过孔式导电滑环是中心带孔的一系列导电滑环的统称，主要用于传输精密信号、微弱电流、大电流、高
电压；具有低扭矩，低损耗免维护；低电气噪音、超长寿命等主要特点；
     PSR-T100的无障碍过孔直径为101.6mm，外径为205mm；采用刷式接触技术多点接触保证接触稳定。低
压力，低摩擦，实现免维护免润滑超长使用寿命。
       任意通路数可选，最高通路数100通路。
      PSR-T100 is a commercial slip rings that with a 101.6mm through-bore and a 205mm outside diameter.
      Use fiber brush technology which offers several advantages over conventional slip ring contacts including
multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition
fiber bush do not require lubrication and produce virtually no wear debris
