Description：

The Bently Nevada 330880-16-00-021-03-02 PROXPAC XL Proximity Transducer is a compact, self-contained proximity transducer assembly that integrates a 3300 XL 8 mm proximity probe, 3300 XL Proximitor® sensor, and protective housing into a single unit. By eliminating the need for a separate extension cable and external Proximitor housing, the PROXPAC XL simplifies installation, reduces wiring requirements, and improves reliability in rotating machinery monitoring systems.

The housing is molded from Polyphenylene Sulfide (PPS) reinforced with glass and conductive fibers, providing excellent mechanical strength, corrosion resistance, and electrostatic discharge protection. Rated Type 4X and IP66, the assembly is well suited for harsh industrial environments where moisture, dust, and corrosive conditions are present. The field wiring connects directly between the monitoring system and the PROXPAC XL assembly, reducing installation time and maintenance requirements.
