PR6423-10R-010-CON021

PR6423-10R-010-CON021 combines a PR6423/10R-010 sensor with a CON021 converter for non-contact shaft measurement. The sensor uses an 8 mm tip, a 3/8-24 UNF case thread and reverse mounting. Its configuration includes an unarmored cable, an adapter plug, a 5.0 m cable-length option and a LEMO cable end. The sensor and converter must form the correct adjusted measurement chain; the cable is part of that electrical arrangement.

The standard PR6423 chain provides a 2 mm linear measurement range. Its incremental scale factor is 8 V/mm ±5% over 0 to 45 °C, with 42CrMo4 / AISI 4140 steel as the reference target material. Shaft material and installed gap affect the measurement relationship, so final gap adjustment uses the output of the complete converter-and-sensor chain. The signal can support radial or axial shaft displacement, position and eccentricity measurement when the monitoring channel is configured for the intended task.

CON021 provides a 0 to 20 kHz frequency response at -3 dB and a rise time below 15 µs. It uses a negative DC supply: -23 to -32 V for a -4 to -20 V output range, or -21 to -32 V for a -2 to -18 V output range. The sensor input uses a self-locking LEMO connection and the supply/output uses screw terminals. The converter is IP20 and rated -30 to +100 °C, whereas the sensor is IP66; therefore the converter enclosure and probe environment require separate assessment.
