Overview
The Epro CON021 + PR6423/013-030 configuration combines an eddy-current signal converter with an 8 mm proximity probe for non-contact displacement measurement. The converter processes the probe signal and provides a voltage output proportional to the measured gap. Furthermore, the separate converter and probe specifications help maintenance and procurement teams identify the individual components and check their operating conditions.
Product Configuration
The system consists of two separately specified components:
- CON021: Eddy-current signal converter with a self-locking LEMO sensor socket, screw terminals and voltage output.
- PR6423/013-030: 8 mm eddy-current proximity probe with an M8 x 1.0 mm metric thread and a 3 m standard cable.
The probe measures the gap between its sensing tip and the target surface. Meanwhile, the converter processes the sensor signal and produces a voltage output proportional to the gap. This arrangement provides a signal for displacement monitoring and associated measurement equipment.

Signal Measurement and Configuration
The PR6423/013-030 probe uses eddy-current sensing to measure the distance to a conductive target without physical contact. Its 2.0 mm linear range defines the specified measurement interval, while the initial sensitivity factor describes the relationship between gap displacement and output voltage.
Furthermore, the CON021 converter processes the probe signal and provides a voltage output for the connected monitoring equipment. The converter’s frequency response and rise time describe its signal response characteristics, while its gain error specifies the stated measurement accuracy over the 0 to 1000 Hz range.
Frequently Asked Questions
Q: What components are included in the CON021 + PR6423/013-030 configuration?
A: The specified configuration identifies the CON021 eddy-current signal converter and PR6423/013-030 proximity probe as two separate components. Their technical specifications are presented independently above.
Q: What is the measurement range of the PR6423/013-030 probe?
A: The probe has a linear measurement range of 2.0 mm (0.079 inches). Its initial sensitivity factor is 8.0 V/mm, and its output voltage is proportional to the measured gap.
Q: What power supply does the converter require?
A: The CON021 uses a nominal -24 VDC supply, with a specified operating supply range of -23 to -32 VDC. The probe specification also identifies a -24 VDC +/-10% supply via its converter.
