The IF-E92A and IF-E92B are blue LEDs in Industrial Fiber Optics鈥?family of low-
cost, medium-frequency, short-distance fiber optic LEDs and detectors. Each LED
and detector consists of a
polycarbonate (PC)
housing, an internal active element
such as an LED or photodetector subcomponent, and a cinch nut to hold the fiber
in place. The PC housing retains the active element and the cinch nut while
optimizing coupling between the active element and the jacketed 1000 碌m
plastic fiber.
The IF-E92A fiber optic LED contains a Silicon Carbide LED die, while the IF-
E92B contains a Gallium Nitride LED, the two LEDs producing a blue light
output center spectral wavelength of 430 and 470 nm, respectively. The blue
LED is a special purpose, low-cost device for producing blue light output without
the size, complexity and cost of a laser. The blue light is easily coupled with
the standard 1000 碌m jacketed plastic fiber for many sensing applications.
Working with this family of fiber optics is simple: no special tools or training
required. Only a sharp knife or razor blade is needed to terminate the plastic
fiber although Industrial Fiber Optics makes an easy-to-use cutter. When the
fiber is inserted in the LED or detector housing, tighten the cinch nut.
Thereafter, the fiber can be removed simply by loosening the nut.
