ZX Series New Line-up of Wide-line-beam Sensors (30-mm Width)!

Multi-point Measurement and Calculation Functions Further Expand the Application Coverage.

Features

Multi-Point Measurement with Calculation Functions

Use of the ZX-CAL2 Calculating Unit makes it easy to configure inspection systems requiring outer diameter (A-B) or width (A+B) calculations.

The ZX-SAM14 Multi-point Smart Sensor Package lets you easily perform multi-point calculations on a personal computer.

Remote (External) Reference Light Intensity Setting (Use ZX-LDA[]1-(N)-01)

The reference light intensity can be set to cancel measurement errors due to the effects of paper dust and other matter when there is no sensing object present. This enables high-speed meandering control.

"Front" APC Function

Front APC (Auto Power Control) reduces the effect of light reflecting from wafers. Ideal for high-precision, high-speed orientation flat positioning.

Front APC Function

Technology

Front APC nulls the effects of light reflections from workpieces with mirror surfaces

The output power of the semiconductor laser in conventional laser sensors has to be monitored and controlled. When reflections from the workpiece enter the built-in monitoring photodiode that is used for this purpose, the output power changes and adversely affects the measurement. The ZX-LT030 uses front APC technology to solve this problem.

Integrated APC Method (Conventional Laser Sensor): Light reflected from the workpiece returns directly to the monitoring photodiode inside the laser diode, which reduces the output power and causes measurement errors.

Front APC Method (ZX-LT030): Light reflected from the workpiece does not return to the external monitoring photodiode, so there is no change in output power.

Application Examples

Checking the width of rubber sheets; Checking the outer diameter of metal pipes; Detecting meandering with coated cardboard sheets; Detecting rail distortion.
