Key Features
Non-Contact Eddy-Current Measurement
Provides precise, repeatable shaft displacement measurements without mechanical contact, eliminating probe wear while maintaining long-term accuracy.
Compact 2-Inch Probe Body
The 2.0-inch (50.8 mm) case length is well suited for installations with limited mounting space while maintaining compatibility with the complete 3300 5 mm system.
Miniature ClickLoc® Connector
The ClickLoc® connector provides a secure connection that resists loosening under vibration and simplifies installation and maintenance.
Rugged Construction
The probe features a stainless-steel body and PPS probe tip for excellent resistance to industrial environments, oils, and elevated temperatures.
Hazardous-Area Certifications
The 05 approval option includes Multiple Approvals (such as CSA, ATEX, and IECEx), allowing installation in certified hazardous locations when installed according to applicable requirements.
Factory-Calibrated System
The probe is intended for use only as part of the complete 3300 5 mm Proximity Transducer System, together with a compatible extension cable and Proximitor® Sensor, ensuring calibrated performance and component interchangeability.
Frequently Asked Questions
