Omron Z500-MC10E-001 Laser Profile Measurement System Controller

The Omron Z500-MC10E-001 is the controller unit for the Z500 profile measurement system, an industrial device that combines a laser line-beam projection method with a 2‑dimensional CCD to capture and measure the cross-sectional profile of an object without needing to move either the sensor or the target. Engineered for non-contact measurement, the Z500 system calculates critical profile parameters such as height, width, step difference, edge position, and angle. This method eliminates mechanical motion errors, providing stable, high-accuracy measurement for production quality inspection and process control.

Technical Specifications

Key Features

• Non‑Contact Profile Measurement Using Line-Beam Method: Unlike conventional point laser sensors that scan across an object by moving the sensor head, the Z500 projects a wide laser line onto the target and captures the entire reflected line on a 2D CCD in a single snapshot. This method eliminates motion artifacts, reduces system complexity, and provides stable measurement even for moving webs or discrete parts on a conveyor.

• Up to 2048 Points per Profile: The system captures high-resolution profiles with up to 2048 measurement points across the field of view, enabling detection of very small surface irregularities, edge dents, or connector pin alignment that would be missed with lower-resolution sensors.

• Multi-Item Measurement Capability: The Z500-MC10E-001 can be configured to output up to eight different measurement items simultaneously per profile, including height, width, step difference (two-point edge), area of a defined region, gap distance, and angle between two lines.

• Flexible Integration: A standard RS-232C port provides access to profile data and measurement results, while built-in digital I/O (4 inputs, 4 outputs) trigger measurements, receive external sync signals, and output alarm or OK/NG decisions for sorting.

• Onboard Data Processing and Storage: The controller includes signal averaging, selectable measurement ranges, and calibration routines. It stores profiles and can output analog voltage (0–10 V) or current (4–20 mA) proportional to the main measurement value, allowing connection to older panel meters, chart recorders, or PLC analog input cards.

Functional Overview

The Z500-MC10E-001 controller pairs with a Z500 series sensor head (sold separately, e.g., Z500-SW6). The sensor head contains a 650 nm wavelength laser diode and a 2D CCD array. The controller powers the laser, schedules the exposure timing, reads the CCD raw video data, performs real-time image processing (peak detection, interpolation), converts to real-world coordinates, computes measurement values, and transmits results.

Compatibility and System Configuration

The Z500-MC10E-001 is compatible with the Z500-SW6 series sensor heads, with various measurement ranges depending on the standoff distance and field of view. A complete Z500 system consists of a controller, a sensor head, and an interconnecting cable. The controller can be configured as a stand-alone measurement station with its own discrete I/O, or as part of a larger system with a PLC using RS‑232C commands.

Installation and Configuration

Mount the Z500-MC10E-001 controller on a DIN rail inside a panel. Connect the sensor head cable to the dedicated connector on the front of the controller. Provide AC power via the supplied terminal block. Using the front-panel buttons and the 11-segment display, the operator would set the measurement mode. For full configuration, connect a PC to the RS-232 port and run the Z500 Support Software. The software allows the user to set the measurement region, define up to eight measurement items, set tolerances and judge outputs.

Maintenance and Reliability

The controller is maintenance‑free except for cleaning the fan filter (if equipped) and verifying the calibration. The sensor head's protective window should be cleaned regularly, as dust or oil haze will attenuate the reflected laser signal and reduce measurement accuracy. The controller includes diagnostic flags for laser output degradation and CCD pixel saturation. Under normal conditions, the laser diode's lifetime is rated for more than 5 years of continuous operation. In case of a laser fault, the system will output an error signal via the alarm relay.

Conclusion

The Omron Z500-MC10E-001 controller provides a powerful, non-contact solution for profile measurement. By combining a line-beam laser and 2D CCD technology, the Z500 system enables stable, high-resolution inspection of complex geometries at production-line speeds, without requiring motion of the target.
