Bently Nevada 330880-28-20-45-01-02 | Proximity Transducer

Overview:

The 330880-28-20-45-01-02 PROXPAC XL Proximity Transducer by Bently Nevada combines the functionality of a proximity probe and its associated sensor in a compact, self-contained system. Designed for use in harsh environments, this assembly eliminates the need for separate Proximitor housing or extension cables, making installation more efficient and reliable. The PROXPAC XL features a robust Polyphenylene Sulfide (PPS) housing, offering enhanced electrostatic charge dissipation and extra protection against severe conditions.

Features:

• Integrated 3300 XL Proximitor sensor.
• No need for extension cables or additional Proximitor housing.
• Polyphenylene Sulfide (PPS) housing with glass and conductive fibers.
• Rated for Type 4X and IP66, ideal for challenging environments.
• Simple field wiring with direct connection to monitors.
