Description

The 330881-16-00-180-03-02 PROXPAC XL Proximity Transducer assembly integrates a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor into a single, self-contained housing. This configuration eliminates the need for extension cables between the probe and the Proximitor sensor, as well as the requirement for separate Proximitor housings. The assembly is intended for machinery protection applications where space is limited or wiring complexity needs to be reduced. This specific unit features Option 16 (3300 XL 8 mm probe without approvals), Option 00 (no standoff adapter), 180 mm probe penetration, Option 03 (one M20 fitting), and Option 02 (3/4-14 NPT mounting thread). The housing is constructed from Polyphenylene Sulfide (PPS), a molded thermoplastic incorporating glass and conductive fibers to strengthen the unit and dissipate electrostatic charges. The assembly is rated for Type 4X and IP66 environments to provide mechanical protection in industrial settings.

Features

• Integrated design combines probe and Proximitor sensor in one unit
• Constructed from Polyphenylene Sulfide (PPS) for chemical resistance and electrostatic dissipation
• Supports direct wiring from machine monitors to the transducer housing
• Rated for IP66 and Type 4X environmental protection
• 3/4-14 NPT mounting thread configuration
• Includes M20 conduit fitting kit

Applications

• Critical rotating machinery vibration monitoring
• Axial position and shaft vibration measurement
• Retrofit projects where cable run reduction is required
• Applications requiring compact transducer installation in severe industrial environments

Installation Guidelines

• Ensure the housing is mounted securely to the machine case using the 3/4-14 NPT thread.
• The PPS housing is designed for direct field wiring; use appropriate M20 conduit connections to maintain the IP66/Type 4X rating.
• Avoid installing the probe in areas where side-view or rear-view effects from the machine case could interfere with measurement accuracy.
• Verify the gap between the probe tip and the target material is set according to standard 3300 XL proximity system practices.
