TT Electronics - Optek Technology OP233 Infrared LED

The OP233 is a Gallium Aluminium Arsenide infrared emitting diode housed in a hermetic metal package. It provides a higher radiated output than standard gallium arsenide at the same forward current. Featuring a lens with an 18° beam angle, it emits at 890 nm wavelength, matching silicon phototransistor spectral response. Ideal for non-contact sensors, automation, and safety applications, it offers both focused and non-focused light patterns, an extended temperature range, and compatibility with related OPTEK devices for reliable performance in industrial settings.
