8FLT-8FT-8FST-8FD
Description
Applications
MIL-C 38999 circular filter connectors are
widely used in military and aeronautical
applications. They are suitable for severe
operating conditions.
These connectors are based directly on
standard specifications :
They are intermeatable and interchangeable
as to the mounting with standard connectors
of the same series.
