Standard slip rings (T20HP)

T20HPDerived from the standard slip ring T13HP and designed with the same technology, the T20HP provides a solution for slip rings requiring extremely high performance, and offers multiplicity of power end signal channels.


The standard 30 ring slip ring assembly is mass produced and thus very competitive.
