OP270

Infrared Light Emitting Diode in SMD Plastic Package OP270 Series • • • • • 890nm Wavelength Narrow Beam Angle High Power 1.9mm Water Clear Plastic Package Four Lead Configurations Description: The OP270 series are GaAlAs infrared LEDs mounted in a clear plastic SMT packages. The devices incorporate an integral molded lens which enables a narrow beam angle and provides an even emission pattern. This series is available with four lead configurations and is compatible with most automated mounting equipment. The OP270 Series LEDs are mechanically and spectrally matched to the OP570 series phototransistors. Applications • • • Non-Contact Position Sensing Datum detection Machine automation • • • Optical encoders IrDA Reflective and Transmissive Sensors Relative Radiant Intensity vs. Angular Displacement 100% OP272 OP271 OP273 Relative Radiant Intensity 80% 60% 40% OP270 20% 0% -90 -60 -30 0 30 60 90 Angular Displacement (Degrees) Pb RoHS A subsidiary of TT electronics plc Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
