Description:
Each OP123 and OP124 device is a 935 nanometer (nm) high intensity gallium arsenide infrared emi􀆫ng diode (GaAs),
mounted in a miniature herme􀆟cally sealed “pill” package with an enhanced temperature range and a high power output.
These devices are designed for direct moun􀆟ng to PCBoards.
Each OP223 and OP224 device is an 890 nm gallium aluminum arsenide infrared emi􀆫ng diode (GaAIAs), mounted in a
herme􀆟cally sealed “pill” package with an enhanced temperature range and a narrow irradiance pa􀆩ern that provides high
on-axis intensity for excellent coupling efficiency. These devices offer significantly higher power output than GaAs at
equivalent drive currents and have a wavelength that is matched to silicon’s peak response. Their small package size
permits high device density moun􀆟ng.
All these LEDs are mechanically and spectrally matched to the OP300 series, OP600 series and OP640 series devices.

Applications:
• Non-contact reflective object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End of travel sensor
• Door sensor
