LED and Photosensor Pairs
OPS666, OPS667, OPS691, OPS692, OPS693,
OPS698
Features:
• High current transfer ratio
• Low-cost plastic package
• Lateral side-looking clear plastic package (OPS691, OPS692, OPS693 and
OPS698)
OPS666 - 667
OPS691 - 693
OPS698
Description:
Each LED/Photosensor pair in the series consists of a gallium arsenide infrared emitting diode and a NPN silicon
phototransistor, mounted in a T-1 package (OPS666, OPS667) or in a matched lateral side-looking plastic package (OPS691,
OPS692, OPS693 and OPS698).
Matched pairs are desirable where the application is unique and the quantity required does not justify assembly tooling
costs. If separation between the LED and sensor is greater than two times the specified IC(ON) distance, proper alignment
becomes critical. Although sold as pairs, emitters and sensors are packaged separately for handling ease.
Please note that the sensor is sensitive to ambient light.
Applications:
• Non-contact reflective object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End of travel sensor
• Door sensor
