Proximity Transducer

330880-28-00-035-01-02:

330880-28-00-035-01-02 is a PROXPAC XL Proximity Transducer Assembly (English version). It is a self-contained proximity probe system that integrates a 3300 XL 8 mm Probe (1.0 m cable), 3300 XL Proximitor Sensor, and housing into a single PPS assembly. It features a 3.5-inch probe sleeve and includes one 3/4-14 NPT conduit fitting. This design eliminates the need for an external extension cable and a separate Proximitor housing.

Important Cautions - 330880-28-00-035-01-02

Self-Contained System: The Proximitor sensor is integrated inside the housing cover. The 1.0-meter probe cable connects directly to the Proximitor, eliminating the probe-to-extension-cable connection point. Field wiring runs directly from the PROXPAC XL to the monitoring system.
Total Penetration Length: The combined length (BB + CCC) is 7.8 inches (198 mm). This is below the 12-inch (305 mm) limit, so no additional sleeve support (P/N 37948-01) is required.
Probe Penetration Calculation Note: The effective probe penetration into the machine is the sum of the standoff adapter length plus the sleeve length. In this model: 1.5" (standoff) + 6.3" (sleeve) = 7.8" total.
No Extension Cable: The PROXPAC XL is a 1.0-meter system only. It is not compatible with 5-meter or 9-meter system configurations. The entire system length from probe tip to Proximitor is fixed at 1.0 meter.
Fittings Option: Option DD = 00 provides no conduit fittings — only two plugs and two washers are supplied to seal unused housing ports.
