** Service Rating is comparable to MS rating A. Miniature connectors rated Service Rating I will provide a minimum flashover
voltage at sea level of 2,000 volts AC (RMS). Service Rating II is comparable to MS Service Rating D, and will provide a
minimum flashover voltage of 2,800 volts AC (RMS) at sea level.
Please note that the electrical data given is not an establishment of electrical safety factors. This is left entirely in the
designer’s hands, as he can best determine which peak voltage, switching surges, transients, etc. can be expected in a
particular circuit.
OPERATING TEMPERATURE RANGE
–65°C (–85°F) to 200°C (392°F)
ENVIRONMENTAL SEAL
Wired, mated connectors with the specified accessory
attached will meet the altitude immersion test specified in
MIL-C-26482.
DURABILITY
Minimum of 500 mating cycles.
SHOCK AND VIBRATION REQUIREMENTS
When tested as follows, the connector shall sustain no
physical damage, or electrical discontinuity exceeding
one microsecond.
SHOCK:
Pulse of an approximate half sine wave of 300g magnitude
with duration of 3 milliseconds applied in three axes.
VIBRATION:
Sixteen hours of random vibration having a range of 50 to
2,000 Hz with a 41.7G peak level.
