When replacing an older version of this assembly, verify that the sleeve depth (-041 in this specific code) matches the existing casing insertion length to avoid either mechanical contact with the target shaft or an out-of-range sensor gap.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eMoisture accumulation is a common issue in humid, coastal, or high-condensation environments. If the conduit routing is not installed with a low-point drain loop (drip leg), water can accumulate inside the housing, causing early failure of the probe-to-extension cable connection. Ensure all threaded joints are properly sealed with industrial-grade thread sealant to preserve the NEMA 4X rating.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eBefore completing the physical installation, ensure the internal probe cable has a service loop. This loop prevents strain on the coaxial connector when the probe is adjusted within the sleeve. Use an electrical gap-measuring tool or monitor the transducer's DC voltage output (e.g., -10 VDC nominal gap for 3300 XL 8mm) while tightening the locking nut to prevent drifting from the target calibration.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem; border-radius: 4px;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 5px;\"\u003eCRITICAL WARNING\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eEnsure the machine is completely shut down and de-energized before mounting, adjusting, or servicing proximity probe housing assemblies.
