Infrared Components SME/SMD Series Ceramic Discrete Surface Mount Emitters and Detectors FEATURES • Small package size • Glass lensed optics for efficient optical coupling • Upright or inverted mounting capability • Low profile, small size for flexible layout of multiple channels and custom arrays • Compatible with automated solder processes: - IR reflow - vapor phase - solder wave - convection oven • Choice of photodiode or The SME2470, SMD2440 and SMD2420 Series surface mount phototransistor detectors infrared components are small ceramic packages (0.15 x 0.10 x • IRED features high power 0.083 in. / 3,81 x 2,54 x 2,1 mm) with glass lenses. The lens minimizes dissipation capability cross talk and often eliminates the need for apertures in non-critical • Tape and reel packaging applications. The low profile components may be mounted on the option - pick and place printed circuit board, lens up or inverted, allowing flexibility in layouts for machine compatible multiple channel and custom arrays. When mounted lens down over a hole in the PC board, the lens is hidden, lowering overall package APPLICATIONS height. • Optical encoders for motion The SME2470 is a high intensity aluminum gallium arsenide infrared control emitting diode (IRED) which can be used with either the SMD2440 • Computer peripherals phototransistor or the SMD2420 photodiode. It supplies optimum optical • Vending and point-of-sale characteristics and efficient optical coupling. The small size and high applications power dissipation properties of the IRED promote PC board • Smoke detectors miniaturization and high density placement. • Medical equipment The SMD2440 Series phototransistor’s gain characteristics make it useful for applications requiring high responsivity. The SMD2420 Series photodiode is especially useful in applications requiring linear response or high switching speed. These components are available in bulk, or on tape and reel for use with automatic placement equipment. Honeywell Sensing and Control
