Opto-isolator

• An optoisolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light.
• Opto-isolators prevent high voltages from affecting the system receiving the signal.
• Commercially available optoisolator withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 25 kV/μs.
• A common type of optoisolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually optoisolator transfer digital (on-off) signals, but some techniques allow them to be used with analogue signals.

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
