ECP 134-55 Contact Ring

The contact rings shown here are fabricated from finger
stock. These rings can be formed in any diameter
containing an integral number of fingers, down to the
minimum diameter to which that particular strip can be
curled. This limit is spelled out in the tables of
specifications under “MIN OD”.
Another specification of importance in the case of
contact rings is indicated on the table as dimension “E”,
the “recommended mounting dimension”. This figure
provides for the proper amount of compression against
the “plug” to assure a good contact. It should be added
that many variations of these rings are possible. Full
information on custom forming is available on request
