Each device in this series is a high intensity gallium aluminum arsenide infrared emitting diode that is suited for use as a PCBoard mounted slotted switch or an easy mount PCBoard interrupter. Each dome lens OP240A and OP245 device is an 890 nm diode that is molded in an IR-transmissive clear epoxy side-looking package. OP240A is mechanically and spectrally matched to the OP550 and OP560 series of phototransistors. OP245 is mechanically and spectrally matched to the OP555 and OP565 series devices.
