NSL-32SR2

NSL-32SR2 Optocoupler Features • • • • • Compact, moisture resistant package Lowest “on” resistance Very low LED current Passive resistance output Low distortion 25.4 min. Photocell 2.54 5.7 min. Anode lead 0.25 x 0.51 + LED 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”.
