Instructions for Use:

1. Handling and Storage:

   • Store in a dry, cool place away from direct sunlight.
   • Handle with care to avoid static damage.

2. Mounting:

   • Ensure correct orientation during PCB assembly.
   • Avoid excessive heat during soldering; use temperatures not exceeding 260掳C for no more than 10 seconds.

3. 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.

4. 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.

5. 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.
