Miniature IR LEDs promise longer life

OP180 and OP280 Series IR LEDs are ideal for noncontact position sensing, datum detection, machine automation, and optical encoding applications.

Optek Technology has developed a comprehensive range of surface mount infra-red LEDs in plastic leadless PLCC-2 packages with a silicon encapsulant that increases the operational life of the component.

"Customers are continuously requesting components with increased functionality and that are miniature in size for operation in applications with limited real estate", says Alan Bennett, vice president of sales and marketing for Optek Technology.

"This family of IR LED devices offers a competitive solution due to the stability of the components and variance of light emitted, while meeting space constraints in both single device and array applications".

The OP180 Series and OP280 Series of surface mount infra-red LEDs include the following components.

The OP180 is a high-power GaAs device with 940nm peak wavelength, 0.50mW/cm2 apertured power, 20mA IF and 100-degree half-power angle.

The OP280K is a high-power GaAlAs LED with 875nm peak wavelength, 0.85mW/cm2 apertured power, 20mA IF and 90-degree half-power angle.

The OP280KT is a high power GaAlAs device with reverse-polarity terminals, 850nm peak wavelength, 0.85mW/cm2 apertured power, 20mA IF and 90-degree half-power angle.

The OP280PS is a point-source GaAlAs LED with 850nm peak wavelength and smaller spot size, 0.15mW/cm2 apertured power, 20mA IF and 50-degree half-power angle.

And the OP280V is a high-performance 850nm invisible VCSEL (class 1M) with 2.50mW/cm2 apertured power, 7mA IF and 18-degree half-power angle.

The OP180 and OP280 Series IR LEDs are ideal for noncontact position sensing, datum detection, machine automation, and optical encoding applications.

Typical pricing for the OP180 and OP280 Series IR LEDs starts at US $0.22 each in quantities of 1000 pieces.

Production quantity lead times, if stock is not available, are from 6 to 8 weeks.
