The 7.6 in case is useful when the bracket or housing requires a longer body to position the probe tip at the target while retaining locknut access. The 0.5 m lead then needs a suitable nearby connection to the rest of the 3300 XL 8 mm system.

Support the long case through the intended threaded interface, preserve clearance around the locknut and route the short lead without pull force. This reduces the chance that bracket stress changes probe position or damages the connector.

Inspect the protected ClickLoc joint and cable continuity before moving the probe gap. A response to connector movement points toward the connection path, while a stable connection shifts attention back to mounting and target conditions.

The extension cable must produce a documented total system length with the 0.5 m probe lead and the matching 8 mm Proximitor Sensor. Selecting only by connector appearance can create an electrically mismatched loop.

Record the installed depth, locknut position, target gap, connector condition and cable route before removal. Those references make reinstallation faster and reduce the risk of losing the previous mechanical baseline.

Option 00 does not add an agency-approval selection, so the model should not be accepted for that requirement on the code alone. Compare the actual label and project specification before release.
