MS-K firewall connectors have met and are qual-

ified to the fireproof test of MIL-C-5015. This test

requires that a connector mounted to a firewall will

continure to operate for 5 minutes in case of fire and

prevent the passage of flame for 20 minutes. These

connectors are not environmentally sealed but oper-

ate

continuously

at

temperature

up

to

+177˚C

(+350˚F). MS-K connectors have crimp type con-

tacts; thermocouple contacts must be orderd sep-

arately and are solder type unless otherwise re-

quested on order. Cavities that will contain the

thermocouple contacts and contact material must

be specified when ordering.
