This specific configuration distinguishes itself from standard configurations by integrating a zero unthreaded length (0.0 inches), a compact 1.2-inch threaded case, and a 2.0-meter total cable length. Critically, it features a specialized \u003cstrong\u003eFluidLoc cable\u003c\/strong\u003e option (-12) that prevents oil, moisture, and other process liquids from migrating through the internal structure of the cable, making it ideal for highly demanding rotating machinery environments where housing sealing is paramount. It is supplied with the \u003cstrong\u003e-CN suffix\u003c\/strong\u003e, indicating compliance with China's strict hazardous area certification standards including NEPSI and CCC.\u003c\/p\u003e\n\n\u003cp\u003eOperating as a key component of the 3300 XL 8 mm Proximity Transducer System, this sensor works on the eddy current principle to provide highly accurate displacement signals. When paired with a 3300 XL Proximitor sensor and an appropriate extension cable, the system delivers a linear output voltage directly proportional to the distance between the probe tip and the observed conductive target, such as an AISI 4140 steel shaft. The unarmored design allows for convenient installation within protection conduit or internal bearing housings, providing crucial predictive maintenance data for critical rotating
