure. The
switch contacts need not be monitored until 10 milliseconds after the initial contact closure
to exclude any contact bounce. During each opening of the contacts, the voltage drop
across the switch terminals shall be monitored for a duration of no less than 50 percent of
each contact opening.
A voltage of 2.1 volts or greater across the switch terminals shall constitute a contact "miss"
(failure to properly close the circuit). A voltage drop of less than 90 percent of the
open-circuit voltage shall constitute a contact "stick" (failure to properly open the circuit).
The monitoring device shall either record the number of contact closures at which "sticks"
and "misses" occur, or discontinue the test when "sticks" and "misses" occur.
Operating temperature:
a. 25 percent of the test cycle at the minimum temperature specified.
b. 25 percent of the test at room ambient conditions.
c. 50 percent of the test cycles at the maximum temperature specified
Mechanical endurance:
MS25085-1, MS25085-2, and MS25085-13: 100,000 cycles, at .005 (+.002, -.001) inch overtravel.
MS25085-6 through MS25085-12: 100,000 cycles, at full overtravel.
Electrical endurance (power circuits): 25,000 cycles.
