It is intended for locations where the probe body size prevents use of an 8 mm probe. Confirm the M8 × 1 thread and 40 mm case reach, but do not assume the 5 mm family also reduces required side-view clearance.

First restore the documented static gap at the same machine condition. A stable gap with an abnormal dynamic signal points the investigation toward the cable path, Proximitor Sensor or channel configuration rather than probe position alone.

It should be used as part of the matched 3300 5 mm system. Before connecting it, identify the installed extension cable and Proximitor Sensor; an 8 mm component should not be accepted merely because the connector mates.

Support the cable close to the probe, keep it away from hot or moving surfaces and avoid tight bends. If the route cannot protect the lead from abrasion or vibration, revise the routing before commissioning the new probe.

Review the official mounting clearances and inspect the bracket or housing around the tip. The smaller probe body does not eliminate side-view effects, so changing the probe without correcting surrounding metal may leave the same error.

Compare the complete model, M8 × 1 thread, 40 mm case, 1 m lead and code 02 connector treatment with the installed record. This prevents a visually similar 5 mm probe from being released to the wrong machine.
