The Kingbright L-934EC is a 3 mm (T-1) Infrared (IR) LED, with peak wavelength of 940 nm. It is a high intensity, through-hole component, that is f3 mm (T-1) in size, with a narrow viewing angle of 15 degrees and a wide operating temperature range of -40 °C to +100 °C. The L-934EC is designed for use in opto-interruptors, positional encoders, and automated mechanical systems. It is made of a high quality plastic, and features a robust lead frame and superior electro-optical characteristics. The reliability of the L-934EC is enhanced by its extremely efficient thermal management.
