NSL-32SR2 Optocoupler Features · Compact, moisture resistant package · Lowest “on” resistance · Very low LED current · Passive resistance output · Low distortion Description This optocoupler consists of an LED input optically coupled to a photocell. The photocell resistance is high when the LED current is “off” and low resistance when the LED current is “on”.
