Description
8F51
and
8F526
circular filter connectors are
widely used in industrial, military and
aeronautical applications. They are suitable
for severe operating conditions.
They are intermeatable and interchangeable
as to the mounting with standard connectors
of the same series.
8AF51
and
8AF526
adaptors are the solution
to easily retrofit existing non filtered
<equipments.

The capacitance, insulation resistance and dielectric withstanding voltage are tested 100% on all contacts.
Note : • M filter is the most popular filter. If you require other filter types, indicate the maximum operating voltage, maximum capacitance and minimum attenuation
required at various frequencies.
• B filter is substancialy more expensive than other filters.
