Compatibility and Selection Guide
This housing assembly is compatible with Bently Nevada 3300 XL 8 mm proximity probes. The 3/4-14 NPT mounting thread and 1.5 in standoff adapter match standard conduit interfaces. When ordering, verify the probe penetration (6.5 in) and cable length (1.0 m) suit your machine casing. The -04 fitting option provides one 3/4-14 NPT plug only; additional conduit fittings are available separately. For hazardous areas, confirm the specific approval required, as only CA versions are CSA explosion-proof with E:00, E:01, E:02, or E:04 options.
Installation and Maintenance
Install the Bently Nevada 21000-34-10-15-065-04-02 by threading the housing into a 3/4-14 NPT port and securing the probe sleeve. The dome cover screws into the housing body for access. O-rings and a thread seal ensure environmental protection. Regular inspection of the probe and cable is recommended; the 304 stainless steel sleeve resists corrosion. The assembly weighs 1.1 kg without fittings, simplifying handling. For technical support and quick dispatch, contact PLC Source PRO.
