Instructions for Use:
Handling and Storage:
- Store in a dry, cool place away from direct sunlight.
- Handle with care to avoid static damage.
Mounting:
- Ensure correct orientation during PCB assembly.
- Avoid excessive heat during soldering; use temperatures not exceeding 260°C for no more than 10 seconds.
Electrical Connections:
- Connect the input side (LED) to your control circuit ensuring the forward current does not exceed 5mA.
- Connect the output side (phototransistor) in series with a suitable load resistor to limit collector current within 50mA.
Safety Precautions:
- Do not exceed the maximum ratings specified to prevent damage.
- Maintain adequate isolation between primary and secondary circuits especially when dealing with high voltages.
Testing:
- Verify functionality by applying a known input signal and measuring the corresponding output response.
- Check for continuity and insulation resistance as part of routine maintenance.
