Why are they used?

Optocoupler provide Isolation: Optically transmited a Signal while electricially isolating the transmitting & receiving circuits. It protects Sensitive electronics (or us) from high Voltage spikes.

Applications / How do you spot opportunities?

Applications that use an infrared emitter, photo detector, or optical sensor:

• Smoke and Flame Detectors
• Long Range Presence and Proximity
• Short Range Presence and Proximity
• Ambient Light Sensors
• Touch Control
• Safety Barriers / Light Curtains
• Motor Control
• 3DTV Optical Solutions
• Remote Control
• Data Transmission
• Motor Control

How to ask for opportunities?

Did your Sesitive electronics / Human need to be Isolated from the Electric Spikes?
