2. Configuração e instalação
A instalação correta é crucial para o desempenho e a segurança ideais. Siga estas etapas cuidadosamente.
2.1 Desembalagem e Inspeção
- Carefully remove the sensor from its packaging.
- Inspect the sensor for any visible damage that may have occurred during shipping.
- Verifique se todos os componentes listados na nota de entrega estão presentes.
2.2 Montagem do Sensor
The S18AW3FF50 sensor is designed for easy mounting. Ensure the mounting surface is stable and free from excessive vibration.
- Select a mounting location that provides clear line-of-sight for the sensor's detection range (50 mm).
- Secure the sensor using appropriate mounting hardware (not included). The sensor features a threaded barrel for secure attachment.
- Ensure the sensor is oriented correctly for the intended detection application.

2.3 conexões elétricas
AVISO: Disconnect all power before making electrical connections to prevent electric shock or damage to the equipment.
The S18AW3FF50 operates on 20-250VAC input and provides an SPST Solid-State Light Operate output. The sensor comes with a 2M (6.5FT) cable.
| Cor do fio | Função |
|---|---|
| Marrom | AC Line (L1) |
| Azul | AC Neutral (L2) |
| Preto | Output (SPST Light Operate) |
Connect the sensor wires to the control circuit according to the provided wiring diagram and local electrical codes. Ensure all connections are secure.

3. Operação
Once installed and wired, the S18AW3FF50 sensor is ready for operation.
3.1 Ligando
Apply power to the sensor (20-250VAC). The sensor will typically have an indicator LED (if present) to show power status and output state.
3.2 Detection Principle
The S18AW3FF50 is a photoelectric sensor operating in a fixed field mode. It emits a light beam and detects objects based on the reflection or interruption of this beam. The "Light Operate" output means the output will be active when light is received by the sensor (i.e., when an object is detected or not detected, depending on the specific fixed field configuration).
3.3 Range and Performance
The sensor has a specified detection range of 50 mm. Ensure that objects to be detected fall within this range for reliable operation. Environmental factors such as dust, moisture, and ambient light can affect performance.
4. Manutenção
The S18AW3FF50 sensor is designed for low maintenance. Regular checks can ensure long-term reliable operation.
4.1 Limpeza
- Periodically clean the sensor lens and housing to remove dust, dirt, or debris that may accumulate and interfere with detection.
- Use a soft, lint-free cloth and a mild cleaning solution if necessary. Avoid abrasive cleaners or solvents.
4.2 Inspeção de Cabos e Conexões
- Regularly inspect the sensor cable for any signs of wear, cuts, or damage.
- Check electrical connections to ensure they remain secure and free from corrosion.
5. Solução De Problemas
This section provides solutions to common issues encountered with the S18AW3FF50 sensor.
| Problema | Possível causa | Solução |
|---|---|---|
| O sensor não liga. | No power supply; Incorrect wiring; Damaged sensor. | Verify power supply (20-250VAC); Check wiring against Table 1; Replace sensor if damaged. |
| Sensor not detecting objects | Object out of range (50 mm); Dirty lens; Misalignment; Ambient light interference. | Ensure object is within 50 mm range; Clean sensor lens; Realign sensor; Shield sensor from strong ambient light. |
| Intermittent detection | Vibration; Loose connections; Fluctuating power. | Secure sensor mounting; Check all electrical connections; Ensure stable power supply. |
