Omron ZX-LDA41 Amplifier Unit with ZX-LD300L Laser Displacement Sensor

The Omron ZX-LDA41 amplifier unit combined with the ZX-LD300L laser displacement sensor forms a complete Smart Sensor measurement system from Omron ZX series. This intelligent sensor system is designed for high-precision non-contact measurement of position, displacement, and thickness in industrial automation applications. The ZX series utilizes advanced laser technology and CMOS sensing elements to deliver accurate measurement results across a wide range of target surfaces and environmental conditions. The system comprises a sensor head that emits laser light and detects reflected light, and an amplifier unit that processes the signal and provides measurement outputs.

ZX-LD300L Sensor Head Specifications

The ZX-LD300L is a diffuse reflective laser displacement sensor head with line beam configuration. The sensing distance ranges from 300 mm ±200 mm, providing a total measurement range of 100 mm to 500 mm from the sensor. The resolution is 300 μm, suitable for applications requiring moderate precision over longer measurement distances. The line beam pattern enables stable measurement on targets with surface variations or texture. The sensor head is part of the comprehensive ZX series product line, which includes both reflective and through-beam sensor heads offering various sensing distances and resolutions to suit different application requirements.

ZX-LDA41 Amplifier Unit Features

The ZX-LDA41 amplifier unit provides the processing power and interface connectivity for the ZX series smart sensor system. The amplifier unit offers a range of features including linear output, judgement outputs, and various input and function options. It can be configured to provide either current or voltage output depending on the application requirements. The amplifier includes self-diagnosis functions such as laser deterioration detection and zero reset memory for long-term measurement stability. The ZX-LDA41 is available in PNP output configuration, compatible with standard industrial control systems. The unit operates on 12-24 V DC power supply and supports connection to the sensor head via dedicated cabling.

System Capabilities and Functions

The ZX series smart sensor system provides multiple measurement modes including distance measurement, thickness measurement, and step measurement. The amplifier unit includes judgment outputs for high, low, and pass/fail indication, enabling direct integration into sorting and quality control applications. The system supports various timing inputs including laser OFF input, zero reset input, and timing input for synchronized measurement with external equipment. When combined with the ZX-CAL2 calculating unit, the system can perform calculations such as (A-B) and (A+B) for differential measurement, mutual interference detection, and simultaneous measurements using two amplifier units.

Applications

The Omron ZX-LDA41 and ZX-LD300L system is deployed in industrial measurement and inspection applications requiring non-contact displacement sensing. Typical applications include position monitoring on assembly lines where part presence and position must be verified, thickness measurement of sheet materials such as metal, plastic, and paper, vibration monitoring on rotating machinery, and sorting applications where objects must be classified by height or size. The system is also used in semiconductor manufacturing for wafer positioning, in packaging machinery for fill level detection, and in automotive assembly for gap and flushness measurement where the 300 mm sensing distance allows mounting away from the target area.
