3. Setup and Installation
Proper installation is crucial for the accurate and reliable operation of the IL-300 sensor. Follow these guidelines for setup.
3.1 Unpacking and Inspection
- Carefully remove the sensor and all accessories from the packaging.
- Inspect all components for any signs of damage during transit. If any damage is found, contact your supplier immediately.
- Verify that all components listed in the packing list are present.

3.2 Mounting the Sensor
The IL-300 sensor should be mounted securely to a stable surface using the provided mounting bracket and screws. Ensure the sensor is positioned to allow for the target to be within the specified measurement range (160 to 450 mm) and ideally at the reference distance (300 mm) for optimal performance.
- Attach the mounting bracket to the sensor using the appropriate screws.
- Secure the sensor assembly to the desired location, ensuring it is stable and free from vibration.
- Consider the ambient light conditions; while the sensor has resistance up to 5,000 lux (incandescent lamp), direct strong light sources should be avoided if possible.

3.3 Electrical Connections
Connect the sensor's cable to the appropriate power supply and control unit according to your system's wiring diagram. Ensure all connections are secure to prevent intermittent operation or damage.
- Verify the power supply voltage matches the sensor's requirements.
- Ensure proper grounding to prevent electrical noise interference.
- Avoid routing sensor cables near high-voltage lines or noise-generating equipment.
4. Operation
Once installed and connected, the IL-300 sensor is ready for operation. The sensor provides an analog output corresponding to the measured distance.
4.1 Powering On
Apply power to the sensor. Observe the operation status indicators on the sensor unit.
Figure 4.1: Close-up view of the IL-300 sensor's indicator lights (CENTER, A. RANGE, LASER).
4.2 Understanding Indicators
- Laser Emission Warning Indicator (Green LED): Illuminates when the laser is emitting.
- Analog Range Indicator (Orange LED): Indicates if the measured distance is within the analog output range.
- Reference Distance Indicator (Red/Green LED): Changes color to indicate if the target is at or near the reference distance. Consult the full product manual for specific color meanings.
4.3 Measurement Principles
The IL-300 uses a red semiconductor laser to measure the distance to a target. The sensor outputs an analog signal proportional to this distance. Ensure the target surface is suitable for laser measurement (e.g., not highly reflective or transparent without proper setup).
- The optimal measurement is achieved when the target is at the reference distance of 300 mm.
- The sensor can measure within a range of 160 mm to 450 mm.
- The sampling rate can be adjusted (0.33/1/2/5 ms) depending on the application's speed requirements.
5. Maintenance
The KEYENCE IL-300 sensor is designed for robust industrial use, but regular maintenance ensures its long-term reliability and accuracy.
- Cleaning: Periodically clean the lens cover (glass) with a soft, lint-free cloth. If necessary, use a mild, non-abrasive cleaning solution. Avoid harsh chemicals that could damage the lens or housing.
- Cable Inspection: Regularly inspect the sensor cable for any signs of wear, cuts, or damage. Damaged cables can lead to intermittent operation or complete failure.
- Mounting Security: Check that the sensor remains securely mounted and that all mounting screws are tight. Vibration can loosen connections over time.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature (-10 to +50 °C) and humidity (35 to 85 % RH, non-condensing) ranges. While the sensor has an IP67 enclosure rating, protecting it from excessive dust and moisture will extend its lifespan.
6. Troubleshooting
If you encounter issues with your IL-300 sensor, refer to the following common troubleshooting steps before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not powering on / No indicators lit | No power supply; Incorrect wiring; Damaged cable. | Check power connections and voltage. Verify wiring according to the system diagram. Inspect cable for damage. |
| Inaccurate or unstable measurements | Target outside measurement range; Dirty lens; Excessive vibration; Unsuitable target surface; Ambient light interference. | Ensure target is within 160-450 mm. Clean the lens cover. Secure mounting to reduce vibration. Consider target material/color. Reduce strong ambient light. |
| Laser emission warning indicator (Green LED) not lit | Sensor malfunction; Power issue. | Verify power supply. If power is present and other indicators function, the sensor may require service. |
| Analog range indicator (Orange LED) not lit or flickering | Target outside analog output range; Sensor not properly calibrated for application. | Adjust target position to be within the optimal analog range. Consult the full product manual for calibration procedures if applicable. |
If the problem persists after attempting these solutions, please contact your supplier or KEYENCE technical support for further assistance.
