OP775B [TT Electronics]

The series consists of NPN silicon phototransistors molded in an epoxy package with a wide receiving angle for relatively even reception over a large area. The side-looking package design allows easy PCBoard mounting of slotted optical switches or optical interrupt detectors. Devices are available with clear, opaque, or blue-tinted packages and have four sensitivity ranges. The OP750, OP755, OP770 and OP775 have additional circuitry to enhance operation for stray light levels. The OP552 features an integral lens in an opaque plastic package for visible light immunity. The OP555, OP565, OP755 and OP775 have an internal lens in a blue-tinted package with a 28° acceptance half-angle. These sensors are 100% production tested using infrared light for correlation with OPTEK's GaAs and GaAIAs emitters and are spectrally matched to OPTEK's infrared emitting diodes.
