NSL-32SR2 Datasheet, PDF (1/1 Pages) Silonex Inc. – Optocoupler

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”.
