Switching can be achieved while maintaining a high degree of isolation between driving and load circuits. These optocouplers can be used to replace reed and mercury relays with advantages of long life, high speed switching and elimination of magnetic fields. 2 5 6 .335 (8.50) .343 (8.70) .039 (1.00) Min. 4 typ. .018 (0.45) .022 (0.55) .300 (7.62) typ. .048 (1.22) .052 (1.32) .130 (3.30) .150 (3.81) 18 .031 (0.80) min. 3-9 .031 (0.80) .035 (0.90) .114 (2.90) .130 (3.0) .010 (.25) typ. .300-.347 (7.62-8.81) .100 (2.54) typ.
