Maintaining an internal core capacitance below 45 pF\/m prevents high-frequency data clipping, ensuring that factory eddy-current probe scaling metrics and piezo-velocity waveforms reach processing monitors without phase distortion. This controlled profile aids in stabilizing gap voltage validation (-10 VDC targets) during baseline static component calibrations. The mechanical interlocking stainless steel armor wrap blocks continuous rotor dynamics stresses and physical friction, while the structural design enforces high cross-talk suppression between parallel instrumentation runs laid out within the same heavy-industrial containment channels.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 84661-70 Armored Interconnect Cable Assembly (70 ft length)\u003c\/li\u003e\n\u003cli\u003e1 x Integrated 2-socket moisture-resistant female plug\u003c\/li\u003e\n\u003cli\u003e2 x Factory-crimped connection terminal ring lugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003ch3\u003eGrounding Rules\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTerminate the overall drain wire braid strictly at the instrumentation clean earth bus bar located within the remote monitor rack cabinet.\u003c\/li\u003e\n\u003cli\u003eDo not ground the stainless steel outer armor jacket at the machine housing frame boundary;
