EPRO PR6423/000-101 Eddy Current Proximity Sensor

EPRO PR6423/000-101 is an 8mm eddy current proximity probe based on eddy current effect. It is a non-contact transducer designed for rotating machinery condition monitoring, converting the gap variation between probe tip and metal shaft into linear electrical output signals.

This sensor must work together with matching proximitor such as CON021 or CON041. It supports continuous measurement of shaft vibration and axial displacement, and is widely used as spare part for MMS6000 machinery protection system maintenance projects.
