NSL 32Sr3 Optocoupler, Photocell / LDR Output

We got these from Doctor Tweek!
 
The NSL-32SR3 from Advanced Photonix is a axial leaded optocoupler which consists of an LED input optically coupled to a photocell. The photocell resistance is high when the LED current is "off" and low when the LED current is "on".
Compact and moisture resistant package
Low LED current
Low "on" resistance
Fast rise and decay time
Passive resistance output
Best distortion characteristics
Peak isolation voltage of 2000V
Power dissipation of 50mW
Operating temperature range from -40°C to 75°C
