The SME and SMD series, from Honeywell, are discrete ceramic Infrared (IR) emitters. They are in compact surface mount (SMT) packages with a glass lens which helps to minimise crosstalk. These high intensity IREDs can be matched with both SMD2420 photodiodes and SMD2440 phototransistors. Suitable applications for the SMD series include; optical encoders for motion control, computer peripherals, vending applications, smoke detectors and medical equipment.
Glass-lensed optics for efficient optical coupling May be mounted upright or inverted Size: 3.81 x 2.54 x 2.1mm Matched to photodiode SMD2420 or phototransistor SMD2440
