Omron H7CX-AU-N Multi-Function Digital Counter: Technical Guide, Applications and Installation
Maintenance teams know the difference between components that merely survive and ones that genuinely perform over the long haul. The Omron H7CX-AU-N Multi-Function Digital Counter falls firmly in the second category, making it a frequent first choice for mould shot counting environments.
For projects where sensing and switching decisions need to be made together, Omron’s Omron Sensor products are a natural companion to this unit. Both families are built to the same quality standards and documented to the same CE and UL requirements, which simplifies the declaration of conformity process.
Omron H7CX-AU-N — Product Profile
The Omron H7CX-AU-N is a Multi-Function Digital Counter, built to handle mould shot counting reliably over a long service life. Key engineering features include 8-digit lcd display, preset/batch/totalize modes, programmable, and the unit mounts via panel.
On the bench, 8-digit lcd display, preset/batch/totalize modes, programmable stands out immediately. The specifications align with the control voltage standards used across manufacturing, building automation, and process control industries, reducing the need for additional conversion stages.

Where This Product Fits
The Omron H7CX-AU-N Multi-Function Digital Counter is commonly specified for the following applications:
- Mould shot counting
- Batch production tracking
- Frequency measurement
Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron H7CX-AU-N is designed with exactly those conditions in mind.
Practical Installation Tips
The Omron H7CX-AU-N Multi-Function Digital Counter follows standard DIN rail mounting practice. Before inserting the unit into its socket or fixing it to the rail, always verify the circuit is fully de-energised. Check that cable cross-sections are appropriate for the load, and after commissioning, mark the panel clearly with the device type and rated voltage for future maintenance reference.
For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.
Performance You Can Rely On
From a total cost of ownership perspective, the Omron H7CX-AU-N Multi-Function Digital Counter makes financial sense even when its purchase price is higher than alternatives. Reduced unplanned downtime, fewer replacement cycles, and lower maintenance labour costs add up to a clear advantage over the operational lifetime of a machine.
Frequently Asked Questions
What is the difference between the Omron H7CX-AU-N and a mechanical contactor?
The Omron H7CX-AU-N Multi-Function Digital Counter is designed for panel-level signal and load switching at the current ratings specified. A contactor is built for direct motor starting at higher currents. For applications within the rated capacity of the Omron H7CX-AU-N, it offers faster switching, longer life, and a smaller footprint than a contactor.
How does temperature affect the Omron H7CX-AU-N?
Like all electromechanical devices, performance can be affected at the extremes of the operating temperature range. The Omron H7CX-AU-N is rated for use across a defined ambient temperature range — consult the datasheet for precise limits and any derating requirements at elevated temperatures.
Can I mount multiple Omron H7CX-AU-N units side by side on a DIN rail?
Yes. The Omron H7CX-AU-N Multi-Function Digital Counter is designed for standard DIN rail assembly with adjacent units. Ensure adequate total load current is within the rail and busbar capacity, and that enclosure ventilation is sufficient for the combined heat dissipation.
Does the Omron H7CX-AU-N include a test facility?
Depending on the model variant, some Omron relay sockets include a manual test button or push-to-test function. Check the specific socket model specified for the Omron H7CX-AU-N to confirm whether this feature is available.
How long is the warranty on the Omron H7CX-AU-N?
Omron provides a standard 12-month manufacturer warranty on products purchased through authorised distributors. Extended warranty options may be available — contact your local Omron distributor for details.
