The physical design features a molded right-angle two-socket electrical plug at the transducer termination end to provide a compact, low-profile connection within tight mechanical spaces, while the monitoring system termination end is fitted with standard terminal lugs for direct interface with I\/O chassis blocks. Optimized for low attenuation and high electromagnetic noise immunity, this 10.0 m (33 ft) cable assembly forms an essential signal pathway connecting Bently Nevada machinery protection monitors to structural vibration sensors, including those installed inside a 21128 Velocity Transducer Housing, ensuring accurate transmission of dynamic AC voltage signals without phase distortion or external environmental interference.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e-33: Cable Length Option\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e33 ft (10.0 m) nominal cable length.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e89477-33\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConductor Configuration\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTwo-conductor twisted pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConductor Gauge\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShielding Architecture\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOverall braided or foil shield with drain wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnector End A\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRight-angle, two-socket plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnector End B\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTerminal lugs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10.0 m (33 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMinimum Assembly Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.6 m (2.0 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum Assembly Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 m (99 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBently Nevada machinery monitors and 21128 Velocity Transducer Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eEngineering Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe twisted-pair geometry explicitly minimizes differential-mode noise induction, which is critical for preserving low-voltage AC velocity or acceleration signals across long processing runs.\u003c\/li\u003e\n\u003cli\u003eThe right-angle two-socket plug enforces a fixed mechanical orientation, reducing physical strain on the transducer connector pin assembly inside protective housing units.\u003c\/li\u003e\n\u003cli\u003eCalculated electrical properties of the 18 AWG conductors dictate specific capacitance limits per foot;
