Description:
Each LED/Photosensor pair in the series consists of a gallium arsenide infrared emiƫng diode and a NPN silicon phototransistor, mounted in a T-1 package (OPS665, OPS666, OPS667) or in a matched lateral side-looking plasƟc package (OPS690, OPS691, OPS692, OPS693 and OPS695, OPS696, OPS697, OPS698).
Matched pairs are desirable where the applicaƟon is unique and the quanƟty required does not jusƟfy assembly tooling costs. If separaƟon between the LED and sensor is greater than two Ɵmes the specified IC(ON) distance, proper alignment becomes criƟcal. Although sold as pairs, emiƩers and sensors are packaged separately for handling ease.
Please note that the sensor is sensiƟve to ambient light.

FEATUREs:
• High current transfer raƟo
• Low-cost plasƟc package
• T-1 package style with three current range selecƟons (OPS665, OPS666,
   OPS667)
• Lateral side-looking clear plasƟc package (OPS690, OPS691, OPS692, OPS693
   and OPS695, OPS696, OPS697, OPS698)
  
Applications:
• Non-contact reflecƟve
   object sensor
• Assembly line automaƟon
• Machine automaƟon
• Machine safety
• End of travel sensor
