OP270

Infrared Light Emitting Diode in SMD Plastic Package OP270 Series • • • • • 880nm Wavelength Narrow Beam Angle High Power Four Lead Configurations 1.9mm Water Clear Plastic Package 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 Part Number Description Material Lead Style OP270 LED, SMD, 1.9mm Molded GaAlAs Axial OP271 LED, SMD, 1.9mm Molded GaAlAs Gull-Wing OP272 LED, SMD, 1.9mm Molded GaAlAs Yoke Bend OP273 LED, SMD, 1.9mm Molded GaAlAs Reverse Gull-Wing Relative Radiant Intensity vs. Angular Displacement OP272 Relative Radiant Intensity 100% OP271 80% OP273 60% 40% OP270 20% 0% -90 -60 -30 0 30 60 Pb 90 Angular Displacement (Degrees) LEAD FREE Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.

Ee(APT) is a measurement of the apertured radiant incidence upon a sensing area 0.081” (2.06mm) in diameter, perpendicular to and centered on the mechanical axis of the lens, and 0.590” (14.99mm) from the measurement surface. Ee(APT) is not necessarily uniform within the measured area.
