This design integrates a 3300 XL 8 mm proximity probe and its matching 1-metre Proximitor sensor directly into a single, robust housing cover. By consolidating these components, the assembly eliminates the need for separate extension cables and dedicated Proximitor housings. The field wiring connects directly inside the terminal compartment of the transducer housing, significantly simplifying system design, decreasing connector-related signal losses, and reducing overall installation costs.\u003c\/p\u003e\n\n\u003cp\u003eThis configuration is built with an Option 038 probe penetration length of 3.8 inches (97 mm) and is supplied under Option 00 (no conduit fittings; includes two sleeve plugs and two washers). It utilizes Option 02, providing a 3\/4-14 NPT outer sleeve mounting thread to secure the unit to the machinery casing. The housing itself is molded from a high-durability, UV-resistant, glass-reinforced polyphenylene sulfide (PPS) thermoplastic embedded with conductive fibers to dissipate static charges. Sibling configurations within this family vary by offering metric mounting threads, different standoff adapter lengths, or pre-packaged conduit fittings, making this specific English-threaded, 3.8-inch penetration unit the ideal configuration for standardized medium-depth machine cases.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOption 28 Probe
