Description:Each OP215 and OP216 device is an 890 nm gallium aluminum arsenide infrared emitting diode (GaAIAs), mounted in a hermetically sealed “pig tale" package with an enhanced temperature range and a narrow irradiance pattern 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 mounting. The OP216A device provide an additional mounting tab connected to the Cathode/Case. these LEDs are mechanically and spectrally matched to the OP300 series, OP516, OP600 series and OP640 series devices.Features: Hermetically sealed package Mechanically and spectrally matched to other OPTEK devices Designed for direct mount to PCBoard Enhanced temperature rangeApplications: Non-contact reflective object sensor Assembly line automation Machine automation Machine safety End of travel sensor
