The EPRO PR6423/000-000 is a non-contact eddy current displacement sensor designed for universal integration with PR6423 series driver systems. This base configuration offers maximum flexibility for custom cabling and mechanical mounting. It delivers the same precision measurement capability as the full assembly variants.

Bare Sensor Design for Custom Installations
The PR6423/000-000 arrives without an integral coaxial cable. Consequently, you retain complete freedom to select the appropriate cable type and length. This proves invaluable during retrofit projects with existing conduit systems. You simply solder your preferred RG178/U or equivalent coaxial cable directly to the sensor terminals.
Mechanical Footprint and Mounting Specifications
EPRO manufactures this sensor body from non-magnetic stainless steel. The M12 × 1 threaded barrel measures 45 mm in length. Two included hex nuts secure the PR6423/000-000 at your desired insertion depth. A 14 mm wrench provides the correct interface for installation and removal.
Temperature Resilience Without Active Components
This passive sensor contains zero internal semiconductors or energy storage devices. Therefore, it survives prolonged exposure at +180 °C probe tip temperature. You can mount it directly on turbine bearing housings without cooling adapters. The stainless steel construction also resists hydrogen sulfide and ammonia exposure.
System Compatibility and Signal Conditioning
You must pair the PR6423/000-000 with an EPRO CON011 or equivalent driver converter. The driver supplies excitation and demodulates the impedance signal. Together, they produce a voltage output linearly proportional to target displacement. This combination supports both proximity and vibration measurement simultaneously.
Simplified Logistics and Reduced Inventory
The PR6423/000-000 represents the common core across multiple PR6423 series variants. Stocking this base model minimizes inventory complexity. You simply add the appropriate cable assembly during installation. This approach reduces lead times and accommodates last-minute design changes.
