The \u003cstrong\u003e21504-16-32-10-62\u003c\/strong\u003e features an 8 mm tip constructed of polyphenylene sulfide (PPS), a high-performance plastic capable of withstanding harsh, wet, and chemical environments. It operates on the eddy current principle to sense static and dynamic distances between the probe tip and the observed target (typically an AISI 4140 steel target). This probe is designed without stainless steel lead armor (unarmored) and has a 3\/8-24 UNF-2A standard English thread. Unlike its armored sibling, the 21505, this unarmored variant utilizes a standard 95 ohm coaxial cable with a total length of 1.0 m (Option 10) and is equipped with a connector protector (Option 62) to prevent debris and moisture ingress at the connection point.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 mm tip diameter constructed of polyphenylene sulfide (PPS) for chemical, moisture, and corrosion resistance.\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF-2A threaded case with 1.6 inches unthreaded length and 3.2 inches overall case length.\u003c\/li\u003e\n  \u003cli\u003e1.0 m (39 inches) integral 95 ohm coaxial cable (Option 10) with miniature male coaxial connector and connector protector (Option 62).\u003c\/li\u003e\n  \u003cli\u003eUnarmored coaxial cable layout for routing in standard conduit and internal machine brackets.\u003c\/li\u003e\n  \u003cli\u003e80 mils (2.0 mm) linear measuring range when paired with a compatible 7200 Proximitor and target.\u003c\/li\u003e\n  \u003cli\u003eFrequency response from 0 Hz (DC) to 10 kHz (-5% at 10 kHz) for high-speed dynamic measurements.\u003c\/li\u003e\n  \u003cli\u003eOperational temperature range of -30 degF to +350 degF (-34 degC to +177 degC) for the probe tip and cable assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eShaft radial vibration monitoring for rotor dynamic analysis and bearing wear detection.\u003c\/li\u003e\n  \u003cli\u003eAxial thrust position measurement to monitor thrust bearing condition and prevent critical failures.\u003c\/li\u003e\n  \u003cli\u003eShaft average radial position determination for attitude angle and rotor stability checks.\u003c\/li\u003e\n  \u003cli\u003eRotor eccentricity and bow measurements during machine startup\/shutdown.\u003c\/li\u003e\n  \u003cli\u003eSpeed and phase reference (Keyphasor) sensing on steam turbines, gas turbines, compressors, pumps, and generators.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eOption Segment\u003c\/th\u003e\n      \u003cth\u003eCode on This SKU\u003c\/th\u003e\n      \u003cth\u003eDescription\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eOrderable Part Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e\u003cstrong\u003e21504-16-32-10-62\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e7200 Series 8 mm Standard Mount Proximity Probe\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eA -
