TT Electronics - Optek Technology OP599A Optical Phototransistor

The OP599 series consists of NPN silicon phototransistors housed in a dark blue injection-molded plastic package, ideal for applications requiring narrow receiving angles up to 20°. These sensors exhibit excellent optical lens surfaces and precise chip placement, providing consistent performance in space-limited environments. They are designed for reliable optical coupling with GaAlAs emitters, with features supporting high sensitivity, fast response, and robust operation across a wide temperature range from -40°C to +100°C. Suitable for optical sensing, object detection, and automation systems demanding high precision and durability.
