Optocouplers provide a means of optically isolated signal coupling. Whereas SSO's MOSFET and SCR Output SSRs provide integrated switching solutions, our broad line of optocouplers allows for flexibility where completely electronically isolated devices can be coupled discretely to a wide range of load handling components such as power MOSFETs and TRIACs.
Applications
Optocouplers are the ideal choice for:
- Office equipment — registers, copiers, fax machines and laser printers
- Home appliances — microwave ovens, washers and dryers, refrigerators and air conditioners
- Automatic vending machines
- Measuring instruments
- Signal transmission between circuits of different potentials and impedances
- Medical instruments, physical and chemical equipment
- Industrial robots and telephone sets
- Hybrid substrates that require high density mounting
- Computer terminals and programmable controllers
- Audio and video equipment
- Communications and telephony
- Switching power supplies
