EPRO PR6424/012-010+CON011 Eddy Current Sensor – Obsolete EPRO Series Spare Part

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters such as sensitivity, gap range, and frequency response are system-configuration dependent. DriveKNMS does not publish unverified specifications. Contact us for datasheet access.

Solving the Discontinued Hardware Crisis

The EPRO PR6424 series was designed for precision non-contact measurement of shaft displacement and vibration in rotating machinery. These sensors were factory-calibrated to work within specific EPRO driver/monitor combinations — the PR6400 series monitors, and in many installations, integrated into Bently Nevada-compatible racks after the EPRO acquisition. The CON011 connector variant was specified for installations requiring a defined cable termination standard, making field substitution with generic sensors technically impractical without recalibration and potential re-certification of the monitoring loop.

Extending Automation Asset Life by 5–10 Years: A Practical Strategy for Plant Management

Facilities running EPRO-based vibration monitoring systems face a defined end-of-support horizon. The following approach has been used by maintenance teams to defer system replacement and protect capital budgets:

This approach has allowed facilities to operate EPRO-based systems reliably for 8–12 years beyond the manufacturer's end-of-sale date, deferring multi-million dollar DCS and machinery protection upgrades until a planned capital cycle.

Condition & Reliability Assurance

Sourcing discontinued sensors from the secondary market carries real risk. DriveKNMS applies a 5-step verification process to every PR6424/012-010+CON011 unit before it is offered for sale:

• Step 1 – Visual and mechanical inspection: Pin corrosion, connector body integrity, and cable jacket condition are assessed. Units with oxidized or mechanically damaged connectors are rejected.
• Step 2 – Electrolytic capacitor assessment: Where applicable in associated driver electronics, capacitor aging is evaluated. Sensors showing evidence of moisture ingress or thermal stress are quarantined.
• Step 3 – Firmware and configuration verification: For units with embedded configuration, version consistency with the target system is confirmed prior to dispatch.
• Step 4 – Functional output test: Each sensor is tested for correct output response within a controlled gap range using a calibrated test rig.
• Step 5 – Packaging and ESD protection: Units are packed in anti-static packaging with desiccant. Long-term storage units receive nitrogen-purged sealed packaging on request.

Key Features for System Maintenance

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Should I buy multiple units as long-term spares?
For any machine where a PR6424 sensor failure would cause a protective trip or production loss, holding a minimum of two spare units is the standard recommendation. Given the discontinued status of this part, availability on the open market will continue to decrease. Procurement now, while RFQ-reviewed sourcing status exists, is the lower-risk position.

Can this sensor be used with Bently Nevada monitors?
The EPRO PR6424 series was designed for EPRO driver/monitor systems. Compatibility with Bently Nevada hardware depends on the specific monitor model and configuration. Contact our technical team before ordering for cross-compatibility applications.
