Overview
The CON021 is an eddy-current signal converter designed to process signals from Epro PR6422 through PR6426 eddy-current sensors. It converts sensor signals into standard voltage outputs for monitoring and measurement equipment. The unit features a self-locking LEMO sensor connector, screw terminals for field wiring, and a frequency response of up to 20 kHz. One unit is currently in stock.
Signal Conversion and Sensor Connection
The CON021 accepts input from the PR6422, PR6423, PR6424, PR6425, and PR6426 eddy-current sensor families. Its self-locking LEMO socket provides the sensor connection, while screw terminals accommodate field wiring up to 1.5 mm².
Furthermore, the converter provides a standard output of -4 to -20 V or -2 to -18 V. Its 0 to 20 kHz frequency response and rise time below 15 microseconds support the processing of dynamic measurement signals.

Installation and Configuration Considerations
When selecting the CON021 and its associated sensor, check the sensor model, connector type, supply requirements, and output configuration. In addition, confirm that the converter output range matches the receiving monitoring equipment.
For example, the PR6423/013-000 falls within the stated PR6422 through PR6426 sensor input range. However, the sensor and converter specifications should be checked independently before wiring or replacement.
Frequently Asked Questions
Q: Which sensors can connect to the CON021?
A: The CON021 accepts Epro PR6422 through PR6426 eddy-current sensors. The PR6423/013-000 is within this specified model range.
Q: What output signals does the CON021 provide?
A: The specified standard output options are -4 to -20 V and -2 to -18 V. Check the required output configuration before connecting the converter to monitoring equipment.
Q: Are the CON021 and PR6423/013-000 the same product?
A: No. The CON021 is a signal converter, whereas the PR6423/013-000 is an eddy-current sensor. They perform different functions and have separate electrical and mechanical specifications.
