Opto Couplers / Isolators

Also known as optical-isolators or photocouplers, these are electronic components that transfer electrical signals between two isolated circuits using light. Especially useful in low voltage or highly noise sensitive circuits to isolate circuitry and exclude unwanted noises. All Electronics carries a variety of opto-isolators/ couplers.
