2. Setup and Installation
Proper installation is crucial for the optimal performance of the TH-315 sensor. Follow these guidelines for a secure and effective setup:
- Mounting: Securely mount the sensor head in the desired detection area. Ensure it is stable and free from excessive vibration. The sensor should be positioned to allow the target metal object to pass through its detection zone without obstruction.
- Wiring: Connect the sensor's cable to the appropriate control unit or power supply. Refer to the wiring diagram provided with your control system for correct terminal connections. Ensure all connections are secure and insulated to prevent short circuits.
- Power Supply: Verify that the power supply voltage matches the sensor's requirements as specified in the technical specifications. Incorrect voltage can damage the unit.
- Environmental Considerations: Install the sensor in an environment that is within its specified operating temperature and humidity ranges. Avoid areas with strong electromagnetic interference if possible.

3. Operating Instructions
The TH-315 sensor operates on the principle of inductive proximity detection, specifically designed for fine metal objects. When a metal object enters the sensor's detection field, it causes a change in the sensor's oscillating circuit, triggering an output signal.
- Power On: Once installed and wired, apply power to the sensor system.
- Detection Area: Ensure the metal objects pass consistently through the sensor's detection aperture. The size and material of the metal object will influence the detection range and sensitivity.
- Output Signal: The sensor provides an electrical output signal upon detection. This signal can be connected to a PLC, counter, or other control device to initiate further actions (e.g., counting, stopping a process).
- Sensitivity Adjustment (if applicable): Some control units connected to the sensor may allow for sensitivity adjustments. Refer to your control unit's manual for details on fine-tuning detection.

4. Maintenance
The TH-315 sensor is designed for low maintenance. However, periodic checks can help ensure its longevity and consistent performance:
- Cleaning: Keep the sensor head free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners or solvents that could damage the sensor's 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: Periodically check that the sensor remains securely mounted and that all fasteners are tight.
5. Troubleshooting
If you encounter issues with your TH-315 sensor, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not detecting objects |
