This integrated setup couples a 3300 XL 8 mm probe and a 3300 XL Proximitor sensor within a single, machine-mounted polyphenylene sulfide (PPS) housing. This engineering approach eliminates the need for external extension cables and standalone Proximitor enclosures, allowing field wiring to run directly from the housing to the monitoring system.\u003c\/p\u003e\n\n\u003cp\u003eFor precise mechanical adjustment and alignment, this variant features a 40 mm standoff adapter (Option 04) and a 70 mm probe penetration length (Option 70). Environmental integrity is maintained by the glass-and-conductive-fiber-reinforced PPS body, which effectively dissipates electrostatic charges and is rated for IP66 and NEMA Type 4X environments. This specific metric configuration is supplied with one M20 fitting and two blanking plugs (Option 03) for electrical conduit entry, and utilizes a 3\/4-14 NPT thread (Option 02) for secure mounting to the machine casing.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Assembly Design\u003c\/strong\u003e: Combines a 3300 XL 8 mm probe and Proximitor sensor inside a single enclosure, eliminating separate extension cables and dedicated remote transmitter housings.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMultiple Hazardous Area Approvals\u003c\/strong\u003e: Option BR (the designator corresponding to Option 28 in Bently Nevada metric documentation) certifies the assembly for ATEX, IECEx, and CSA hazardous area classifications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Depth\u003c\/strong\u003e: Includes a 70 mm probe penetration sleeve (Option 70) and a 40 mm standoff adapter (Option 04) for precise positioning of the sensor tip.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant PPS Housing\u003c\/strong\u003e: Molded thermoplastic reinforced with glass and conductive fibers provides robust chemical, UV, and impact resistance alongside electrostatic dissipation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP66 and Type 4X Ratings\u003c\/strong\u003e: Engineered for direct machine mounting in severe industrial environments, offering high protection against moisture, dust, and washdowns.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecure Conduit Entries\u003c\/strong\u003e: Includes one M20 connection fitting and two plugs (Option 03) to prevent environmental ingress at the cable entry ports.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe system is used for continuous, non-contact shaft vibration and axial position measurements in rotating machinery.
