Product Introduction
The Epro PR6423/011-110 + CON021 is a high-precision eddy current proximity sensor system developed for use in industrial environments demanding reliable, continuous monitoring of shaft displacement, vibration, or axial thrust in rotating machinery. Known for its superior performance, rugged construction, and reliable operation in harsh conditions, this sensor system forms a critical part of many condition monitoring and protection systems.
Engineered with a measuring tip diameter of 8mm, the PR6423/011-110 probe pairs with the CON021 converter to deliver a linear, contactless displacement signal based on eddy current principles. The sensor’s ability to operate in extreme temperature zones and resist electromagnetic interference makes it a trusted solution in petrochemical, power generation, and heavy mechanical industries.
