*Critical Specifications in Chart showing Mercotac superiority

        Contact Resistance:  The extremely low contact resistance of Mercotac connectors allows them to transmit low voltage signals without distortion which is not possible with slip rings.

        Price:  Significantly lower cost of Mercotac units makes them usable in many applications where slip rings would be economically unfeasible.

        Maintenance:  Zero maintenance of Mercotac connectors reduces customer labor costs significantly, making them much more affordable than slip rings.

        Life Cycle:  The long life cycle of Mercotac connectors makes them more efficient and affordable than slip rings which need replacing much more often.

        RPM:  The higher RPM specification of Mercotac connectors allows them to be used in applications where slip rings will not work.
