Combines the 3300 XL proximity measurement chain with a protective field housing.
Technical Summary
330881-28-00-265-00-02 is the metric PROXPAC XL configuration for a 3300 XL 8 mm probe with multiple approvals.
Its ordering string specifies no standoff adapter, 265 mm probe penetration, no fittings with two plugs and two washers, and a 3/4-14 NPT mounting thread.
The integrated assembly is intended to preserve the probe, Proximitor electronics and protective housing as a defined transducer configuration.

Features
Provides the standard 200 mV/mil scale factor for the stated 8 mm system.
Supports a 265 mm penetration while retaining the exact thread and fitting configuration.
Offers Type 4X/IP66 environmental protection when installed and sealed correctly.
Compatibility
- Match the complete 330881 suffix; penetration, fittings and mounting thread are not interchangeable details.
- Use the approved power, barrier and field-wiring arrangement for the site classification.
- Verify target material, target size, probe gap and cable routing against the monitoring design.
- Do not mix a separate probe or Proximitor calibration chain into the integrated assembly without manufacturer guidance.
Replacement
- Record label, gap voltage, penetration reference, barrier identity and monitor-channel configuration before removal.
- Isolate the machine protection channel under the approved bypass and permit procedure.
- Install the exact mechanical configuration, seal unused entries and protect the field cable from strain.
- Verify gap, scale, polarity, vibration response and alarm path before restoring protection.
FAQ
What proves a replacement is the correct 330881-28-00-265-00-02 configuration?
The full nameplate must match the 28, 00, 265, 00 and 02 ordering positions; photographs of the mounting and conduit arrangement are also useful.
Can the field cable be extended beyond the installed distance?
The datasheet allows field wiring up to 305 m, but cable type, capacitance, barriers and site wiring practice must remain within the approved design.
Why should the recommended gap be checked after mechanical work?
Housing or probe movement changes the operating point; a stable 1.27 mm nominal gap keeps the system within its stated linear range.
Does the Type 4X/IP66 rating apply with an open conduit entry?
No. The housing must be assembled, plugged and sealed using the approved fittings to maintain environmental protection.
What final test should be documented?
Record supply voltage, gap voltage, channel response, alarm and trip behavior, and the restored bypass state.
