This specific configuration features a 3\/8-24 UNF threaded body, an unthreaded length of 0.0 inches (representing a fully threaded case), a 2.8-inch overall case length, and a 2.0-meter total cable length. It terminates with a miniature coaxial ClickLoc connector and is designed for standard electrical configurations where specialized hazardous area agency approvals are not required.\u003c\/p\u003e\n\u003cp\u003eWorking on the eddy-current operating principle, this probe measures static and dynamic distance between the probe tip and a conductive target, typically an AISI 4140 steel shaft. It interfaces directly with a 3300 XL extension cable and Proximitor sensor, providing a highly stable voltage output proportional to the gap. This setup is highly reliable for measuring shaft vibration, position, and speed in critical rotating machinery, including steam turbines, compressors, and high-speed pumps. The unarmored design offers excellent flexibility in protected machinery casings, and its standard FEP-insulated coaxial cable provides robust resistance against industrial fluids, oils, and moisture.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEddy-current non-contact measurement for machinery protection and condition
