Klíčové vlastnosti:
- Typ: Photoelectric Retro-Reflective Sensor
- Typ hlavy: Úhlová hlava
- Rozsah detekce: Up to 4 meters (with suitable reflector)
- výstup: PNP (Push-Pull) with Light-On (LO) and Dark-On (DO) functionality
- Spojení: Konektor M12
- Stupeň ochrany: IP68/IP69K (High protection against dust and water ingress, including high-pressure/steam jet cleaning)
4. Nastavení a instalace
Proper installation is critical for optimal performance and longevity of the sensor.
4.1 Montáž
- Mount the sensor securely using appropriate brackets and fasteners.
- Ensure the sensing window is clear of obstructions.
- Position the sensor and reflector (not included) such that the light beam is not interrupted by ambient light sources or reflective surfaces other than the target reflector.
- The angled head allows for flexible mounting in confined spaces or for specific beam alignment requirements.
4.2 Zapojení
The sensor uses an M12 connector. Refer to the pinout diagram below for correct wiring.
| Kolík | Color (Standard) | Popis |
|---|---|---|
| 1 | Hnědý | +V (Operating Voltage) |
| 3 | Modrý | 0V (Uzemnění) |
| 4 | Černý | Output (PNP LO/DO) |
| 2 | Bílý | Not Connected / Function Input (Check specific model documentation if applicable) |
Connect the sensor to a stable DC power supply within the specified voltage range. Ensure correct polarity.
5. Návod k obsluze
The OKII403C0103 sensor operates by detecting the presence or absence of an object interrupting the light beam between the sensor and a retro-reflector.
5.1 Funkčnost
- Retro-Reflective Principle: The sensor emits a light beam that is reflected back by a special reflector. An object passing between the sensor and the reflector interrupts this beam, triggering the output.
- PNP Output: The output switches to a positive voltage (+V) when activated.
- Light-On (LO): The output is active when light is received (no object detected).
- Dark-On (DO): The output is active when no light is received (object detected).
5.2 Adjustment (if applicable)
Some models may feature a sensitivity adjustment potentiometer. If present, rotate the potentiometer to fine-tune the detection sensitivity for your specific application and reflector distance. Observe the status indicator LED (if present) to confirm proper alignment and detection.
6. Údržba
The Wenglor OKII403C0103 sensor is designed for minimal maintenance. Regular checks can ensure continued reliable operation.
- Čištění: Periodically clean the sensing window and reflector with a soft, damp hadříkem. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
- Inspekce: Regularly inspect the sensor, cable, and connector for any signs of damage, wear, or loose connections.
- Ochrana životního prostředí: Ensure the sensor remains within its specified operating temperature and humidity ranges. The IP68/IP69K rating provides excellent protection against water and dust, but avoid prolonged submersion or direct high-pressure spray if not necessary.
