TT Electronics - Optek Technology | OP298A

The OP298A is a gallium aluminum arsenide infrared Light Emitting Diode (LED). That is molded in an IR-transmissive package with a wavelength centered at 890 nm, which closely matches the spectral response of silicon phototransistor.

It has an included emission angle of 25°. The Cathode Lead length is 0.06” (1.52 mm) shorter than the Anode Lead. These devices, which come in a variety of power ranges offering a low cost replacement for TO-18 or TO-46 hermetic packages.

Features:

• Choice of narrow or wide irradiance pattern
• Choice of power ranges
• Choice of T-1¾, TO-18 or T-46 package
• Higher power output than GaAs at equivalent LEDs

Applications:

• Non-contact reflective object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End of travel sensor
• Door sensor
• Battery-operated applications
