Genuine EMERSON PR6423/11R-131 CON021 - Industrial Automation Part

EMERSON PR6423/11R-131 CON021 Eddy Current Proximity Sensor

Description

EMERSON PR6423/11R-131 CON021 Eddy Current Proximity Sensor – PR6423 Series

When a critical rotating machine loses its shaft position feedback, the consequences are immediate and severe: undetected rotor imbalance, catastrophic bearing failure, unplanned downtime measured in days, and repair costs that dwarf the price of a single sensor. In power generation, petrochemical refining, and heavy industrial environments, the PR6423/11R-131 CON021 is not a spare part — it is the frontline guardian of machine integrity, providing continuous, real-time eddy current proximity measurement that keeps turbines, compressors, and pumps running safely within design tolerances.

Within the EMERSON (Epro) PR6423 series — one of the most widely deployed eddy current sensor families in global industrial automation — the PR6423/11R-131 CON021 occupies a precision-grade position. The /11R-131 suffix designates a specific cable length and connector configuration, while CON021 identifies the companion extension cable assembly that completes the signal chain between the probe tip and the signal conditioner. Together, they form a calibrated system traceable to EMERSON’s API 670-compliant machinery protection standards, trusted by OEMs and end-users across six continents.
