TT Electronics - Optek Technology OPS666 Infrared Sensor Pair

The OPS666 is a high-performance LED and photosensor pair designed for non-contact object detection and automation applications. It features a gallium arsenide infrared emitting diode paired with an NPN silicon phototransistor, mounted in a T-1 package for compactness or lateral side-looking plastic package for flexible installation. Suitable for use in reflective sensors, machine automation, assembly lines, and safety systems, it offers high current transfer ratio and low-cost construction. Its optical and electrical characteristics ensure reliable operation within a temperature range of -40°C to +100°C, with careful attention needed for ambient light sensitivity.
